Note: Form 6 Rack Mount Controls with serial numbers below
20,000 and Form 6 Pole and Yard Mount Controls with
serial numbers below 10,000 will need an additional
CPU replacement kit to upgrade a communications
board. Refer to KME6-3837-3S (pole mount) or KME6-
3837-4S (rack/yard mount).
This procedure will be used when changing communica-
tions accessory board:
1. Remove the CPU circuit board. Refer to Form 6
Removal/Replacement of CPU Board section.
2. Remove the TB1 terminal block strip from the back of
the module (Figure 2).
3. Carefully pull the CPU board outward so as not to
damage the capacitor or any of the electrical compo-
nents on the Bezel tabs (Figure 6).
4. Install two standoffs with copper washers into the
holes on the left side of the CPU board (Figure 7).
5. Carefully install the communication board onto the
CPU board so as to not bend any connections.
6. Install two screws with lock washers onto the com-
munications board.
Note: Use 10 in-lbs. of torque. Do not overtighten
standoffs.
