FUNCTIONAL TEST (after installation)
After installing the Series 165 automatic transfer switch
perform the following three–part functional test.
1–MANUALOPERATION
ELECTROCUTION – FLASH HAZARD
Do not manually operate the transfer
switch until utility and generator are
disconnected; open circuit breakers.
1. Put both the preferred source circuit breaker a nd the
alternate source circuit breaker feeding the automatic
transfer switch in the OFF position. Verify that ALL
POWER IS OFF ! (Seepage2forhandlelocation.)
2. Grasp the maintenance handle and turn it quickly with
your thumb and fingers to manually operate the transfer
switch. The sw itch should operate smoothly without
binding. If it does not, check for shipping damage or
construction debris.

weight marked P (preferred) and A (alternate)
3. After c hecking t he manual operatio n operate the handle
again quickl y to return the transfer switch to the preferred
positi o n (letter P on the round w ei ght facing you).
2–VOLTAGECHECKS
The Series 165 automatic transfer switch is rated for
nominal 240 V ac at 60 Hz (as stated on the nameplate).
Verify that both your preferred a nd alternate sources are
also 240 V ac nominal, 60 Hz. See the wiring diagram.
3 – ELECTRICAL OPERATION
This procedure checks the electrical operation of the
automatic transfer sw itch. If the actual operation does not
follow t his procedure, c onsult the Troubleshooting section.
PERSONAL INJURY HAZARD
Install front cover before operation.
An electrical system fault could
cause a flash and cause injury.
!
1. Install the enclosure cover and tighten the screws.
2. V erify that the generator battery is connected and that the
generator’s starting c ontrol s are set fo r automatic .

3. Tu rn on the preferred so urce (utili ty) circuit breaker.
4. Tu rn on the al ternate source (generato r) circuit breaker.
5. Veri fy that UTILITY (preferred source) acceptable light is on.
6. V eri fy that the TRANSFER SWITCH on utility (preferred
source) light is o n.
7. This step will start the generator. Press and hold
the
Push to Test button until the GENERATOR (alternate
source) acceptable light comes on and stays on.Then
release the button.
This light indicates that the generator is running and
that its output voltage and frequency are acceptable.
Under t ypical conditions, the light should come on after
about 5 to 10 seconds. If the generator is running and
fails to produce the proper voltage and frequency after
60 seconds then a malfunction has occurred (consult
the Troubleshooting section).
8. About 15 seconds after the GENERATOR (alternate
source) acceptable light comes on, the automa tic
transfer switch transfers the load from the utility to the
generator. The TRANSFER SWITCH on generator
(alternate source) light comes on.
9. The transfer sw itch stays connected to the generator for
5 minutes. Then the load is transferred back tothe utility.
To bypass time delay, press and release
the Push t o Test
button again.
10. After lo ad retransfer to utility, the generator runs 1 mi nute
(without lo ad), then shuts down. The GENERATOR
acceptabl e light goes off indicati ng that generator is off .
This completes t he Fu nctional Test. Proceed to next page.
