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 operated
electrically. To check manual operation, proceed as follows:
1.
Turn the generator's AUTO/OFF/MANUAL switch to OFF.
2.
Turn OFF both UTILITY and EMERGENCY 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 utility terminals (N1, N2, N3).
• Window "A" OFF, Window "B" ON - LOAD terminals (T1, T2,
T3) are connected to emergency terminals (E1, E2, E3).
Figure 3.1 — Actuating Transfer Switch
Do not use excessive force when operating
the transfer switch manually or the manual
handle could be damaged.
3.2.1 CLOSE TO NORMAL SOURCE SIDE
Before proceeding, verify the position of the switch by observing
window "A" in Figure 3.1. If window "A" reads "ON", the contacts
are closed in the normal position, no further action is required. If it
reads "OFF", proceed with Step 1.
Step 1: With the handle attached to the actuating shaft, move
handle in the direction of the arrow on the switch cover
until it stops — DO NOT FORCE. Release handle slowly
to allow the spring in the switch box to relax. "ON" now
appears in Window "A" and "OFF" appears in Window "B".
