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 opera-
tion must be checked BEFORE the transfer switch is operated electri-
cally. To check manual operation, proceed as follows:
1. Put the generator into the OFF mode.
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
the moveable contact carrier arm.
• Manual operation handle towards the top of switch mecha-
nism - LOAD terminals (T1, T2) are connected to UTILITY
terminals (N1, N2).
• Manual operation handle towards the bottom of switch
mechanism - LOAD terminals (T1, T2) are connected to
EMERGENCY terminals (E1, E2).

Do not use excessive force when operating the
transfer switch manually or damage could be
done to the manual handle.
3.2.1 CLOSE TO NORMAL SOURCE SIDE
Before proceeding, verify the position of the switch by observing the
position of manual operation handle in Figure 3.1. If the handle is UP,
the contacts are closed in the NORMAL position, no further action is
required. If the handle is DOWN, proceed with Step 1.
Step 1: With the handle inserted into the actuating shaft, move handle
UP. Be sure to hold on to the handle as it will move quickly
after the center of travel.
3.2.2 CLOSE TO EMERGENCY SOURCE SIDE
Before proceeding, verify the position of the switch by observing the
position of the manual operation handle in Figure 3.1. If the handle
is DOWN, the contacts are closed in the EMERGENCY (STANDBY)
position. No further action is required. If the handle is UP, proceed
with Step 1.
Step 1: With the handle inserted into the actuating shaft, move the
handle DOWN. Be sure to hold on to the handle as it will move
quickly after the center of travel.
3.2.3 RETURN TO NORMAL SOURCE SIDE
