FUNCTIONAL TEST (after installation)
After installing the Series 165 automatic transfer switch perform the following
1 – MANUAL OPERATION
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 and the alternate source circuit breaker feeding the automatic transfer switch in the OFF position. Verify that ALL POWER IS OFF ! (See page 2 for handle location.)
2.Grasp the maintenance handle and turn it quickly with your thumb and fingers to manually operate the transfer switch. The switch 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 checking the manual operation operate the handle again quickly to return the transfer switch to the preferred position (letter P on the round weight facing you).
2 – VOLTAGE CHECKS
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 and 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 switch. If the actual operation does not follow this procedure, consult 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.Verify that the generator battery is connected and that the generator’s starting controls are set for automatic.

3.Turn on the preferred source (utility) circuit breaker.
4.Turn on the alternate source (generator) circuit breaker.
5.Verify that UTILITY (preferred source) acceptable light is on.
6.Verify that the TRANSFER SWITCH on utility (preferred source) light is on.
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 typical 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 automatic transfer switch transfers the load from the utility to the generator. The TRANSFER SWITCH on generator (alternate source) light comes on.
9.The transfer switch stays connected to the generator for 5 minutes. Then the load is transferred back to the utility. To bypass time delay, press and release the Push to Test button again.
10.After load retransfer to utility, the generator runs 1 minute (without load), then shuts down. The GENERATOR acceptable light goes off indicating that generator is off.
This completes the Functional Test. Proceed to next page.
