Warning:
Be sure to use specified cables and connect them firmly so that no external
wiring force is exerted on terminal connections. Loose connections may cause
heat or fire.
Caution:
• Some installation sites may required installation of an earth leakage
breaker. Failure to install it may result in an electric shock.
• Always use an earth leakage breaker and fuse with the specified capac-
ity. Use of a fuse with a capacity larger than that specified, or use of a
piece of wire or copper wire may cause breakdown or fire.
