3.2 MANUAL OPERATION
Do NOT manually transfer under load.
Disconnect transfer switch from all power
sources by approved means, such as a main
circuit breaker(s).
A manual HANDLE is shipped with the transfer switch. Manual
operation must be checked BEFORE the transfer switch is oper-
ated electrically. To check manual operation, proceed as follows
(Figure 3.1):
1. Turn the generator’s AUTO-OFF-MANUAL switch to OFF.
2. Turn OFF both NORMAL and STANDBY power supplies to the
transfer switch, with whatever means provided (such as the
main line circuit breakers).
3. Note position of transfer mechanism main contacts by
observing display windows in “A” and “B” in Figure 3.1 as
follows:
Window “A” ON, Window “B” OFF - LOAD terminals (T1, T2,
T3) are connected to NORMAL terminals (N1, N2, N3).
Window “A” OFF, Window “B” ON - LOAD terminals (T1, T2,
T3) are connected to STANDBY terminals (E1, E2, E3).
Do not use excessive force when operating
the transfer switch manually or the manual
handle could be damaged.
3.2.1 TRIP TO NEUTRAL POSITION
Remove handle from the square lug at the upper left corner of the
switch. Insert a screwdriver into the “T” hole and push inward. The
main contact should trip to the neutral position and the word OFF
should appear in both windows “A” and “B”. See Figure 3.2.
