Do not connect the power conductors to the transfer switch until they are tested. Installing power cables in conduit, cable troughs, and ceiling-suspended hangers often requires considerable force. The pulling of cables can damage insulation and stretch or break the conductor’s strands. For this reason, after the cables are pulled into position, and before they are connected, they should be tested to verify that they are not defective or have been damaged during installation.
Line Connections
Refer to the wiring diagram provided with the transfer switch. All wiring must be made in accordance with the National Electrical Code and local codes.
DANGER
!
De-energize all conductors, open all circuit breakers, and rack out all voltage transformers before making any connections. De-energize any UPS, station battery system, or any similar system providing standby control power. Be sure that the Normal and Emergency line connections are in proper phase rotation. Place the engine generator starting control in the OFF position. Make sure engine generator is not in operation.

What to do if a circuit breaker trips
Lock-Out Relay (optional)
If an optional protective relay (device) is ordered for the normal and/or emergency source circuit breaker, a Lock-Out Relay (LOR) is provided on the appropriate circuit breaker compartment door. The LOR responds to a signal from a protective relay and in turn trips the appropriate circuit breaker. The LOR locks out the circuit breaker until the fault is cleared and the protective relay and LOR has been reset. A red light and orange window shows tripped.
Lock-Out Relay status lights
green=ready to respond red=trip signal sent to CB
Status window black=ready to respond
orange=trip signal sent to CB
