Fix to the indicated plastic clamps using field supplied
clamping material

Care should be taken for connecting the wires to the terminal block.
See the table below for the tightening torque of the transmission
wiring terminals.
Never connect the power supply to transmission wiring terminal
block. Otherwise the entire system may break down.
Be careful about polarity of the transmission wiring.
Power supply
The power supply must be clamped to the plastic clamp using field
supplied clamp material.
The green and yellow striped wire must be used for earthing only
(refer to the figure below).

When connecting the earth wire, it is recommended to
perform curling.
NOTICE
When routing earth wires, secure clearance of 25 mm
or more away from compressor lead wires. Failure to
observe this instruction properly may adversely affect
correct operation of other units connected to the same
earth.
When connecting the power supply, the earth
connection must be made before the current-carrying
connections are established. When disconnecting the
power supply, the current-carrying connections must
be separated before the earth connection is. The length
of the conductors between the power supply stress relief
and the terminal block itself must be as such that the
current-carrying wires are tautened before the earth wire
is in case the power supply is pulled loose from the
stress relief.
NOTICE
Precautions when laying power wiring:
Do not connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
When connecting wiring which is the same thickness,
do as shown in the figure below.
For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure being
exerted on the terminal board.
Use an appropriate screwdriver for tightening the terminal
screws. A screwdriver with a small head will damage
the head and make proper tightening impossible.
Over-tightening the terminal screws may break them.
See the table below for tightening torque for the
terminal screws.

NOTICE
Recommendations when connecting the earth wire
Wire it so that it comes through the cut out section of the
cup washer. (An improper earth connection may prevent a
good earthing from being achieved.) (See the figure below.)
Be sure to use crimp-style terminal with insulating
sleeves for connections. (See the figure below.)
