7. Allowable Voltage Range and Power Supply Phase

Make sure the inverter works under allowable voltage range. If necessary, use

boosting transformer or step-down transformer to change the voltage of power

supply. Never change the 3-phase of inverter into 2-phase. Otherwise it will

cause damage to the inverter.

Even there is protection device to protect the inverter from induction thunder

stroke, it's necessary for users in frequent thunder stroke area to install other

protective device.

At an altitude of 1000m or above, it could be better that use the motor with

lower rated capacity. Otherwise the inverter may become overheated because

of rare air. For example, in order to control the motor of 4kW rated capacity, it

could be better to use 5.5kW inverter.

10. Dispose of Scrap Inverter

The scrap capacitor of main circuit and PCB (printed-circuit board) may

explode when it is burned. In order to protect the environment, do not burn

waste plastic parts and scrap capacitor.

The standard matching motor is 4-pole inductive motor. If not, choose the right

matching inverter according to the rated current of the motor.

According to the actual working situation of the motor, the factory setting

of motor standard parameter can be revised. Otherwise it may cause low

efficiency to the unit.
