System Final Test (Continued)
L. PAV / T mode (if installed)
Step 1 Select Mode.
Step 2 Select PAV/T.
Step 3 Activate the PAV/T mode and verify the mode features are displayed on the screen and that
no errors or alarms occur.
NOTE: No further testing of the PAV/T mode is needed since the functioning of the PAV/T
mode is directly linked to the S/T mode through software. The S/T specifications
were verified earlier in the system final test.
Step 4 Turn off the unit, disconnect the test circuit, and remove the power.
Step 5 Install the top enclosure.
M. Earth Resistance
Step 1 Measure and record the earth resistance value. Test current is 25 amps. The value must be
less than 0.10 Ohms (W) to pass.
N. Earth Leakage Current
Step 1 Measure and record the Normal Pole, No Earth, L2 earth leakage current. The value must
be less than 300 microamps to pass.
Step 2 Measure and record the Reverse Pole, No Earth, L2 earth leakage current. The value must
be less than 300 microamps to pass.
Step 3 Measure and record the Reverse Pole, No Earth, No L2 earth leakage current. The value must be less
than 1,000 microamps to pass.
Step 4 Measure and record the Normal Pole, No Earth, No L2 earth leakage current. The value must be less
than 1,000 microcamps amps.
