Section 4: Operation
Functional Tests
Following transfer switch installation and interconnection,
inspect the entire installation carefully. A competent,
qualified electrician should inspect it. The installation
should comply strictly with all applicable codes,
standards, and regulations. When absolutely certain the
installation is proper and correct, complete a functional
test of the system.
IMPORTANT NOTE: Before proceeding with functional
tests, read and make sure all instructions and information
in this section is understood. 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
See Figure 4-1. 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. Verify generator is OFF.
2. Turn OFF both UTILITY (service disconnect circuit
breaker) and STANDBY (generator main line circuit
breaker) power supplies to the transfer switch.
3. Note position of transfer mechanism main contacts
by observing the movable contact carrier arm.
• Manual operation handle in UP position (B)—
LOAD terminals (T1, T2) are connected to
STANDBY terminals (E1, E2).
• Manual operation handle in DOWN position (A)—
LOAD terminals (T1, T2) are connected to UTILITY
terminals (N1, N2).
Transfer Mechanism Manual Operation
Before proceeding, verify switch position by observing
manual operation handle in Figure 4-1. If handle is
DOWN, contacts are closed in the NORMAL (UTILITY)
position and no further action is required. If handle is UP,
proceed with Step 1.
1. With handle inserted into the movable contact car-
rier arm, move handle DOWN. Hold handle
securely, as it will move quickly past center of
travel.
2. Remove manual operating handle from movable
contact carrier arm. Return handle to storage
bracket.
