3. SHIPPING, HANDLING AND STORAGE

On receipt of motor after delivery, ensure that no damage has occurred during transit. If there is

any evidence of damage to the packaging then the motor must be inspected and checked by

qualified personnel before putting into service.

This equipment must be lifted at the appropriate lifting points attached to the frame. The lifting

gear must be suitable and have the carrying capacity of the full weight as indicated in the data

sheet and on the motor name plate.

Precautionary measures should be taken to protect the motor from vibration, water and extreme

temperature variations during transit. Damage can occur to the bearings from vibration and to the

windings from water and extreme temperature changes through condensation.

Transit clamps should be used to prevent the shaft from moving during transit. It is important to

remove these clamps (if fitted) before attempting to install the motor. These clamps should be

removed during storage to allow the shaft to be rotated by hand on a regular basis, at least once

every four weeks.

To prevent damage to the bearings it is recommended that the shaft is given a few turns by hand

every four weeks to load the bearing at different places randomly.

If motors are to be stored before installation, precautions must be taken to prevent deterioration.

Motors should be stored in a dry condition, standing clear from damp, free from condensation

and protected from extremes of temperature. If damp storage cannot be avoided then connect the

motor heaters. Adequate precautions must be taken for electrical safety as parts of the motor will

be live.

The motors should be protected from the ingress of dust, especially concrete/cement dust. When

protecting motors from dust, care should be taken that condensation is not caused.

Motors must be stored away from corrosive or chemically damaging fumes.

Damage can be caused to ball and roller bearings if these are subject to vibration.

It is recommended that the motors are thoroughly inspected at 6 monthly intervals. See Section 8

– General Inspection and Maintenance.

Inspect bearing grease before putting motor into operation and renew if it has been deteriorated.

Contact LTI for the replacement interval of grease under long storage periods.

Check insulation resistance before putting motor into operation. If this is less than 1 Megohm,

carry out drying operation.

REV 00 Page 7 of 18

4. INSTALLATION AND COMMISSIONING

Before putting this machine into service, it is important that checks be made to ensure that

the machine is suitable for use in the operating area classification. – See attached

certifications if applicable.

Refer to EN 60079-14 for installation instructions and any National and/or Site Safety Standards

(Within Europe), along with all applicable National, Industry and Company Standards and

Practices for Machinery Installations for all other regions.

If the motor is to be installed in a potentially explosive atmosphere, perform an ignition hazard

assessment in accordance with EN 13463-5 (Non electrical equipment intended for use in

potentially explosive atmospheres – Protect by constructional safety) to ensure the original

approval has not been compromised.

On receipt of motor after delivery, ensure that no damage has occurred during transit. If there is

any evidence of damage to the packaging then the motor must be inspected and checked by

qualified personnel before putting into service.

The motor must be lifted using the facilities provided.

Ensure that the motor rating plate data meets the required specification exactly. Operating the

motor outside the stated design limits could cause a potential hazard and will invalidate the

certification and manufacturers warranty.

The installation must provide for adequate guarding of rotating or heated parts. Where fitted,

these guards must be in position and secured.

Adjustments or measurements must not be made through ventilation or similar openings unless

the motor has been disconnected from the supply.

Any cover provided for live electrical parts or connections must be in place, to ensure that

ingress protection IP54 minimum is maintained.

Power cables to the motor must be of adequate current carrying capacity and rated for the

appropriate voltage. These cables must meet the requirements of the industry standards, local and

national electrical codes.

If operating in a hazardous area, the motor must always be installed using suitable cable

glands or adapters that have been certified by a Notified Body as meeting the requirements

of ATEX Directive 94/9/EC.

When the motor is supplied with loose (“Flying Leads”) cables permanently connected to it,

these cables must be protected and the free ends of the cable must be connected using an

approved method. Ensure that precautions are taken to prevent disconnection whilst energized.

Incoming cables must be suitably clamped, secured and insulated.

Page 8: 400 HP Motor Rotary Table Drive Motor

REV 00 Page 8 of 18

If used the RTD‟s/Kilxons used for overload protection must be connected to separate (i.e. Not

part of the VFD) circuit. The RTD/Klixon circuit must be set to no more than 170ºC. This will

provide overload and over temperature protection as specified on the certificate. See section 6.

The motor must be grounded (earthed) in accordance with EN 60079-14 and any National and/or

Site Safety Regulations or Industry Standards if none of the others are applicable.

Precautions must be taken to avoid vibration, high/low temperature extremes, corrosive and dirty

environments. If in doubt, contact LTI.

All circuits must be connected in accordance with the connection diagram supplied with the

motor along with this manual and all applicable drawings.

It is essential that the motor is supplied with sufficient ventilation from ambient air. It is

recommended that the controls for the ventilation system operate in conjunction with the main

motor drive system and ensures that ventilation is available at the same time as the motor starts.

If the motor is operated without cooling air, then heating will occur and the drive will trip on

over temperature. To prevent this, it is recommended that a zone approved air pressure switch,

which forms part of an intrinsically safe circuit, is fitted within the ventilation system, or the

cooling blower motor is interlocked to prevent the motor stating without the blower running.

Confirm that air flow is sufficient, that ventilation openings are free from obstruction and re-

circulation of the motor outlet air is not possible.

Before starting it is necessary to confirm that the shaft is free to rotate.

The motor must be run without excessive vibration. Ensure that the application adheres to this

equipment.

Drain points must be open and free from obstruction.

Ensure that a suitable coupling is used for the application of the motor.

Check alignment of the motor coupling to ensure there is no more than five thousandths of an

inch in misalignment.

Soft Foot, a condition where the four mounting feet are not in the same plane causing the frame

to distort, should be avoided to obtain proper alignment. A measurement of ±1.0 mils during

installation and ±1.5 is acceptable.

Page 9: 400 HP Motor Rotary Table Drive Motor

REV 00 Page 9 of 18

Ensure that any and all items used to secure the motor shaft during shipping have been removed

and that the motor shaft rotates freely prior to start-up.

Check the motor heaters. See Section 7.

5. OPERATION

The motor is rated S1 for continuous duty and is designed to work without constant supervision,

however, a periodic check of its performance is advocated.

The normal reading of ammeters under all conditions of the operation of the machine should be

known and if it deviates from the normal, the machine should be stopped (when operating

conditions permit) and the system inspected for faults.

When the machine is under normal operating conditions the frame will increase in temperature

over the ambient. There are thermal devices fitted to ensure that this rise in temperature does not

become a hazard.

6. THERMAL PROTECTION (REQUIRED FOR ATEX APPLICATION ONLY)

The motor will be fitted with over temperature protection for the stator windings. If specified at

the time or order, bearing temperature monitoring facilities can also be fitted. Refer to the motor

data sheet for number and type of thermal protection used.

It is the responsibility of the end user to connect the thermal protection that is fitted to the motor

to ensure safe operation.

Thermal protection for the windings must form part of an intrinsically safe circuit. The standards

require that one thermal protection device is fitted in each phase as a minimum. It is essential and

fundamental to the ATEX certification, that the thermal protection thermal protection is

connected to a separate trip circuit, which will remove power to the Variable Frequency Drive to

protect the motor from overheating and thus prevent a potential explosion hazard occurring.

One thermal protection device per phase must be connected to a separate and intrinsically safe

control circuit. This ensures that thermal protection is always maintained, even in the event of a

fault with the drive. It is required that the thermal sensing devices cause the drive circuit

breaker to open on rise of temperature. This circuit breaker must require a manual reset.

Failure to adhere to this requirement may cause the certification to become void.

The additional set of three RTD‟s may be routed back to the inverter drive for control and/or

temperature monitoring.

Thermal devices will be stated in the motor data sheet. Typically, these will be RTDs (PT100),

or Klixons.

Page 10: 400 HP Motor Rotary Table Drive Motor

REV 00 Page 10 of 18

7. HEATERS

Heaters are fitted integral to the motor winding during manufacture. To prevent condensation

causing deterioration to the insulation resistance of the winding, heaters should be switched on

when the motor is not in operation. Adequate safety measures must be taken to ensure that access

to live connections cannot be made whilst the heaters are energised.

The heater power circuit must be interlocked with the drive to ensure that power to the heater is

removed when the motor is running.

8. GENERAL INSPECTION & MAINTENANCE

!! WARNING !!

!! ELECTRICITY CAN KILL !!

All work on electrical installations should be closely controlled and a “Permit to Work” system

is highly recommended along with a “Lockout” procedure according to Local and/or National

standards.

Do not touch cables unless it is known to be safe!

Beware of rotating shafts: Secure any loose clothing etc!

Do not use cleaning solvents in confined spaces without adequate ventilation!

!! Important Note !!

The inspection and maintenance of this machine shall be performed by experienced

personnel, whose training has included instruction on various types of protection and

installation practices, the relevant rules and regulations and on general principles of area

classification.

This machine is intended for use in Potentially Explosive Atmospheres, Zone I, Group IIC

and as such, we recommend that for any overhaul or repair work, the machine be returned to

Oilfield Electric Marine to ensure that the „Increased Safety‟ protection concept to the

applicable standards is maintained.

Any repair arranged by the end user, unless expressly approved by manufacturer, releases the

manufacturer from his responsibility to conformity.

Page 11: 400 HP Motor Rotary Table Drive Motor

REV 00 Page 11 of 18

Inspection and Maintenance

Check the motor at regular intervals and develop an inspection/maintenance routine. The

following minimum requirements must be met.

Weekly: Visual Inspection.

An inspection which identifies, without the use of tools or accessing the equipment, those defects

such as loose bolts or covers, cable insulation and ground connection which are apparent to the

eye. Check that air flow is sufficient and that there are no obstructions to the intake and exhaust

vents of the motor and blower. Check the motor bearings for signs of overheating, discoloration,

excessive vibration and abnormal noise.

Monthly: Close Inspection.

With the machine safely switched of and locked out, inspect physically and tighten any loose

bolts, covers and guards.

6 Monthly: Detailed Inspection.

With the machine safely switched off and locked out, check for loose terminations, where

accessible and without removing insulated connections unless they are obviously in need of

attention.

Check the condition of shaft seals and replace if necessary.

Bearing condition can be checked by listening for excessive noise, inspection of used grease,

observing/monitoring bearing temperatures or measurement of vibration.

Add grease to the bearings. (2oz per bearing)

Replace the bearings every 25,000 hours of use.

Check the insulation resistance to ground (earth) and between phases with the motor leads

disconnected from the drive. Use motor heaters if insulation resistance to ground is below 1

megohm.

In no instance must the motor design be modified.

If the motor needs to be rewound, this may only be carried out by the manufacturer or nominated

representative. Failure to do so will invalidate the certification and warranty and could

compromise design features that affect the conformity to the specifications.

Page 12: 400 HP Motor Rotary Table Drive Motor

REV 00 Page 12 of 18

9. HUB REMOVAL

To remove the hub, always use a hydraulic pump assembly which is specially designed for this

purpose. Such as, an Enerpac Test Pump, (SEE CHART BELOW) capable of producing 40,000

psi.

Contact OEM for details of this pump or similar models.

This is simple, yet leaves the motor shaft in perfect condition and ready for reinstallation of the

hub after bearings have been changed. There is no need to use “Strong Back” type pullers and

heat Should Not Be Applied with this method.

To remove the hub:

i) Clean the end of the shaft inside the hub and remove the small plus in the

end of the shaft using the appropriate sized Allen wrench.

ii) Fit the knurled nut onto the threads of the shaft and make up all the way.

Then back off the nut until the hole in the shaft is visible and accessible.

iii) Fit the pump adapter into the shaft hole and tighten all the way. Insert the

pump tube extension and attach the pump. Ensure that the pump is placed

safely onto a raised block in line with the shaft to prevent bending the

tubing.

iv) Close the pump valve and apply pressure until it becomes difficult to

apply any more pressure. Then, pump the handle a couple of times and

the hub will break loose. The hub will not fall off the shaft as the knurled

nut will prevent this.

v) Open the pump valve and remove all fittings. Close the pump valve again

and stow all of the tools used for hub removal.

vi) Reinsert the Allen screw into the end of the shaft, loosely until the hub is

to be replaced onto the shaft.

vii) NOTE: When reinstalling the hub, be sure to remove the Allen screw

before fitting the heated hub onto the shaft. Then, after the hub and

shaft have cooled, replace the screw into the end of the shaft and

tighten so that it is a snug fit. Do not over tighten this screw!
