4.Wiring Specifications

Use 2-core with no polar wire.

Match the length of wire to wire length of the central control system. If mixed in the SMMS system, the wire length is lengthened with all indoor/outdoor inter-unit wire length at side.

To prevent noise trouble, use 2-core shield wire.

No. of wires

Size

2Up to 1000m: twisted wire 1.25mm2

Up to 2000m: twisted wire 2.0mm2

Connect the shield wire by closed-end connection and apply open process (insulating process) to the last terminal. Ground the earth wire to 1 point at indoor unit side. (In case of central controlling of digital inverter (DI, SDI) unit setup)

CAUTION

1)Closed-end connection of shield wire (Connect all the connecting parts of each indoor unit)

2)Apply open process to the last terminal (insulating process).
