Automatic Transfer Switch Owner’s Manual 9
Section 4 Operation
4.1 — Functional Tests and
Adjustments
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, stan-
dards, and regulations. When absolutely certain the
installation is proper and correct, complete a functional
test of the system.
IMPORTANT: Before proceeding with functional
tests, read and make sure all instructions and infor-
mation in this section is understood. Also read the
information and instructions of labels and decals
affixed to the switch. Note any options or accesso-
ries that might be installed and review their opera-
tion.
4.2 — Manual Operation
A manual handle is shipped with the transfer switch. See
Figure 4-1
. Manual operation must be checked BEFORE
the transfer switch is operated electrically. To check man-
ual operation, proceed as follows:
1.
Verify the 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. This
can be viewed through the long narrow slot in the
inside cover of the ATS. The top of the movable
contact carrier arm is yellow to be easily identified.
• Manual operation handle in the UP position - LOAD
terminals (T1, T2) are connected to UTILITY termi-
nals (N1, N2).
• Manual operation handle in the DOWN position -
LOAD terminals (T1, T2) are connected to
STANDBY terminals (E1, E2).
4.2.1— Transfer Mechanism Manual Operation
Before proceeding, verify the position of the switch by
observing the position of manual operation handle in
Figure 4-1
. 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.
1.
With the handle inserted into the movable contact
carrier arm, move handle UP. Be sure to hold on to
the handle as it will move quickly after the center of
travel.
2.
Remove manual operating handle from movable
contact carrier arm. Return handle to storage
bracket.
