Maintenance
DANGER

Do not live on the equipment repair and maintenance, or there is a risk
of electric shock!

Turn off the input power for 10 minutes before performing maintenance
and repair on the drive, otherwise the residual charge on the capacitor
will cause harm to people!

Do not carry out maintenance and repair on the drive without
personnel who have been professionally trained, otherwise personal
injury or equipment damage will occur!

All pluggable plug-ins must be unplugged in the case of power failure!

The parameters must be set and checked after replacing the drive.
WARNING

Before performing maintenance work on the drive, make sure that the
motor is disconnected from the drive to prevent the motor from feeding
back power to the drive due to accidental rotation.
1.2 Precaution

Contactor using
If the contactor is installed on the power input side of the inverter, do not make the contactor frequent on-off
operation. The interval between ON and OFF of the contactor should not be less than one hour. Frequent
charging and discharging will reduce the use of capacitors in the inverter life.
If a contactor is installed between the inverter output terminals (U, V, W ) and the motor, make sure that the
inverter is turned on and off when there is no output. Otherwise, the inverter may be damaged.

Lightning impulse protection
Although this series of inverters are equipped with lightning over-current protection device, there is a certain
degree of self-protection for inductive lightning, but for lightning frequent place, customers should also install
lightning protection device in the front of the inverter.

Altitude and derating use
In areas above 1000m above sea level, it is necessary to derate the inverter due to poor air quality due to poor
air quality. In this case, please consult our company.

Power input
The inverter power input should not exceed the operating voltage range specified in this manual. If necessary,
use a step-up or step-down device to change the power supply to the specified voltage range.
Do not change the three-phase inverter to two-phase input, otherwise it will cause malfunction or inverter
damage.

Output filtering
When the cable length between the inverter and the motor exceeds 100 meters, it is suggested to use the
output AC reactor to avoid inverter over-current caused by excessive distributed capacitance. Output filter
according to the needs of the field matching.
Inverter output is PWM wave, please do not install the capacitor on the output side to improve the power factor
