Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal block.
When none are available, follow the instructions below.
• 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 block.
• Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a
small head will strip the head and make proper tighterning impossible.
• Over-tightening the terminal screws may break them.

• Use the cord clamper to fix the cord.
The connecting cable
connected to the indoor and outdoor unit should be complied
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 40 m, connect the
telecommunication line and power line separately.
