Steps 132 through 146 describe how to restore power from the PDC to Series
I and Series II peripheral module frames. Proceed as follows:
If PDC power
returns to the PM frames
does not return to the PM frames step 132
Obtain one of the following capacitor tools:
• 100-W 120-V light bulb screwed into a socket that has bare-ended
twisted wires
• tool number T000655 (CPC number NTA0600512), fitted with a
fuseholder-style connector instead of bare-ended twisted wires for easier
insertion
At the first empty fuse slot in the PDC, connect the leads of the capacitor
charging tool. Connect the leads across the contacts for the fuse holder until
the light dims. (If you use a tool that charges with a fuseholder-style
connector, insert the connector in the slot until the light dims.)
DANGER
Possible equipment damage or extended service interruption
Make sure you use the correct fuses. When you return fuses
to the PDC, make sure that the amperage of the fuses matches
the amperage marked on the PDC.
Remove the capacitor charging tool and immediately insert the correct fuse
holder in the slot.
Repeat steps 133 and 134 for all the LCE talk battery, TME talk battery, and
PDC filter fuse holders. You removed the fuse holders in step 1. When all
fuses return to the PDCs, continue with the procedure.
Determine if any alarm-indicating fuses are blown.
Note: The fuse alarm-indicator lamp lights when an alarm-indicating fuse
blows.
If alarm-indicating fuses
are blown
are not blown
Locate a fuse holder with a blown alarm-indicating fuse.
Note: Replace blown fuses in any order.
The cartridge fuse in the fuse holder is blown. Remove the fuse holder from
the PDC.
