Before proceeding, verify the position of the switch by observing the position of the manual operation han- dle in Figure 3.1. If the handle is DOWN, the contacts are closed in the EMERGENCY (STANDBY) position. No further action is required. If the handle is UP, pro- ceed with Step 1.

Step 1: With the handle inserted into the actuating shaft, move the handle DOWN. Be sure to hold on to the handle as it will move quickly after the center of travel.

3.3VOLTAGE CHECKS

1.Turn ON the UTILITY power supply to the trans- fer switch with whatever means provided (such as the UTILITY main line circuit breaker).

DANGER

PROCEED WITH CAUTION. THE TRANSFER SWITCH IS NOW ELECTRICALLY HOT. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY HAZARDOUS AND POSSIBLY FATAL ELECTRI- CAL SHOCK.

2.With an accurate AC voltmeter, check for correct voltage.

Single-phase utility supply:

Measure across ATS terminal lugs N1 and N2. Also check N1 to NEUTRAL and N2 to NEUTRAL.

3.When certain that UTILITY supply voltage is cor- rect and compatible with transfer switch ratings, turn OFF the UTILITY supply to the transfer switch.

4.On the generator panel, set the AUTO-OFF- MANUAL switch to MANUAL position. The gener- ator should crank and start.

5.Let the generator stabilize and warm up at no- load for at least five minutes.

6.Set the generator's main circuit breaker (CB1) to its ON or CLOSED position.
