Maintenance
No routine maintenance is required. The motors
are permanently lubricated and all internal gear-
train components are oil-impregnated. Careful
installation will also ensure long term reliability and
performance.
Wiring
Connect the wires to the terminal block and apply 24
VAC (+20%/–15%) power for tri-state operation.

DISENGAGEMENT
LEVER
When the actuator reaches the end of rotation, the
motor is disengaged, and (after about five seconds)
the appropriate LED indicator under the translucent
cover illuminates—green for “power open” (CCW)
or red for “power closed” (CW). The LED remains
on until:
• Power to the terminal is simply removed
• Power is switched to the other terminal, and
the actuator starts turning again in the opposite
direction

Specifications 5b. Alternately, insert a single #8 or #10 self-tapping
screw directly into the non-rotation slot. Tighten
the screw only enough to ensure that the screw
will not come out. There should be a bit a play
between the screw and the sides of the slot to help
prevent binding.
