Wiring
WARNING
Detach the cover only when wiring, setting the product or maintenance and reattach the cover after wiring, setting the
product or maintenance. Failure to do so might cause electric shock.
Before wiring or maintenance, be sure to turn off the power to the product. Failure to do so might cause electric shock
or device failure.
CAUTION
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
All wiring must comply with applicable codes and ordinances.
Provide circuit breaker/fuse protection when powering this product.
Provide a circuit protector (e.g., a fuse, circuit breaker) for the control panel to ensure your safety.
For wiring, strip each wire insulation as specified in this manual. If the strip length is longer than the specified, the
stripped part of the wires might be exposed, causing electric shock or short circuit between adjacent terminals. If it is
shorter, the stripped part might not contact the connector.
Use crimp terminals with insulation for connections to the product terminals. Failure to do so might cause short circuit
leading to fire or device failure.
Firmly tighten the terminal screws. Insufficient tightening of the terminal screws might cause fire or overheating.
IMPORTANT:
The product 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 product.
To prevent damage, cover the terminals except when connecting/disconnecting wires.
Do not leave any refuse including metal chips inside the actuator after cutting a knockout and after connecting
the wires.
Wiring procedure
1) To lead the wires into the terminals, open a knockout for a wiring port. Two knockouts are provided on the bilateral sides of
the actuator terminals. Select a knockout according to the conduit mounting direction, and open the hole by lightly knocking
the knockout using a screwdriver.
2) Unscrew the 3 setscrews (M4
10) of the terminal cover and remove the terminal cover, as shown in Fig. 9.
