Checking for Supply Voltage
Heat Run Test
Turn the SW1 switch ON. Keep it on for 5 minutes to check for no abnormal voltage. After com-
pleting the test, turn OFF the SW1 switch of the PZ-PW121 card on PIM0. Then, turn OFF the
SW1 switches of all the PZ-PW121 cards.
Before connecting AC Cord, verify:
- that the SW1 switch of the PZ-PW121 card is positioned to OFF;
- that the AC...
