7.6 Replacing the OIM
The WebPak 3000 Operator Interface Module kit (M/N 925WK0101) is used to replace
the drive’s built-in keypad and display. If necessary, the entire
OIM (P/N 807313-2R) or
the OIM circuit board (P/N 179233) can be replaced using this procedure.
7.6.1 Preparing to Replace the OIM
Before replacing the OIM , disconnect power from the drive.
You will need the following tools:
• #1 Phillips screwdriver
• #2 Phillips screwdriver
• M7 Hex wrench or socket wrench
7.6.2 Accessing the OIM and Disconnecting It from the Regulator Board
These steps are required for both OIM circuit board and complete OIM replacement.
Important: Unless otherwise indicated, keep all hardware for the replacement
procedure.
Step 1. Loosen the screws that secure the front cover to the drive.
Step 2. Remove the front cover.
Step 3. Disconnect the communication cable from J9 on the Regulator board by
pressing down the locking clip and pulling the cable out.
Step 4. Remove the four screws holding the OIM assembly to the drive enclosure.
Step 5. Pull the OIM assembly away from the drive so you can access the ground
wire on the upper right corner of the OIM mounting plate. Slide the ground
wire off its connection.
Important: Ground wires on older versions of the OIM are fastened by a nut. If you are
replacing an older version, keep the hardware so you can re-attach the
ground wire.
7.6.3 Replacing the OIM Circuit Board Only
Follow this procedure if you are replacing only the circuit board. If you are replacing
the entire
OIM assembly, see section 7.6.4, “Replacing the Entire OIM Assembly”.
