ELECTRIC WIRING WORK
8-1
GENERAL INSTRUCTIONS
• All field supplied parts and materials, electric works must
conform to local codes.
• Specifications for local wiring are in compliance with IEC60245.
• Use copper wire only.
• Follow the “WIRING DIAGRAM” attached to the unitbody to
wire the outdoor unit, indoor units and the remote controller.
For details on hooking up the remote controller, refer to the
“INSTALLATION MANUAL OF REMOTE CONTROLLER.”
• All wiring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B . . . , and be sure the terminal
board wiring to the outdoor unit and BEV unit are properly
matched. If wiring and piping between the outdoor unit and
an indoor unit are mismatched, the system may cause a mal-
function.
• A circuit breaker capable of shutting down the power supply
to the entire system must be installed.

HOW TO CONNECT WIRINGS
• Lower the electric parts box, as shown in the drawing, to
make connections.
CAUTION
• After wiring, adhere the sealing material (35mm × 150mm)
around the wires as shown below.
[Be sure to adhere it to avoid water from outside unit.]
CAUTION
• When clamping the wires, be sure no pressure is applied to
the wire connections by using the included clamping material
to make appropriate clamps. Also, when wiring, make sure
the lid on the electric parts box fits snugly by arranging the
wires neatly and attaching the electric parts box lid firmly.
When attaching the electric parts box lid, make sure no wires
get caught in the edges. Pass wiring through the wiring
through holes to prevent damage to them.
• Make sure the remote controller wiring, the wiring between
the units, and other electrical wiring do not pass through the
same locations outside of the unit, separating them by at
least 50mm, otherwise electrical noise (external static) could
cause mistaken operation or breakage.

Note) Wrap it around the wire
without leaving any space
Be sure to attach it to prevent the infiltration of water as well as
any insects and other small creatures from outside.
Otherwise a short-circuit may occur inside the electric parts box.
