Functional Test
T he Functional Test consists of three checks: manual op
eration, voltage checks, and electrical operation.
CAUTION: Do these checks in the order
presented to avoid damaging the switch.
Read and understand all instructions on the Composite
Elementary Wiring Diagrams and on labels affixed to the
automatic transfer switch. Note any optional accessories
that are provided with this switch, and review their opera
tion before proceeding.
Manual Operation
A manual operator handle (detachable on
260
through
4000
ampere sizes) is provided on the Transfer Switch for
maintenance purposes only. Manual operation of the
switch must be checked before it is operated electrically.
WARNING:
Do not manually operate the
transfer switch until both power sources are
disconnected: Open both circuit breakers.
1.
Select the appropriate switch amperage size below
and follow the directions for installing the handle:
30
through
150
ampere
Grasp the permanently attached manual handle (left
side of the operator) and turn it with thumb and fin
gers. See Figure
1-5.
260
and
400
ampere
Insert the manual handle into the hole in the shaft,
left side of the operator. See Figure
1-6.
600
and
800
ampere
Attach the manual handle onto the pivot shaft exten
sion, left side of the operator. See Figure
1-7.
1000

4000
ampere
Insert the manual handle into the hole in the rotating
weight. See Figure
1-8.
2.
Move the handle as shown to manually operate the
Transfer Switch. T he switch should operate smoothly
