Replacing the IB2 (Controller Interface Board) or Optional EIB (Controller Extended Interface Board)
Procedure
NOTE!
Refer to Figure 5.5, Figure 5.6, or Figure 5.7 for circuit card locations. Refer to Figure 5.9 or Figure 5.10 as this
procedure is performed.
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.
WARNING!
Damage to the circuit card may result if the next step is not followed.
2.
Connect an approved grounding strap to your wrist. Attach the other end to a suitable ground.
3.
Open the distribution cabinet’s front door.
4.
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 5.9 or Figure 5.10.
5.
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 5.9 or Figure 5.10.
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.
6.
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.
7.
Unplug all connectors plugged into the circuit card.
8.
Remove the circuit card (and shield) from the distribution cabinet by removing the screws securing it to the cabinet. See
Figure 5.9 or Figure 5.10.
9.
In this step, ensure you do not intermix the old and replacement circuit cards. Set the switch on the replacement circuit card
to the same setting as the old circuit card. Switch settings are documented in the “Setting Jumper and Switch Options”
section of the Power System Installation Instructions (IM582137100).
10.
Secure the replacement circuit card (and shield) to the distribution cabinet. See Figure 5.9 or Figure 5.10.
11.
Plug all connectors removed from the old circuit card into the same position on the replacement circuit card.
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.
12.
Reconnect the external wiring to the correct terminals on the customer connection terminal block. First remove the electrical
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.
13.
Remove the grounding wrist strap.
14.
Close the distribution cabinet’s front door.
