3.2 MANUAL OPERATION

Do NOT manually transfer under load.
Disconnect transfer switch from all power
sources by approved means, such as the 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. Put the generator into the OFF mode.
2. Turn OFF both UTILITY (service disconnect circuit breaker)
and GENERATOR (generator main line circuit breaker) power
supplies to the transfer switch.
3. Note position of transfer mechanism main contacts by
observing the moveable contact carrier arm. This can be
viewed through the long narrow slot in the inside cover of the
ATS. The top of the moveable contact carrier arm is yellow to
be easily identified.
• Manual operation handle in the UP position - LOAD terminals
(T1, T2) are connected to UTILITY terminals (N1, N2).
• Manual operation handle in the DOWN position - LOAD termi-
nals (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.

carrier arm. Return handle to storage bracket.
3.2.2 CLOSE TO GENERATOR SOURCE SIDE
Before proceeding, verify the position of the switch by observ-
ing the position of the manual operation handle in Figure 3.1. If
the handle is DOWN, the contacts are closed in the GENERATOR
(STANDBY) position. No further action is required. If the handle is
UP, proceed with Step 1.
Step 1: With the handle inserted into the moveable contact carrier
arm, move the handle DOWN. Be sure to hold on to the
handle as it will move quickly after the center of travel.
Step 2: Remove manual operating handle from moveable contact
carrier arm. Return handle to storage bracket.
