Precautions when laying power wiring
- For wiring, use the designated power wire
and connect firmly, then secure to prevent
outside pressure being exerted on the termi-
nal block.
- Use an appropriate screwdriver for tightening
the terinal screws. A screwdriver with a
small head will strip the head and make prop-
er tighterning impossible.
- Over-tightening the terminal screws may
break them.
Use round pressure terminals for connections
to the power terminal block.
When none are available, follow the instruc-
tions below.
- Do not connect wiring of different thickness-
es 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.

CAUTION
The connecting cable connected to the
indoor and outdoor unit should be com-
plied with the following specifications
(Rubber insulation, type H05RN-F
approved by HAR or SAA).
If the supply cord is damaged, it must be
replaced by a special cord or assembly
available from the manufacturer of its
service agent. When the connection line
between the indoor unit and outdooor
unit and outdoor unit is over 40m, con-
nect the telecommunication line and
power line separately.
