● Observe the following precautions to ensure safety.
(1) Be sure to confirm the name and polarity for each terminal before performing wiring.
Incorrect wiring may result in burning of or other damage to internal components.
(2) Use a power supply within the specified voltage range.
Use the product within the rated load.
(3) Tighten the screws on the terminal block securely.
The recommended tightening torque is 0.43 to 0.58 N·m.
Loose screws may result in product failure or malfunction.
(4) Do not connect anything to unused terminals.
(5) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.
(6) Output turns OFF when the mode is changed or settings are initialized. Take this into
consideration when setting up the control system.
(7) Install an external switch or circuit breaker and label them clearly so that the operator can
quickly turn OFF the power.
● General Precautions
(1) Do not use the product in the following locations.
• Locations subject to direct radiant heat from heating equipment
• Locations where the product may come into contact with water or oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are
present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
(2) Provide sufficient space around the product for heat dissipation.
(3) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.
(4) Allow the product to operate without load for at least 15 minutes after the power is turned
ON.
(5) To prevent static electricity, do not touch the slits or the terminals while the power is
turned ON.
(6) Do not place heavy loads on the product that would cause it to deform or deteriorate.
● Mounting and Wiring
(1) Mount to a panel between 1-mm and 8-mm thick.
(2) Install the product horizontally.
(3) Use crimp terminals appropriate for the screw size (M3).
