DANGER
Do not ground units to water piping, telephone wires or
lightning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, nor
to gas piping because a gas leak could result in an explo-
sion which could lead to severe injury or death.

NOTES
1.
If the wiring is in a place where people it can be easily
touched by people, install a ground-fault circuit interrupter
to prevent electric shock.
2.
When using a ground-fault circuit interrupter, make sure to
select one useful also to protection against overcurrent and
short-circuit.
When using a ground-fault circuit interrupter only for
grounding device, make sure to use a wiring interrupter
together.
The length of the transmission wiring and remote controller
wiring are as follows.

HOW TO CONNECT WIRINGS
〈Precautions when laying power supply wiring〉
Wiring of different thicknesses cannot be connected to the
power supply wiring terminal block. Slack in the power
supply wiring may cause abnormal heat.
Use sleeve-insulated round crimp-style terminals for con-
nections to the power supply wiring terminal block. When
none are available, connect wires of the same diameter to
both sides, as shown in the fi gure.

gauge to one side.
If the wiring gets too hot due to loose power-supply wir-
ing, use the following precautions:
For wiring, use the designated power supply wiring and
connect fi rmly, then secure to prevent outside pressure
being exerted on the terminal board.
Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head of
the screw might be damaged, and the screw will not be
properly tightened.
If the terminal screws are tightened too hard, screws might
be damaged.
Refer to Table 4 for the tightening torque of the terminal
screws.
