WIRING
WARNING
Electrical Shock Hazard.
Can cause serious injury or death.
Disconnect power supply before making wiring
connections to prevent electrical shock and equipment
damage.
Wiring must comply with all applicable electrical codes,
ordinances and regulations. Wiring to the actuator must be
NEC Class 1.
Connect the power supply to terminals 1 and 2 on the V4055
terminal strip. Refer to Fig. 4 for Auxiliary Switch connections
and Fig. 5 for Max Flow Limit Switch connections. For typical
system hookups, refer to Fig. 6 and to instructions packed with
the device used to control the valve.
When all wiring connections are complete, replace the actuator
faceplate.
CAUTION
Operation Hazard.
Improper wiring can cause improper and
dangerous operation.
Label all wires prior to disconnection when servicing
valves. Wiring errors can cause improper and
dangerous operation.
NOTE: Pipe sealant is required on the conduit threads of
actuators with NEMA 4 enclosures.
Adjust Auxiliary Switch (If Used)
The Auxiliary Switch is adjustable throughout the stroke of
the actuator. With the switch installed in the actuator, turn
the adjusting screw (see Fig. 2) clockwise to cause the
switch to operate earlier in the stroke or counter-
clockwise to cause the switch to operate later in the
stroke.
