12. Replace the terminal guard assembly (reverse the operation in
step 2 of “Installing Cable” on page 2).
13. Inspect the BPS. With power off, operate the switch two or three
times to check that it is functioning properly and has not been
adversely affected by the switch maintenance.
Points of inspection:
•
BPS cover has been replaced and the eight screws have been
properly tightened.
•
Terminal guard assembly has been replaced and the three
terminal guard screws have been tightened.
•
Contact blades mate, close, and bolt correctly.
•
The arc chutes have not inadvertently been moved and do
not interfere with the operation of the contact blades.
14. Refer to the CENTERLINE 2100 Low Voltage Motor Control
Centers Instruction Manual, publication 2100-IN012, supplied
with the MCC. Look specifically at the sections entitled, “Final
Checklist before Energizing” and “Energizing Equipment.” The
remote power source(s) to the motor control center may be
reconnected and the BPS can be placed into service.
IMPORTANT
This cover must be in place for proper operation of
the BPS.
ATTENTION
The BPS cover must be in place for proper operation
of the switch. Should the switch be operated without
this cover in place, a phase-to-phase fault may occur.
ATTENTION
To prevent injury or death to personnel, make sure
that the terminal guard or terminal guard hood is
installed. The terminal guard or hood must be in
place for proper operation of the switch.
