CHAPTER 2 INSTALLATION
Precautions

Turning Power ON

1. 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.
2. When the system is configured with two or more PIMs, the BUS cable provides 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 switch(es) of other
PIMs are left on. Note, however, that the battery continues to charge even under these
circumstances.
3. Do not turn off the PZ-PW121/PZ-PW126 card on PIM1 to PIM7 when the system is
operating.
(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 card 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) Turn the SW1 switches of all the PZ-PW121/PZ-PW126 cards to ON. First, turn ON PIM1
to PIM7. Then, turn ON PIM0 last of all.
