terminal board w iring to the outdoor unit and BS unit are
properly matched. If controls w iring and piping bet w een the
outdoor and indoor units are mismatched, a communica-
tions malfunction is likely.
• Install a w iring interrupter or ground-fault circuit interrupter
for the po w er w iring.
• Make sure the ground resistance is no greater than 100
Ω
.
• To avoid short circuiting the po w er supply w ire, be sure to
use insulated terminals.
• Do not turn on the po w er supply ( w iring interrupter or
ground-fault circuit interrupter) until all other w ork is done.
DANGER
• Do not ground units to w ater pipes, telephone w ires or light-
ning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, or
to gas pipes because a gas leak could result in an explo-
sion
w hich could lead to severe injury or death.
9-2 LIST OF STANDARD WIRING EQUIPMENT
NOTE
1. If the w iring is in a place w here people it can be easily
touched, 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.
3. When using a ground-fault circuit interrupter only for
grounding device, make sure to use a w iring interrupter
together.
• The length of the transmission w iring and remote controller
w iring are as follo w s:.

10. WIRING EXAMPLE
10-1 HOW TO CONNECT WIRINGS
• Wire only after removing the control box lid as sho w n in
Fig. 14.
WARNING
• Use only specified w ire and connect w ires to terminals
tightly. Be careful that w ires do not place external stress on
terminals. Keep w ires in neat order so as to not to obstruct
other e q uipment. Make sure that the electric parts box lid
closes tightly. Incomplete connections could result in over-
heating, and in
w orse cases, electric shock or fire.

material (12)
• Make sure to let a wire go through a wire penetration area.
• After wiring, seal the wire and wire penetration area to prevent
moisture and small creatures from the outside.
• Wrap the wire with the sealing material (12) as shown in the figure below.
(Otherwise, moisture or small creatures such as insects from
the outside may cause short-circuit inside the control box.)
Attach securely so that there are no gaps.
