9 ELECTRIC WORK
WARNING
1.Using the specified wires, ensure to connect the wires, and fix wires securely so that the external strength of the wires do not transmit to the connecting part of the terminals.
Incomplete connection or fixation may cause a fire, etc.
2.Be sure to connect earth wire. (Grounding work)
Do not connect the earth wire to gas pipe, city water pipe, lightning rod, or the earth wire of telephone. Incomplete grounding causes an electric shock.
3.For electric work, strictly follow to the Local Regulation in each country and the Installation Manual, and use an exclusive circuit.
Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.
CAUTION
Be sure to install an earth leakage breaker.
If an earth leakage breaker is not installed, an electric shock may be caused.
REQUIREMENT
•For power supply wiring, strictly conform to the Local Regulation in each country.
