KMC Controls MEP-5233 - Manual (Page 2)

Wiring
1. Remove access cover to expose terminal block.
2. Route wires through the grommets in the cover.
3. Provide strain relief to prevent wires from pulling or
snagging.
4. Connect stripped wires to appropriate terminals:
CW (clockwise to close)
COM (common)
CCW (counterclockwise to open)
5. Replace access cover.
6. Install or reposition any insulation (check local codes).
In areas where excessive condensation may occur,
carefully insulate over the actuator assembly. Make sure
the insulation does not interfere with actuator operation.
Adjustments
Once the unit is installed check dampers and verify
operation. When 24 VAC is applied between common and
open the damper should fully open in approximately 15
seconds (18 seconds in 50 hz applications).
If the damper jams or stalls it will not damage the damper
or motor. These problems are usually the result of twisting
or bending of the damper body during installation.
Straightening the damper body usually fixes these
problems.
If it become necessary to force a damper open, press the
gear disengagement button and simultaneously turn the
mounting hub. Release the button to hold the damper in
the new position.
Maintenance
No routine maintenance is required.
The motors are permanently lubricated and all internal
gear-train components are oil-impregnated. Careful
installation will ensure long term reliability and
performance.
