Installation manual
11
Secure the wiring in the order shown below.
1 Secure the ground wire to the stop valve attachment plate so
that it does not slide.
2 Secure the ground wire to the stop valve attachment plate one
more time along with the electric wiring and the inter-unit wiring.

Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the knock-out hole.
(See figure 4)
When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knock-out hole from
cutting the wires.
 Follow the electric wiring diagram for electrical wiring works.

Form the wires and fix the cover firmly so that the cover may be
fit in properly.
Precautions on wiring of power supply and inter-unit
wiring
 Use a round crimp-style terminal for connection to the power
supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following
instruction.
- 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 below.

Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
 Over-tightening the terminal screws can damage the screws.

See the table below for tightening torques for the terminal
screws.

Refer to the installation manual attached to the indoor unit for
wiring of indoor units, etc.

Attach an earth leakage breaker and fuse to the power supply
line.
(See figure 6)

In wiring, make certain that prescribed wires are used, carry out
complete connections, and fix the wires so that outside forces
are not applied to the terminals.
