electrical connection are satisfied.
Supply and Power Requirements Procedure
It is the installer’s responsibility to provide power supply wiring to the mains supply terminal strip of the outdoor unit.
Make sure all wiring are in accordance with local wiring rules. Wiring should conform to all current electrical authority
regulations and all wiring connections to be as per electrical diagram provided with the unit.
• Confirm that the power supply available is compatible with the unit nameplate ratings. The supply power must be
230V/400VAC(+/- 6%)/50Hz.
• Protect electrical service from over current and short circuit conditions in accordance with AS/NZS 3000
“Australian / New Zealand Wiring Rules”. Size protection devices according to the electrical data of the unit and the

Main Voltage Balance Requirement
Check the voltage at the mains supply terminals to determine if it is balanced. Voltage imbalance on three phase
systems can cause motor overheating and premature failure. The maximum allowable imbalance is + 2.0%, should
voltage imbalance exceed this value, check unit wiring connections to locate and rectify faults or contact local supply
authority.
