• Be sure to connect control cables to the indoor
unit, remote controller and the outdoor unit.
• Perform wiring in compliance with the safety
regulations detailed in UL 1995.
• Be sure to install an earth leakage breaker to
the power if required by local codes.
• Ensure that there is no slack on all wire con-
nections.
CAUTION
Be sure to ground the unit. Do not connect the
grounding cable to any gas pipe, water pipe,
lightening rod, or telephone earth cable. Incom-
plete grounding may cause a risk of electrical
shock.
If the supply cord is damaged, it must be re-
placed by the manufacturer, its service agent or
similarly qualified persons in order to avoid a haz-
ard.
External I/O specifications
CAUTION
Wiring should be covered by insulation tube with
supplementary insulation.
Use relays or switches with IEC or equivalent
standard.
The electric strength between accessible parts
and control circuit should have 2750 V or more.
Wiring
Electrical wiring to the air handler will come from the
outdoor unit. Please refer to the installation instruc-
tions for the outdoor unit.
CAUTION
DO NOT POWER THE ELECTRIC HEAT FROM
THE OUTDOOR UNIT. FOLLOW THE APPRO-
PRIATE WIRING SCHEMATIC FOUND IN THE
ELECTRIC HEATER INSTRUCTIONS.
Specifications are subject to change without notice.

13.1. Remote controllers
Connecting remote controller, indoor and out-
door transmission cables
Connect the "1" and "2" on the indoor unit TB15 to a
remote controller. (Non-polarized 2-wire)
NOTE
Ensure that the wiring is not pinched when fitting
the terminal box cover. Pinching the wiring may
cut it.
CAUTION
Install wiring so that it is not tight and under ten-
sion. Wiring under tension may break or overheat
and burn. Fix power source wiring to control box
by using buffer bushing or tensile force. (PG con-
nection or the like.) Connect transmission wiring
to transmission terminal block through the knock-
out hole of control box using ordinary bushing.
CAUTION
Do not use anything other than the correct ca-
pacity breaker and fuse. Using fuse, wire or cop-
per wire with too large capacity may cause a risk
of malfunction or fire.
After wiring is complete, make sure again that there
is no tension on the connections, and attach the
cover onto the control box in the reverse order re-
moval. Also, seal any openings created from wiring
into the air handler. This will prevent air leakage.
CAUTION
Wire the power supply so that no tension is im-
parted. Otherwise disconnection, heating or fire
may result.
IMPORTANT
Attach shielding ground on the outdoor unit's
ground terminal.
