3-10 LonWorks Module for VTAC 7 Drives
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 4.5 Reconnect the keypad bracket to the keypad support bracket by inserting
the mounting tabs into the slots in the keypad support bracket and tightening
the thumb screw.
Step 4.6 Align the Regulator board’s 26-conductor ribbon cable connector with the
Current Feedback board connector. Press it in until it locks into position.
Step 5. Reassemble the Drive
Step 5.1 Reconnect any wiring that was removed from the Regulator board terminal
strip. Refer to the terminal connections documented in step 3.1 or to the
appropriate instruction manuals for the devices being used.
Step 5.2 NEMA 4X/12 drives only: Before installing the cover, check that the gaskets
on the cover are flat and within the gasket channels.
Step 5.3 Reinstall the cover. Align all cover screws into the heat sink before
tightening any of them.
To maintain the integrity of NEMA 4X/12 drives, sequentially tighten the
cover screws to ensure even compression of the gaskets. Do not exceed
2.2 Nm (20 in-lb) of torque on these screws.
