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)If any of the low voltage disconnect contactors is open and it is desired to be closed, push the LVD Inhibit Switch to the UP position momentarily and then leave the switch in the middle (OFF) position.

5)Remove the top and front panels to access the circuit cards at the bottom of the distribution cabinet.

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 4-13or Figure 4-14.

7)Unplug all connectors plugged into the circuit card.

8)Remove the screws securing the circuit card and remove the circuit card from the distribution cabinet.

9)Slide the replacement circuit card into the mounting position inside the distribution cabinet, and secure with the screws removed from the old circuit card.

10)Ensure that the LVD Inhibit Switch is in the middle (OFF) position.

11)Plug all connectors removed from the old circuit card into the same position on the replacement circuit card.

12)Push the LVD Inhibit Switch to the down (ON) position.

13)Remove the grounding wrist strap.
