SUPPLY VOLTAGE CHECK AND HEAT RUN TEST

AC120 V/240 V Power Supply System

• Precautions
(1) Check the switch position of each PZ-PW121/PZ-PW126 card before turning power on.
- Make sure that the AC120 V/240 V selector switch is positioned to appropriate voltage for
each country (AC120 V or AC240 V).
NOTE: PZ-PW126 card does not have this switch.
- Make sure that the battery mode selector switch is positioned as shown below to match the
kind of battery being used:
(2) When the operating power is being supplied to the PZ-PW121/PZ-PW126 card, do not plug/
unplug this circuit card into/from its mounting slot.
(3) Immediately follow the instructions below if the MJ lamp on the PZ-PW121/PZ-PW126 lights
up or smoke or a nasty smell is produced during the test:
a) Turn power off of all PZ-PW121/PZ-PW126 cards.
b) Unplug the AC code from the wall outlet.
c) Carefully check for causes of the failure occurring.
NOTE: Do not turn power on again until the cause is detected.
(4) When the system is configured with two or more PIMs, the BUS cable is providing gang control
for the PZ-PW121/PZ-PW126 card of PIM0 and other PIMs. Therefore, if the power of PIM0 is
off, no power is supplied to the whole system even when the power switches of other PIMs are
left on. Note, however, that the battery charging is continuing even under these circumstances.
