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.
For wiring, strip the insulation from cables as specified in this manual.
If the length of exposed wire is longer than specified, it may cause electric shock or short circuit between adjacent
terminals.
If it is too short, it may not make proper contact.
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 any other power voltage (e.g., 100 V AC, 200 V AC) to the product.
Do not leave any refuse including metal chips inside the actuator after cutting a knockout hole and after
connecting the wires.
Wiring procedure
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.
2) Unscrew the 3 setscrews (M4
10) of the terminal cover and remove the terminal cover, as shown in Fig. 10.
