• Precautions
(1) When the operating power is being supplied to the PZ-PW135 card, do not plug/unplug this
circuit card into/from its mounting slot.
(2) Immediately follow the instructions below if the MJ lamp on the PZ-PW135 lights up or smoke
or a nasty smell is produced during the test:
a)
Turn power off of all PZ-PW135 cards.
b) Unplug the DC 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.
(3) When the system is configured with two or more PIMs, the BUS cable is providing gang control
for the PZ-PW135 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.
