Before Installing (Relocating) the Unit or Performing Electric Work
Ground the unit.
• Do not connect the grounding on the unit to gas
pipes,water pipes, lightning rods, or the grounding
terminals of telephones. Improper grounding presents
a risk of electric shock, smoke, fire, explosion, or the
noise caused by improper grounding may cause the
unit to malfunction.
Make sure the wires are not subject to tension.
• If the wires are too taut, they may break or generate
heat and/or smoke and cause fire or explosion.
Install a breaker for current leakage at the power source
to avoid the risk of electric shock.
• Without a breaker for current leakage, there is a risk
of electric shock, smoke or fire.
Use breakers and fuses (electrical current breaker,
remote switch<switch+Type-B fuse>,molded case circuit
breaker) with a proper current capacity.
• The use of large-capacity fuses, steel wire, or copper
wire may damage the unit or cause smoke or fire.
