WARNING
•
Never connect power supply wiring to the terminal block for remote controller wiring as this could damage
the entire system.
•
Use only specified wire and connect wires to the terminal tightly. Be careful wires do not place external
stress on terminals. Keep wires in neat order so as not to obstruct other equipment. Make sure that the
electric box lid fits tightly. Incomplete connections could result in overheating and, in worse case, result in
electric shock or fire.
•
To avoid a short circuit in the electric parts box, be sure to apply sealing material or putty (not included) to
the wiring hole to prevent the infiltration of water as well as insects or other small creatures. Otherwise a
short-circuit may occur inside the electric parts box.
CAUTION
•
When clamping the wirings, be sure no tension is applied to the wire connections by using the included
clamp. Also, when wiring, make sure the lid on the electric parts box fits snugly by arranging the wirings
neatly and attaching the service lid firmly. When attaching the service lid, make sure no wirings get caught
in the edges. Pass wiring through holes to prevent damage to them.
•
Make sure the remote controller wiring and transmission wiring between the units, and other electrical wir-
ing do not pass through the same locations outside the unit, separating them by at least 5”, otherwise elec-
trical noise (external static) could cause incorrect operation or breakage.
Use only specified wire and tightly connect wires to terminals. Be careful wires do not place external stress
on terminals. Keep wiring in neat order and so as not to obstruct other equipment such as popping open the
service cover. Make sure the cover closes tight. Incomplete connections could result in overheating, and in
worse case, electric shock or fire.
