AC Line Voltage Test

120 VAC, 50/60 Hz

240 VAC, 50/60 Hz
Revision B
Maintenance: Domestic Electrical Safety Tests
This test verifies that the domestic wall outlet supplying power to the
equipment is properly wired. For international wiring tests, refer to the
internal standards agencies of that particular country.
Use a digital voltmeter to check the voltages of the 120-volt AC wall
outlet (dedicated circuit recommended). If the measurements are
significantly out of range, have a qualified electrician repair the outlet.
The voltage measurements should be as follows:
1. 120 VAC (± 10 VAC) between the line contact and neutral and
between the line contact and ground.
2. Less than 3 VAC between neutral and ground.
NEUTRAL
Use a digital voltmeter, set to measure at least 300 VAC, to check the
voltages of the NEMA 6-20R, AC wall outlet (dedicated circuit
recommended). If the measurements are significantly out of range, have
a qualified electrician repair the outlet. The voltage measurements
should be as follows:
1. 120 VAC (± 10 VAC) between either "hot" contact and ground.
2. 210 to 230 VAC between the two "hot" contacts.
