Replace the Fuse
CAUTION: Ensure that the power supply module has been disconnected
from the external power source and the module’s On/Off switch has been
set to “0”. Failure to observe this caution could result in damage to, and
subsequent failure of, the power supply module.
NOTE: The power supply module may be “hot swapped” (i.e., serviced while
the chassis is in operation) provided the module to be serviced has been
disconnected from its external power supply and the module’s On/Off
switch has been set to “0”.
To replace the fuse in the CPSMP-130 or CPSMP-140 power supply module:
1. Set the On/Off switch on the power supply module to “0”.
2. Verify that the external power source is NOT powered.
3. Disconnect the positive (+) DC terminal from the external power
connector marked “+”.
4. Disconnect the negative (-) DC terminal from the external power
connector marked “-”.
5. Disconnect the ground terminal from the external power connector
marked “chassis ground”.
6. Rotate the attached panel fastener screw counter-clockwise.
7. Carefully slide the power supply module out of the chassis.
