Application and Installation
Figure 24. Warning and Circuit Active Labels installed on the
Mounting Surface.
Step 2: Final Wiring and Breaker Preparation
Figure 25. Overview: Final Wiring of the RSM, Mode Selector
Switch, Indicator Light, and Battery Holder.
A. Plug the female connector on the mode selector switch bat-
tery harness onto the male receptacle at the back of the bat-
tery holder. Open the battery holder door and install the
battery.
Figure 26. Connecting the Battery Holder to the Mode Selector
Switch Battery Harness.
B. If the breaker was removed from the cell to install the Arc-
flash Reduction Maintenance Switch, temporarily place the
breaker back into the cell.
C. Route the mode selector switch harness from the switch loca-
tion to the RSM making sure it is away from any moving parts
within the breaker. In routing the harness, be sure to leave a
service loop in the harness to facilitate racking the breaker in
to and out of the cell. If the mode selector switch was
mounted to the cell door, also provide a service loop at hinge
to allow the door to fully open and close.
CAUTION
MAKE SURE THE BREAKER IS IN THE RACKED-OUT POSITION AND
REMAINS DE-ENERGIZED UNTIL FINAL WIRING IS COMPLETED.
CAUTION
DO NOT PERFORM ANY MAINTENANCE: INCLUDING BREAKER
CHARGING, CLOSING, TRIPPING, OR ANY OTHER FUNCTION WHICH
COULD CAUSE SIGNIFICANT MOVEMENT OF THE BREAKER WHILE
IT IS ON THE EXTENSION RAILS. DOING SO MAY CAUSE THE
BREAKER TO SLIP FROM THE RAILS AND FALL, POTENTIALLY
CAUSING SEVERE PERSONAL INJURY TO THOSE IN THE VICINITY
.
CAUTION
DO NOT LEAVE THE BREAKER IN AN INTERMEDIATE POSITION IN
THE SWITCHGEAR CELL. ALWAYS LEAVE IT IN THE CONNECTED,
DISCONNECTED, OR (OPTIONAL) TEST POSITION. FAILURE TO DO
SO COULD LEAD TO IMPROPER POSITIONING OF THE BREAKER
AND FLASHOVER, CAUSING DEATH, SERIOUS PERSONAL INJURY,
AND / OR PROPERTY DAMAGE
