Section 3 — Operation

Generac “V” Type and “Y” Type Transfer Switch

3.1FUNCTIONAL TESTS AND

ADJUSTMENTS

Following transfer switch installation and intercon- nection, inspect the entire installation carefully. A competent, qualified electrician should make the inspection.

The installation should comply strictly with all appli- cable codes, standards, laws and regulations. All electrical connections must be correct and in compli- ance with applicable codes and standards.

Make sure the standby generator is ready. This includes checking engine oil level, coolant level, fuel supply, batteries and other items specified in the OWNER'S MANUAL for specific generators.

Complete all functional tests as outlined in the FUNC- TIONAL TESTS section. Do this before placing the transfer switch into service.

3.2FUNCTIONAL TESTS

Following transfer switch installation, the entire standby electric system should be inspected and test- ed. Have all necessary adjustments completed at this time. Functional tests of the transfer switch include these tests: (a) Manual Operation, (b) Voltage Checks and (c) Electric Operation.

To avoid damaging the transfer switch, perform

!functional tests In the exact order given.

Before proceeding with functional tests, read and be sure you understand all instructions in this section. Also, read the instructions and information on tags and decals affixed to the transfer switch. Note any options and accessories that might be installed or provided with the switch and review their operation.

DANGER

DO NOT ATTEMPT MANUAL OPERATION OF THE TRANSFER SWITCH UNTIL AFTER ALL POWER VOLTAGE SUPPLIES TO THE SWITCH HAVE BEEN TURNED OFF. FAILURE TO TURN OFF POWER VOLTAGE SUPPLIES MAY RESULT IN DANGER- OUS AND POSSIBLE FATAL ELECTRICAL SHOCK.

3.3MANUAL OPERATION

The pre-packaged transfer switch has a choice of two transfer mechanisms - the "V" type (Model 9227-0) and the "Y" type (Models 9228, 9229 and 9230).

◆3.3.1 “V” TYPE TRANSFER SWITCHES

Test manual operation for “V” type transfer switches as follows:

1.Check that the generator's Auto/Off/Manual switch has been set to OFF position.

2.Turn OFF the UTILITY power supply to the trans- fer switch, using whatever means provided (such as the UTILITY source main line circuit breaker).

3.Set the generator's main circuit breaker to its OFF or OPEN position.

DANGER

FAILURE TO TURN OFF ALL A POWER VOLTAGE SUPPLIES TO THE TRANSFER SWITCH BEFORE ATTEMPTING MANUAL OPERATION RESULTS IN EXTREMELY HAZARDOUS AND POSSIBLY FATAL ELECTRICAL SHOCK.

4.Remove the manual transfer handle from the enclosure.

5.Place open slot of the manual transfer handle on the small tab of the transfer switch operating lever (Figure 3.1).

6.Pull manual transfer handle downward, then move it back to original position. If handle is down, LOAD is connected to UTILITY power source. If handle is up, LOAD is connected to STANDBY power.

7.Move the transfer switch main contacts to both positions several times. Leave the transfer switch in the UTILITY position and connect LOAD to the UTILITY power source (manual operation lever is up).
