Make all other necessary external control connec-
tions to the appropriate terminal blocks located
on the control panel. Insure that all connections
are tightened to the torque specified in Figure 4.
Final Equipment Inspection
Prior to energizing the transfer switch:
a. Remove any debris incurred due to shipment or installation.
DO NOT
use a blower
since debris may become lodged in the electrical and mechanical components and
cause damage. Use of a vacuum is recommended.
b. Verify that all cabled connections are correct and that phase rotation of both
sources match.
c. Check engine start connections and verify the correct connection of all control wires.
d. Check settings of all timers and adjust as necessary. Also adjust any optional acces-
sories as required.
e. Check the integrity of power connections by verifying actual lug torque values as
specified in this manual.
f. Make sure that all covers and barriers are installed and properly fastened.
Functional Test
The functional testing of the transfer switch consists of manual and electrical tests described
in this section. Before proceeding, refer to the information package supplied with the transfer
switch. Read and understand all instructions and review the operation of all accessories provided.
A manual operator handle is provided with the transfer switch for maintenance purposes
only. Manual operation of the switch must be checked before it is operated electrically.
Both power sources
MUST
be disconnected before manual operation of the switch. Insert
the handle and operate the transfer switch between the Normal and Emergency positions.
The transfer switch should operate smoothly without binding. Return the switch to the
Normal position, remove the handle, and return it to the holder provided.
Before starting the electrical operation test,
check the equipment rating nameplate on the
transfer switch to verify the correct system
voltage. An example of the equipment rating
nameplate is shown in Figure 5.
First, close the Normal source circuit breaker.
The phase relays B1, B2, and B3 will pick up
and the LED indicators will be illuminated.
Verify the phase to phase voltages at the
Normal line terminals.
