Supply Voltage Check And Heat Run Test

SUPPLY VOLTAGE CHECK AND HEAT RUN TEST

Precautions

(1) Check the switch position of each PZ-PW121/PZ-PW126 card before turning power on.
• Make sure that the AC120V/240V selector switch is positioned to appropriate voltage for
each country (AC120V or AC240V).
NOTE: PZ-PW126 does not have this switch.
• Make sure that the battery mode selector switch is positioned as shown below to meet the
kind of battery:
(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 an unpleasant odor 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 cause(s) 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 PIM 0 and other PIMs. Therefore, if the power
of PIM 0 is off, no power is supplied to the whole system even when the power switch(es)
of other PIMs are left on. Note, however, that the battery charging is continuing even under
these circumstances.
