ELECTRICAL CONNECTION

1. Using the specifi ed wires, ensure to
connect the wires, and fi x wires securely so
that the external tension to the wires do not
affect the connecting part of the terminals.
Incomplete connection or fi xation may cause a
fi re, etc.
2. Be sure to connect earth wire. (grounding
work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes,
water pipes, lightning rods or ground wires for
telephone wires.
3. Appliance shall be installed in accordance
with national wiring regulations.
Capacity shortage of power circuit or
incomplete installation may cause an electric
shock or a fi re.
• For communication line, use wires with
the same type and size. If each wire has a
different type and size from another one,
it will cause a communication trouble.
• If incorrect / incomplete wiring is carried out,
it will cause an electrical fi re or smoke.
• Install an earth leakage breaker that is not
tripped by shock waves.
If an earth leakage breaker is not installed,
an electric shock may be caused.
• Use the cord clamps attached to the product.
• Do not damage or scratch the conductive core
and inner insulator of power and control wires
when peeling them.
• Use the power supply wire and control wires
of specifi ed thickness, type, and protective
devices required.
• Do not connect 208-240V power to the
terminal blocks (Uv (U1)), (Uv (U2)), (A), (B)
for control wiring. (Otherwise, the system will
fail.)
• Perform the electric wiring so that it does not
come to contact with the high-temperature part
of the pipe.
The coating may melt resulting in an accident.
