PRECAUTIONS
Precaution for wiring on site
Do not clamp remote controller cords together with wires connecting the units together. Doing so may cause malfunction.
Remote controller cords and wires connecting the units should be located at least 50 mm from other electric
wires. Failure to follow this guideline may result in malfunction due to electrical noise. Read the notes mentioned
below when wiring to the power supply terminal block. Precautions to be taken for power supply wiring. (Use a
round crimp-style terminal for connection to the power supply terminal block. In case it cannot be used due to
unavoidable reasons, be sure to observe the following instructions.)
Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection may
cause overheating.)
When connecting wires of the same gauge, connect them according to the figure.
Make certain that prescribed wires are used, carry out complete connections, and secure the wires so that
outside forces are not applied to the terminals.
CAUTION
After connecting the wires, be sure that no pressure is applied to the wire connections by using cable ties (field
supplied) and securing them to the anchor points. Also, when wiring, make sure the cover of the terminal box fits
snugly by arranging the wires neatly and attaching the terminal box cover firmly. When attaching the terminal box
cover, make sure no wires get caught under the edges.
Make sure the remote control cord, the wiring between the electrical boxes, and other electrical wiring do not pass
through the same locations outside the unit, separating them by at least 50 mm, otherwise electrical noise
(external static) could cause interference to the control system.
All field supplied parts and materials and electric works must conform to local codes. (ie. AS / NZS 3000)
Use copper wire only.
For electric wiring work, refer also to the "WIRING DIAGRAM" label attached to the electrical box cover.
For remote controller wiring details, refer to this installation manual.
All wiring must be performed by an authorised electrician in accordance with local codes. (ie. AS / NZS 3000)
Acircuit breaker capable of shutting down power supply to the entire system must be installed.
Ensure that the air conditioner and zone controller box are effectively earthed.
