Wiring
Remove actuator cover and ensure power supply
voltage matches the nameplate or label, and that
power supply is capable of providing the stated full
load current.
Two conduit entries are provided on each actuator;
one for power and the other for control signal.
A minimum of 18AWG wiring is recommended for all
field wiring.
Wiring diagram showing terminations is provided in
each actuator.
The actuator should be wired and grounded in
accordance with local and national electrical codes.
Conduit should be sealed at the actuator housing to
prevent water or moisture from entering the actuator
through the conduit openings.
The compartment heater should be continuously
energized to reduce accumulation of moisture
withing actuator housing.
Unused conduit entries must be closed off with plug
fitting approved for use per actuator enclosure
ratings.
CAUTION:
Each actuator must have its own independent
control contact. Actuators wired in parallel will
not operate properly and doing so may cause
damage to the actuator.
Terminals in -690 actuator accept maximum wire
size of 16AWG. Terminals in -1350 thru -25900 size
actuators accept maximum wire size of 14AWG.
Press in spring clamp with small flat head
screwdriver to open terminal for wiring.

counterclockwise and then de-energize when the OLS
cam trips the open position limit switch.
Electrically operate the actuator to the fully Close (CW)
position. The motor should rotate the actuator clockwise
and then de-energize when the CLS cam trips the close
position limit switch.
