WIRING PRECAUTIONS
• Make sure to cut off all phases of the power supply externally before attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
• Make sure to attach the terminal cover, offered as an accessory, before turning on the power or initiating operation
after installation or wiring work.
Failure to do so may cause electric shock.
• Make sure to properly wire to the European terminal board in accordance with the following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or damage to the product.
- The disposal size of the cable end should follow the dimensions described in this manual.
- Tightening torque should be between 0.22 and 0.25 N
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires of unspecified size.
