CEP-4703/4703V 3 Installation Guide
Wiring Connections
1. Loosen the screw on the conduit ing and lift up
to remove the ing.
2. Using a utility knife or drill, cut the red plug
to accept wiring or replace the plug with an
application-specic ing.
NOTE: The red plug (or similar ing) protects
internal components from debris, helping to
ensure long actuator life.
3. Thread wires through the plugged opening and
connect to the terminal block as shown.
4. Reinstall the conduit ing and tighten the screw.
Operation
After the mechanical and electrical installations have
been completed, cycle the actuator to verify the di-
rection of rotation for normal operation.
When the CEP-4703/4703V is connected to power:
1. The actuator drives to the fully closed position
(for two minutes). If the Override signal is pres-
ent (contact closed across two terminals), indicat-
ing system On, the actuator waits one more min-
ute and then starts controlling. If the Override

2. Whenever the system goes O, the actuator
stores its current position and then drives to the
fully closed position.
3. Whenever the system goes On, the actuator re-
turns to its previous (stored) position, waits one
minute, and resumes controlling.
When controlling, the CEP-4703/4703V control se-
quence is as shown in the diagram.
