Mechanical Installation

Installation of Rear Bottom Trims

The first step of the mechanical installation is the installation of the rear bottom trims (shipped in Accessory Kit).

Slide the rear bottom trims into the grooves and secure, using the 8 bolts (M6) provided for the Inverter Section and External Bypass SSW and the 4 bolts (M6) provided for the Control and Input/Output Sections. Screws are included in Accessory Kit.

Note

When installing rear bottom trims on the UPS, be sure to align the holes in the trim with the holes in the UPS.

Note

Mount the rear bottom trims (shipped in Accessory Kit), using the taller trim for the rear of the sections.

Note

Mount the rear bottom trims before positioning and bolting the sections for seismic protection.

For torque values, refer to “Torque specifications” under “Specifications” .

Note

Do not install front bottom trims until all system wiring has been completed.

See details on the installation of front bottom trims in the “Front Bottom Trims and Panels” section.


Positioning the UPS Sections

All illustrated procedures show the Inverter Section being positioned first. The positioning sequence of the UPS sections is optional. Other solutions may be more practical under the given conditions. Other solutions involve rearrangements of the frame-joining brackets (see “Turning the frame-joining brackets” ).

Turning the frame-joining brackets

Loosen the bolts and nuts from the frame-joining bracket and remove.

Turn the frame-joining bracket and attach using the bolts and nuts from step 1.

Note

Before positioning the UPS sections in their final installation area, remove any finishing and dead front panels remaining on the system (as described in Appendix C).

If the system requires bolting to the floor for seismic protection, see “Seismic Anchoring” section before proceeding.

Note

Ensure that the open angle of the frame-joining bracket of the section positioned first is facing upwards, and that the open angle of the frame-joining bracket faces downwards on the neighbouring section so they can interlock.


Mechanical Installation: Positioning the UPS Sections

Positioning Configuration 1

Using a forklift, position the Inverter Section in its final position. Use level shims (in Accessory Kit shipped with unit) if required (illustration ).

Using a pallet jack or forklift, position and lower the Control Section. Allow the frame-joining bracket on the left foot of the Control Section to slide into the frame-joining bracket of the right foot of the Inverter Section (illustration ). Use level shims if necessary (illustration ).

Note

If the configuration includes an IP21 Drip Cover, proceed to the “IP21 Drip Cover (Option)” section before positioning and securing the system sections.

If holes have not been pre-drilled, refer to the drawings in the Site Preparation Guide.

Note

Applicable only to systems with an IP21 Drip Cover. If installing the UPS configuration against a wall, leave a gap of 30 mm between the configuration and the wall.

Note

Hole size for seismic protection = 15 mm.

Note

Mount rear bottom trims (shipped in Accessory Kit) before positioning and bolting the system for seismic protection.


Mechanical Installation: Seismic Anchoring

Seismic anchoring procedure

When seismic anchoring holes have been drilled, position the Inverter Section.

Secure the Inverter Section using washer and bolt. Do not fully tighten anchors at this stage.

Feet must be level. Use level shims (shipped in Accessory Kit) to level feet if necessary.

Follow the same procedure to position the Control and Input/Output Sections, and the External Bypass SSW.

When all sections are in place, make sure that they are straight and level.

Specifications

Low-Impedance/High-Impedance Grounding

The Symmetra® MW is easily integrated into either a solid grounded Wye system, or a high-impedance grounded system.

In a solid grounded system, the neutral power source (utility, generator, or UPS) is solidly grounded. In the event of a down-stream ground fault, the fault current will have a path back to the source, and the over-current device feeding the faulted part of the installation will trip and isolate the fault.

In a high-impedance grounded system, the source is grounded with an impedance (grounding resistor). In the event of a down-stream fault, the fault current will be limited by the impedance of the grounding resistor. The value of a high-impedance system is its ability to maintain operation with a given system fault to ground, i.e. the over-current device will only trip at line-to-line faults or double ground faults. For a high-impedance system to provide enhanced power system reliability and availability, a ground-fault monitoring/alarm system is required.

Note

Appendix D - System and Protective Earthing

The purpose of this appendix is to describe the system- and protective earthing principles of the Symmetra® MW.



TN Systems

Characteristics

TN systems have one point connected directly to ground. All exposed conductive parts must be connected to that point by protective conductors.

Depending on the way the neutral and protective conductors are fed, there are three types of TN systems:

• TN-S system: a separate protective conductor is used in the system

• TN-C-S system: the neutral and protective conductors are combined to one single conductor in a part of the system

• TN-C system: the neutral and protective conductors are combined to one single conductor in the whole system

Reference to IEC 60364-4-41 413.1.3

All exposed conductive parts of the installation must be connected to the earthed point of the power system by protective conductors which must be earthed at or near to each relevant transformer or generator.

Exposed conductive parts that are accessible at the same time must be connected to the same earthing system, either individually, in groups or collectively.

Normally the earthed point of the power system is the neutral point. If a neutral point is not available or accessible, a phase conductor must be earthed. The phase conductor must not serve as a PEN conductor.

In fixed installations a single conductor may serve both as a protective conductor and a neutral conductor (PEN conductor).


If from any point in the installation the neutral and protective functions are provided by separate conductors, it is inadmissible to connect these conductors to each other from that point. At the point of separation, separate terminals or bars must be provided for the protective and neutral conductors. The PEN conductor must be connected to the terminal or bar intended for the protective conductor.

If there are other effective earth connections, the protective conductors must be connected to such points when it is possible. It may be necessary to earth at additional points to ensure that the potentials of protective conductors remain as close as possible to that of earth in case of a fault.


Appendices: TN Systems

Additional requirements for generating sets (IEC 60364-5-55 551.4.2)

To be used when the generating set provides a switched alternative to the public supply.

Protection by automatic disconnection of supply must not rely on the connection to the earthed points of the public supply system when the generator is operating as a switched alternative to a TN system. A suitable earth electrode must be provided.

Protective devices in TN systems

The following protective devices are recognized in TN systems:

• Overcurrent protective devices

• Residual current protective devices (not to be used in TN-C systems)

When a residual current protective device is used in a TN-C-S system, a PEN conductor must not be used on the load side. The connection of the protective conductor to the PEN conductor must be made on the source side of the residual current protective device (see below illustration):

Appendices: TN Systems

The characteristics of protective devices and the circuit impedances shall be such that, if a fault of negligible impedance occurs anywhere in the installation between a phase conductor and a protective conductor or exposed conductive part, automatic disconnection of the supply will occur within 5 seconds (valid for distribution circuits), the following condition fulfilling this requirement:

In the condition:

If a fault occurs close to the UPS (before the power distribution) while the UPS system is in Battery Operation and Bypass is unavailable, the available power is unable to activate the protective device. In that situation the Inverter will shut down in five seconds (IEC 60364-4-41 413.1.3.5 norm). If a residual current protective device is used, this device will disconnect the supply.

The four diagrams show the Symmetra MW installed in four different TN systems:

• Earthing arrangements and protective conductors - Symmetra® MW in “TN-S installation”

• Earthing arrangements and protective conductors - Symmetra® MW in “TN-S installation” (Legal in DK - special cases)

TT Systems

Characteristics

TT systems have one point connected directly to ground and all exposed conductive parts of the installation must be connected to an earth electrode. This earth electrode is independent of the power system earthed point.


All exposed conductive parts that are protected collectively by the same protective device must be connected to a common earth electrode together with the protective conductors. In installations where several protective devices are utilized in series, the requirement applies separately to all exposed conductive parts protected by each device.

The neutral point or, if a neutral point does not exist, a phase conductor of each generator station or transformer station must be earthed.

Protective devices in TT systems

The following protective devices are recognized in TT systems:


• Residual current protective devices

Overcurrent protective devices are only applicable for protection against indirect contact in TT systems where a low RA value exists (see specification below).

The condition must be fulfilled.

In the condition:

For discrimination purposes, S-type residual current protective devices may be used in series with general type residual current protective devices. To provide discrimination with S-type residual current protective devices, an operating time not exceeding 1 second is permitted in distribution circuits.

Appendices: TT Systems

When the protective device is an overcurrent protective device, it must be either:

• a device with inverse time characteristics and Ia must be the current causing automatic operation within 5 seconds, or

• a device with an instantaneous tripping characteristic and Ia must be the minimum current causing instantaneous tripping

• Earthing arrangements and protective conductors - Symmetra® MW in “TT installation”


IT Systems

Characteristics

In IT systems the installation is insulated from earth or connected to earth through a sufficiently high impedance. Exposed conductive parts are earthed individually, in groups, or collectively.


In IT systems the installation must be insulated from earth or connected to earth through a sufficiently high impedance. This connection must be made either at the neutral point of the system or at an artificial neutral point. The latter may be connected directly to earth if the resulting zero-sequence impedance is sufficiently high. In installations where no neutral point exists, a phase conductor can be connected to earth through an impedance. In case of a single fault to an exposed conductive part or to earth, the fault current will be low and disconnection will not be imperative.

Exposed conductive parts must be earthed individually, in groups or collectively and the condition must be fulfilled.

In the condition:

In systems where an IT system is used for continuity of supply, an insulation monitoring device must be provided to indicate the occurrence of a first fault from a live part to the exposed conductive parts or to the earth. It is recommended to eliminate a first fault as soon as possible.

Depending on whether all exposed conductive parts are interconnected by a protective conductor (collectively earthed) or are earthed in groups or individually, after a first fault, the disconnection conditions of the supply for a second fault must be as follows:

a. In installations where the exposed conductive parts are earthed in groups or individually, the protection conditions for TT systems apply (see 413.1.4.1)

b. In installations where the exposed conductive parts interconnected by a protective conductor collectively earthed, the conditions for TN systems apply

In installations where the neutral is not distributed, the following conditions must be fulfilled:

is the resistance of the earth electrode for exposed conductive parts

is the fault current of the first fault of negligible impedance between a phase conductor and an exposed conductive part. The Id value takes the leakage currents and the total earthing impedance of the electrical installation into account
