Voltage Checks
Utility Voltage Checks
1. Turn ON the UTILITY power supply to the transfer switch
with whatever means provided (such as the UTILITY
main line circuit breaker).
2. With an accurate AC voltmeter, check for correct
voltage. Measure across ATS terminal lugs N1 and
N2; N2 and N3; N1 to NEUTRAL, N2 to NEUTRAL,
and N3 to NEUTRAL.
Generator Voltage Checks
1. On the generator panel, select the MANUAL mode of
operation. The generator should crank and start.
2. Let the generator stabilize and warm up at no-load
for at least five minutes.
3. Set the generator main circuit breaker (CB1) to ON
or CLOSED.
4. With an accurate AC voltmeter and frequency
meter, check the no-load, voltage and frequency.
Measure across ATS terminal lugs E1 to E2; E2 to
E3; E1 to NEUTRAL, E2 to NEUTRAL; and E3 to
NEUTRAL. Frequency should be 60–62 Hz.
5. When certain that Three Phase Rotation is correct,
and generator supply voltage is correct and
compatible with transfer switch ratings, turn OFF
the generator supply to the transfer switch.
6. Set the generator main circuit breaker (CB1) to
OFF or OPEN.
7. On the generator panel, select the OFF mode to
shut down the generator.
