    To reduce the risk of fire or explosion, do not place flammable materials or use flammable sprays around the controller. To reduce the risk of electric shock or malfunction, do not touch the switches or buttons with a sharp object. To reduce the risk of injury, electric shock, or malfunction, avoid contact with the sharp edges of certain parts.

  • Page 4: Precautions For Relocating Or Repairing The Unit

    Electrical work must be performed by qualified personnel in accordance with local regulations and the instructions provided in this manual. Only use specified cables and dedicated circuits. Inadequate power source capacity or improper electrical work will result in electric shock, malfunction, or fire. To reduce the risk of electric shock, install an overcurrent breaker and an earth leakage breaker on the power supply.
