Procedure
1. Performing this procedure may activate external alarms. Do one of the following. If possible, disable these alarms. If these
alarms cannot be easily disabled, notify the appropriate personnel to disregard any future alarms associated with this system
while the procedure is being performed.
DANGER! Performing the next steps exposes service personnel to battery potential. Exercise extreme caution not to
inadvertently contact or have any tool inadvertently contact any energized electrical termination.
2. Open the distribution cabinet's front door by turning the latch in the counterclockwise position.
WARNING! Damage to the circuit card may result if the next step is not followed.
3. Connect an approved grounding strap to your wrist. Attach the other end to a suitable ground.
4. Remove the shield to access the circuit cards at the bottom of the distribution cabinet.
5. Carefully label the wires connected to the customer connection terminal blocks on the circuit card. These wires must be
connected to the same terminals on the replacement circuit card. Refer to Figure 5.5 or Figure 5.6.
6. Carefully label the connectors plugged into the circuit card. These connectors must be plugged into the same connectors on
the replacement circuit card. Refer to Figure 5.5 or Figure 5.6.
DANGER! In the next step, external alarm wiring may be energized from an external source. DO NOT allow bare wire ends to
contact any grounded or energized object.
7. Remove the external wiring from the customer connection terminal blocks. DO NOT allow the bare wire end to contact any
grounded or energized object. Isolate the wire end with electrical tape. Repeat for each wire to be removed.
8. Unplug all connectors plugged into the circuit card.
9. Remove the screws securing the circuit card and remove the circuit card from the distribution cabinet.

tape that was applied to the bare wire end in a previous step. DO NOT allow the bare wire end to contact any grounded or
energized object. After securing the wire, gently tug on the wire to ensure that it cannot be pulled out of the terminal block.
Repeat for each wire to be reconnected.
