Outside Unit
Electrical Wiring
• Use the 2-core shield cables for transmission lines. Never use them together with power cables.
• The conductive shielding layer of cable should be grounded to the metal part of both units.
• Never use multi-core cable
• As this unit is equipped with an inverter, to install a phase leading capacitor not only will deteriorate
power factor improvement effect, but also may cause capacitor abnormal heating. Therefore, never
install a phase leading capacitor.
• Keep power imbalance within 2% of the supply rating. Large imbalance will shorten the life of the
smoothing capacitor.
• Introducing with a missing N-phase or with a mistaken N-phase will break the equipment.
WARNING
Control Box and Wiring Location
- Unscrew all the screw, pull out the panel.
- Connect the transmission wire between outside unit and indoor
unit, the connection between outside unit and central controller
system pass through the sub PCB for central control.
- When connecting indoor unit with the shield cable, ground at
the grounding screw.
When connecting central controller with the shield cable,
ground at the grounding screw.
- Refer to next page about the distance between main power
cable and communication cable.
- Refer to page 44 for Auto Addressing and page 47 for Test Run
