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:
•
The ACTIVAL is designed for 24 V AC power supply voltage. Do not apply any other power voltage
(e.g., 120 V AC, 240 V AC) to the ACTIVAL.
•
For the 2–10 V DC input type and 4–20 mA input type, check the polarity of the power supply and feedback
signal, and then correctly wire the product.
Incorrect wiring may result in PCB (print circuit board) burnout.
•
To prevent damage, cover the terminals except when connecting/disconnecting wires.
•
Do not leave any refuse including metal chips after cutting a knockout hole and after connecting the wires
inside the actuator.
•
Do not connect 24 V AC power to the terminals 4 to 7.
To keep NEMA 4X, Type 4 Enclosure, and IP54 protection
In order to maintain NEMA 4X, Type 4 Enclosure, and IEC IP54 performance, use waterproof connectors etc. when the
product is used in high humidity environment or outdoor.
•
Close the terminal cover and top cover firmly. (Screw tightening torque: 7.08 lbf•in (0.8 Nm))
•
Apply a waterproofing treatment for the knockout holes. (In order to satisfy the Type 4 Enclosure requirements, use the UL
listed conduit fittings that are equivalent to Type 4 or more stringent.)
•
Use waterproof connectors to pull out the cables. (Seal connector Part No. 83104346-003 is recommended.)
•
If cables are connected by cable glands, use waterproof plica tubes etc.
Wiring precautions
1) To lead the wires into the terminals, cut out a knockout hole for a wiring port. Two knockout holes are provided on the
bilateral sides of the actuator terminals. Select a knockout hole according to the conduit mounting direction, and cut it out
by lightly knocking the hole using a screwdriver.
