3.1 FUNCTIONAL TESTS AND
ADJUSTMENTS
Following transfer switch installation and intercon-
nection, inspect the entire installation carefully. A
competent, qualified electrician should inspect it.
The installation should comply strictly with all appli-
cable codes, standards, and regulations. When abso-
lutely certain the installation is proper and correct,
complete a functional test of the system.

Perform functional tests in the exact order
presented in this manual, or damage could be
done to the switch.
IMPORTANT: Before proceeding with functional tests, read and
make sure all instructions and information in this section are under-
stood. Also read the information and instructions of labels and decals
affixed to the switch. Note any options or accessories that might be
installed and review their operation.

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 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 (service disconnect circuit breaker) and
GENERATOR (generator main line circuit breaker) power sup-
plies 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.
3.2.1 CLOSE TO UTILITY 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 (UTILITY) position, no further
action is required. If the handle is DOWN, proceed with Step 1.
Step 1: With the handle inserted into the moveable contact carrier
arm, move handle UP. 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.
3.2.2 CLOSE TO GENERATOR 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 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.
