Manual Transfer Operation
Prior to automatic operation, manually exercise the
transfer switch to verify there is no interference with
proper operation of the mechanism. Manual operation of
the transfer switch is required if electronic operation
should fail.
Transfer to Generator Power Source
1. Verify generator is OFF.
2. Set main line circuit breaker (MLCB) (generator
disconnect) to OFF (OPEN).
3. Turn OFF utility power supply to the transfer switch
using the means provided (such as a main line
utility breaker).
4. See Figure 3-11 . Use the manual transfer handle
(A) inside the transfer switch to move the main
contacts to STANDBY (loads connected to the
standby power source).
5. Press control panel MANUAL mode button to crank
and start the engine.
6. Allow engine to stabilize and warm up for a few
minutes.
7. Set MLCB (generator disconnect) to ON
(CLOSED). The standby power source now
powers the loads.
