WARNING


Before wiring or maintenance, be sure to turn off the power to the product (including the optional devices). Failure
to do so might cause electric shock or device failure.


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.

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.


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 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 4 to 20 mA input type, make sure the polarity of the power supply and 2 to 10 V DC feedback output
referring to the wiring diagrams. Incorrect wiring might result in PCB (print circuit board) burnout.

To prevent damage, cover the terminals except when connecting/disconnecting wires.

Do not connect 24 V AC power to the terminals 4 to 7. (Max. applicable voltage: 5 V DC)

To keep NEMA 4X and IP54 protection
Use a water-proof connector for the ACTIVAL in a high-humidity environment or outdoor location.

Be sure to completely close the terminal cover and the top cover.

Waterproof the wiring port.
- For cable connection, use a water-proof connector. (Seal connector Part No. 83104346-003 is recommended.)
- For conduit connection, use a water-proof plica tube or the like.
