The operational voltage range is ±10%, the voltage range where the specified performance is
guaranteed is rating±5%, the frequency is rating±1%.
※
Check line voltage of its receptacle/switch board of facilities and/or whether utilize the same
line with other equipments or not, if this Equipment does not start up/operate even to turn Earth
Leakage Breaker(ELB) On(

). Take correct action for the solution, such as changing its power
source away from other equipment.
Multiple plugs with a branch outlet or extension with the cord reel may cause voltage drop,
resulting in deterioration of the heating capacity or of the temperature control performance.
10. Must connect grounding wire properly.

・
Must connect grounding wire properly to grounding line or terminal in order to avoid
electrical shock due to electrical leakage.
・
Never connect grounding wire to gas line pipe or water line pipe due to fire or electrical
shock.
・
Never connect grounding wire to telephone grounding line or to lightening conductor due to
fire or electrical shock.
・
Never connect multiple plug to single receptacle due to generating heat dangerously.
Connect to grounded receptacle.
