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 pre-
sented in this manual, or damage to the switch
could be done.
IMPORTANT: Before proceeding with functional tests, read and make
sure you understand all instructions and information in this section.
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.
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. Ensure the generator is in the OFF mode.
2. Turn OFF or OPEN both UTILITY and EMERGENCY power sup-
plies 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) are
connected to utility terminals (N1, N2).
• Window “A” OFF, Window “B” ON - LOAD terminals (T1, T2) are
connected to emergency terminals (E1, E2).
