8. Electric wiring

WARNING!

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.

(1)Selection of size of power supply and interconnecting wires. Precautions for Electric wiring

Electric 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.)

If the supply cord is damaged, it must be replaced by the manufacturer or its service 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.

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

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

For AU122AEERA,AU182AFERA, the power cable should be H05RN-F 3G 2.5mm2.

For AU242AGERA, AU282/362AHERA, the power cable should be H05RN-F 3G 4.0mm2 For AU422/522AIERA, the power cable should be H05RN-F 3G 6.0mm2

For AU36NAHERA, AU42NAIERA the power cable should be H07RN-F 5G 2.5mm2 For AU52NAIERA, the power cable should be H07RN-F 5G 4.0mm2.

The connecting cable should be H05RN-F 4G 0.75mm2.

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.
