6.Reinstall the rear PDCA bezel.

CAUTION: Do not measure voltages with the PDCA breaker set to ON. Make sure the electrical panel breaker is ON and the PDCA breaker is OFF.

7.Plug in the PDCA connector.

8.Check the voltage at the PDCA:

a.Using a T-20 driver, remove the screw on the hinged panel at the top of the PDCA. (Figure 3-29).

b.Using a voltmeter, measure the test points and compare the values to the ranges given in Table 3-3 (page 87) to make sure the voltages conform to the specifications for the PDCA and local electrical specifications.

If the voltage values do not match the specifications, have the customer contact an electrician to troubleshoot the problem.

4-Wire	5-Wire
L2 to L3: 200-240 V	L1 to N: 200-240 V
L2 to L1: 200-240 V	L2 to N: 200-240 V
L1 to L3: 200-240 V	L3 to N: 200-240 V
	N to Ground: 1

1Neutral to ground voltage can vary from millivolts to several volts depending on the distance to the ground/neutral bond at the transformer. Any voltage over 3 V must be investigated by a site preparation or power specialist.
