Electrical Wiring

Selection of size of power supply and interconnecting wires

Precautions for Electrical wiring

Electrical wiring work should be conducted only by authorized personnel.

Do not connect more than three wires to the terminal block. Always use round type crimped terminal lugs with insulated

grip on the ends of the wires.

Use copper conductor only.

Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with less than 2% voltage

drop.)

DANGER OF BODILY INJURY OR DEATH

TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC

CONNECTIONS.

GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.

WARNING!

If the supply cord is damaged, it must be replaced by the manufacturer or itsservice agent or a similar qualified person.

If the fuse of control box is broken, please change it with the type of T25A/450VAC;

If the fuse of control PC board is broken, please change it with the type of T3.15A/250VAC. But for 

YUDA060

, the type

is T6.3A/250VAC.

The wiring method should be in line with the local wiring standard.

The power cable and connecting cable should be self-provided.

All the cables shall have got the European authentication certificate. During installation, when the connecting cables

break off, it must be assured that the grouding wire is the last one to be broken off.

The breaker of the air conditioner should be all-pole switch; and the distance between its two contacts should not be no

less than 3mm. Such means for disconnection must be incorporation in the fixed wiring.

The distance between its two terminal blocks of indoor unit and outdoor unit should not be over 5m. If exceeded, the

diameter of the wire should be enlarged according to the local wiring standard.

A leakage breaker must  be installed.
