Step 3.3 Spread the retaining clips on the Regulator board ribbon cable (on the right
side) to disconnect it from the Base Board.
Step 3.4 Remove the keypad bracket. Place it with the keypad down on a flat surface.
If you cannot lay it flat, tie it up to prevent damage to wiring.
Step 4. Install the LonWorks Module in the Keypad Bracket
Refer to figure 3.6 for component locations.
Step 4.1 Remove the LonWorks module from its anti-static wrapper. Align the key on
the Regulator board’s 34-conductor ribbon cable connector with the slot in
the LonWorks module’s connector. Press the ribbon cable connector in until
it locks into position.
Step 4.2 Route the other ribbon cable out of the side of the keypad bracket.
Step 4.3 Align the LonWorks module on the four mounting tabs on the keypad
bracket. Make sure that the ribbon cable is not pinched between the keypad
bracket and the LonWorks module.
Step 4.4 Fasten the LonWorks module to the right side of the keypad bracket using
the two metal M3 screws and lock washers for proper grounding. Fasten the
left side using the two 6-32 screws and lock washers for proper grounding.
Important: You must use the lock washers to properly ground the LonWorks module.
Improper grounding of the LonWorks module can result in erratic
operation of the drive.
Step 5. Reinstall the Keypad Bracket in the Drive
Step 5.1 Place the keypad support bracket back into position. Use a magnetic
screwdriver to fasten it to the drive with the screws removed in step 3.2.

the slot in the keypad support bracket. Carefully press the ribbon cable
connector in until the retaining clips lock into place.
