Wiring
CAUTION
Provide a circuit protector (e.g., a fuse or
circuit breaker) for the power source.
Failure to do so may cause a short circuit
leading to fire or device failure.
Install, wire, and use this product under the
conditions specified by this manual.
Failure to do so may cause fire or device
failure.
Installation and wiring of the actuator must
be performed by personnel qualified to do
instrumentation and electrical work.
Mistakes in installation or wiring may cause
fire or electric shock.
Before wiring, be sure to turn off the power to
this product.
Failure to do so may result in electric shock
or device failure.
All wiring must comply with applicable codes
and ordinances.
Otherwise there is a danger of fire.
Use crimp terminals with insulation for
connections to the product terminals.
Failure to do so may cause short circuit
leading to fire or device failure.
Tighten the terminal screws with the specified
torque.
Insufficient tightening of the terminal screws
may cause fire or overheating.
IMPORTANT
•
This product is designed for 24 V AC power supply
voltage.
Do not apply power supply voltage other than 24 V AC.
•
For the 2
–
10 V DC input type and 4
–
20 mA input
type, check the polarity of the power supply and 2
–
10
V DC feedback signal, and then correctly wire the
product. Incorrect wiring may result in PCB (print
circuit board) burnout.

How to maintain IP54 (dust-proof,
splash-proof)
In order to maintain IP54 performance, use a
waterproof connector or a water-resistant plica
tube when the product is used in high humidity
environment or outdoor.
•
Be sure to completely close the terminal cover and
top cover.
•
Apply a waterproofing treatment for the knockout
hole.
•
For cable connection, use the waterproof
connector (to be ordered separately) .
•
For conduit connection, use the waterproof plica
tubes etc.

Wiring procedure
(1) Select a knockout hole according to the wire
outlet direction, and open a knockout hole.
Two knockout holes are provided on the bilateral
sides of the actuator. The knockout holes can be
easily opened by lightly knocking the hole using a
screwdriver.
Knockout hole
IMPORTANT
•
Do not leave pieces of metal (generated by making
the knockout hole) inside the actuator.
(2) Unscrew the 3 setscrews (M4 x 10) on the
terminal cover to remove the cover.
Unscrew the terminal
cover screws.
Remove the
terminal cover.
