Chapter 3 Installation – Arc-Resistant
Load Cable Connections
1. Complete the Power Lockout procedure (See
2. Remove the appropriate cable conduit opening plate(s) from the cabinet
(see
). 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
).
4. Remove any front 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 any current transformer barriers removed and reassemble the
cabinet.
ATTENTION:
To avoid shock hazards, lock out incoming power
Power Lock-out Procedure on page 49
) 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
See
Recommended Line and Load Cable Sizes on page 10
. For
larger cables, an incoming line module must be used.
Stress cones should be internal non-skirted style only. The use of
external style (skirted style) is not recommended due to space
considerations.
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 will defeat the arc
resistant capabilities of the structure and may result in
electrical faults and cause damage to equipment or serious
injury to personnel.
