WARNING
• Never connect power supply wiring to the terminal block for remote controller wiring as this could dam-
age the entire system.
• Use only specifi ed 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 fi ts tightly. Incomplete connections could result in overheating and, in worse case, result in
electric shock or fi re.
• 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 infi ltration 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 fi ts snugly by arranging the wir-
ings neatly and attaching the service lid fi rmly. 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
wiring do not pass through the same locations outside the unit, separating them by at least 5", otherwise
electrical noise (external static) could cause incorrect operation or breakage.
Use only specifi ed 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 over-
heating, and in worse case, electric shock or fi re.
