Introduction
Eaton supply all busbar sections
tested in accordance with type test
requirements as detailed in IEC61439-
6 and are subject to a full Quality Check
before packaging.
In order to ensure that the Busbar remains
in this condition during transport,
unpacking and installation on site, it is
important to study this document.
If the guidelines outlined within this
document are not adhered to, this could
give rise to the damage of the product,
electrical failure of the Busbar, personal
injury, or even death.
Manual Lifting
In accordance with Manual Lifting
Regulations the guidelines below are
provided to reduce risk of injury to
personnel and damage to equipment
during transport and installation of
busbar section.
PPE (Personal Protection Equipment)
should be worn at all times in accordance
with Health and Safety Regulations and
specifi c site requirements. When lifting
Busbar sections, care must be taken to
lift each section along its centre and not
by the end sections or conductors.
Mechanical Lifting
Some sections of Busbar may require
mechanical lifting due to their weight.
Options for mechanical lifting includes
Genie® Lift™, forklift, scissor lift,
platform lift and block and tackle. A full
assessment of the risks should be carried
out by the installer before commencing
work.
The Busbar must be safely secured to
the lifting apparatus before lifting.
Always check that the load does not
exceed the safe working load of the
lifting apparatus. Ensure that equipment
is used as per manufacturer’s guidelines.
Storage
The Busbar will be delivered to the
customer neatly stacked on a wooden
pallet for ease of removal. The maximum
weight of the pallet will not exceed
2500kg.
The Busbar is protected from minor
water ingress by means of an overall
outer polythene wrap and individual
polythene stretch wrap around the
ends of each busbar. The stretch wrap
should be left in position until the bar is
mounted and Joint Pack fi tted.
If the Busbar is not to be installed
immediately upon delivery it should be
stored in a heated, clean, dry area not
exposed to wind, rain, frost, or physical
damage.
Busbar should never be stored outdoors.
This Installation Manual is designed to assist in the Safe Handling and Installation
of the Eaton Power Xpert XP2. These instructions are in addition to normal safe
working practices as required by the local health and safety regulations. These
instructions do not in any way advocate a departure from these requirements. THIS EQUIPMENT

Installation
Busbar
The Busbar Sections are secured to a framing system, such as Unistrut®, using the
Fixing Brackets as shown to the right. The bar can be secured both on its fl at and on
its edge.
Before lifting a Busbar Section, ensure that a detailed risk assessment is carried out
for the lifting procedure being performed in that specifi c area.
Eaton recommend that the fi xing brackets must be mounted no more than 500mm
from the centre of the joints. For vertical riser installation of sections greater than 2
metres it may be easier to lower the Busbar trunking from the fl oor above where it is
to be installed or from a fi xing on the ceiling of the same fl oor if at the end of the run.
Care is to be taken not to damage ends of the trunking when raising from horizontal
to vertical position.

Step 5.
Tighten the joint pack assembly using a 19mm spanner until the
shear nut breaks and the indicator disk drops off then tighten
to 65Nm ±5Nm using a calibrated torque wrench with a 19mm
socket. If installed correctly the joint will appear level and no
overlapping should appear. If overlapping of the Expansion
Ribs is apparent then the joint is not installed correctly.
The shear nut will break when torqued to 65Nm ±5Nm in a
clockwise direction. This will cause the indicator disc to fall off.
Step 6.
Megger the installed joint pack to ensure it is fi tted correctly.
Following a visual inspection to ensure that there are no
anomalies such as foreign material etc, install the front
joint pack cover.

Cable End Box
This is generally the fi rst component to be mounted on a rising busbar.
The entire route should initially be inspected for any obstructions before installation.
The box should be installed at the correct height in accordance with the approved
drawings.
A plumb line should be applied at this point from the start of the run to the end of
the run, as a guide for the vertical installation of the Busbar Run.
4 of M10x20 bolts c/w Bellville washers and a 17mm socket are required to install the
Cable End Box following the instructions shown.Unistrut rail

Maintenance of Busbar
Prior to carrying any maintenance work (other than thermal
imaging), ensure the Busbar is completely electrically
isolated by isolation, verifi cation and lock off of the supply
device in accordance with isolation procedures / method
statement.
Familiarisation with IEE Wiring Regulations or similar Local
Safety Standards should be understood in order to ensure
safe isolation of the Busbar Trunking.
Thermal Imaging should be conducted along the Busbar
route to identify any possible problems.
Once identifi ed a preventative maintenance program should
be instigated with the Busbar isolated as described above
before carrying out any work.
If joints are found to be loose they should be re-torqued
to the correct torque level as outlined in the Installation
Detail. If a joint is found to be loose but it shows no sign
of overheating simply re-torque the joint and conduct an
Insulation Resistance test prior to re-energising.
If slight discolouration occurs remove the joint and clean the
conductor with a fi ne grade (240) abrasive paper. Re-install
the joint and megger test.
If adverse overheating has occurred, please contact Eaton
for further details.
Megger test results at this point could be lower than those
taken during the fi rst installation test. As long as the reading
does not measure below 5M at 100VDC the system is
atisfactory for re-energisation.
Maintenance of Tap Off Module
As with the main Busbar system the joints require checking on the Tap Off connections. Thermal Imaging can identify localised heat spots. As previously described, upon identifying a local
problem preventative maintenance should be investigated with the busbar isolated.
If discolouration has occurred on the contact due to overheating, ensure the gap between contact’s are consistent and have not been damaged during transport, if they have, please contact Eaton.
If the joints show slight discoloration, clean them and re-tighten. If adverse overheating has occurred, please contact Eaton for further instruction. Visually check the installation of the Tap Off Module, check clamping mechanism, check door-interlocking device to ensure it still operates correctly. Check outgoing cable connections and gland tightness / integrity. Check the operation of the switching device positive ‘ON’, ‘OFF’ operation. Examine protective device for sign of short circuit operation. If a short circuit has occurred on the equipment connected to the tap off module check operation of device and the integrity of the device.
Energising
The Busbar should be energised immediately after following
steps 1 to 6 (shown above).
Only authorized, competent personnel should energise
electrical circuits in line with „switching procedures” and
„permit to work’ forms provided by the Site Electrical
Supervisor.
All connected load to the Busbar Trunking via tap offs for
example should be isolated prior to energizing the bar.
The Main Supply switch to the Busbar is to be energised
fi rst.
The Protection Settings should be at the circuit breakers
minimum protection level.
Only when the Busbar is being put into service are the
Protection Settings set to the specifi ed fi gures.
Following the successful closing off the supply breaker, close
the circuit breaker(s) supplying the connected loads (via Tap-
Offs) one by one.
Visually inspect the energised Busbar route to look for any
anomalies. Listen for noises from the system as this could
indicate untightened cover plates.
Prior to Energising
3 test must be completed prior to energising
Step 1. A continuity test to verify the run is complete.
Step 2. A ductor test to check the resistance of the joints
through the entire length.
Step 3. A megger test, 1000VDC between each conductor
and Earth. Readings will vary widely between site to site due
to length of run, humidity, temperature and site conditions.
If readings less than 5M are obtained, measures must be
taken to identify the location of the low resistance level and
take appropriate measures to increase the resistance level.
This test should only be carried out by competent personnel.
Step 4. Ensure all tap off boxes have been correctly installed
as instructed and are in the ‘ON’ position for insulation
resistance testing.
Step 5. Ensure all connections to the Busbar / tap offs have
been disconnected.
Step 6. Verify that all joints have been torqued according to
the recommended setting and have not been subsequently
loosened. Ensure all joint covers are fi rmly secured.
Step 7. When reconnecting the system prior to energisation,
ensure correct Phase Rotation is achieved by testing prior to
energising the supply.
Step 8. Ensure all tap offs are turned off again prior to
Energising.
Step 9.The testing procedure should be performed and
documented as per Eaton standard testing procedure
available on request.
