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 Cord is unplugged from the wall outlet.
• Use a tester to verify that the input power is AC120±10V or AC240±10V.
• Plug the AC cord into a wall outlet.
• Turn the SW1 switches of all the PZ-PW121 cards on PIM1 to PIM7 to
ON. Then, turn the SW1 switch of the PZ-PW121 card on PIM0 to ON
last of all.
• Verify that the ON lamp on the PZ-PW121 card lights up.
• Measure the output voltage: -20V should be observed at GND and -27V
terminals of the PZ-PW121 card. See
Figure 2-36
