Load Cable Connections
1. Complete the Power Lockout procedure (refer to Power Lock-out
Procedure on page 41 of Chapter 5 ).
2. Remove the appropriate cable conduit opening plate(s) from the cabinet
(see Figure 32 and Figure 33 ). The plate may be punched or cut to mount
conduit.
3. Load cables for the power cell should be routed before control cables. Pull
the cables into the cabinet through the appropriate opening (see Figure 32
and Figure 33 ).
4. Remove current transformer barriers.
5. Connect the cables to the current transformers and tighten the
connections to 65 N•m (48 lb•ft).
6. Connect cable shields (if present) to the ground lug.
7. Reinstall the current transformer barrier and reassemble the cabinet.
ATTENTION: To avoid shock hazards, lock out incoming power (refer to Power
Lock-out Procedure on page 41 of Chapter 5 ) before working on the equipment.
Verify with a hot stick or appropriate voltage measuring device that all circuits
are voltage free. Failure to do so may result in severe burns, injury or death.
IMPORTANT The current transformers may be positioned for top or bottom cable exit.
Follow the appropriate procedure described for your starter configuration.
IMPORTANT Cable size should not exceed 1-500 MCM or 2-4/0 per phase. For larger cables,
an incoming line module must be used.
TIP Refer to Dimensional Drawings provided with order Documentation for
additional details related to cabinet Floor plan.
ATTENTION: Ensure all barriers are replaced before re-energizing the
equipment. Failure to do so may result in electrical faults and cause
damage to equipment or serious injury to personnel.
