3.8.1. 3.8.1 General cautions for electric wiring
ㆍ Check that the power supply is in accordance with the specification on the
name plate (AC230V/50Hz).
Incorrect supply voltage can cause fire.
ㆍ Use an independent power receptacle, safe from rain and moisture.
ㆍ Do not connect ground cable to a lightening arrestor or fuel pipe.
Otherwise, the product may fail or even exploded.
ㆍ Boilers must be grounded to prevent electric shock or other accident by
leakage current.
ㆍ For the 230V power supply, grounding and cable works, observe the
applicable laws and regulations.
ㆍ If the 230V power supply is obtained by individual voltage raise in a 110V
region, make sure to provide a ground connection.
In this case, the capacity of the voltage step up transformer must be at least
1kW.
ㆍ Power receptacle must be away from the boiler by at least 300 mm.
ㆍ The grounding point must be at 300 mm or deeper in the ground.
