3-18 LonWorks Module for VTAC 7 Drives
Step 4. Install the LonWorks Module in the Keypad Bracket
Refer to figures 3.8 and 3.9 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 support 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 Align the Regulator board ribbon cable connector with the connector to the
Base board. Carefully press the ribbon cable connector in until the retaining
clips lock into place.
Step 5.2 Place the keypad bracket back into position.
Step 5.3 Reattach the anodized inner cover.
Step 5.4 If the drive has:
• A Regulator board cover and a terminal cover: Replace the Regulator board
cover. Fasten it using the three M4 screws removed in earlier.
• Only a terminal cover: Use a long magnetized screwdriver to fasten the four
screws that hold the keypad bracket. Replace the side cover.
Step 5.5 Reconnect any wiring that was removed from the Regulator board terminal
strip. Refer to the terminal connections documented in step 3.4 or to the
appropriate instruction manuals for the devices being used.
