●Change Three-phase Input to Two-phase Input
It is not allowed to change the HV610C series three-phase inverter into two-phase.
Otherwise, it may cause fault or damage to the inverter. This operation must be handed
under HNC technical guidance.
●Lightning Surge Protection
The series inverter has lightning over current protection device, and has certain
self-protection ability against the lightning. In applications where lightning occurs
frequently, the user shall install additional protection devices in front of the inverter.
●
Altitude and Derating Use
Altitude of over 1000m of the region, the heat sink’s cooling effect of the inverter
may turn poorer due to the thin air. Therefore, it needs to derate the inverter for use.
This case please contact our technical advice.
● Some Special Use
If the user needs to use the inverter with the methods other than the recommended
wiring diagram in this manual, such as DC bus, please consult our company.

Cautions of Inverter scrapped
The electrolytic capacitors on the main circuit and the PCB may explode when they
are burnt. Emission of toxic gas may be generated when the plastic parts are burnt.
Processed as industrial waste.
● Adaptable Motor
1) The standard adaptable motor is four-pole squirrel-cage asynchronous induction
motor or permanent magnetic synchronous motor. If such motor is not available, be
sure to select adaptable motors in according to the rated current of the motor.
2) The cooling fan and the rotor shaft of the non-frequency-conversion motor adopt
coaxial connection. When the rotating speed is reduced, the heat sink cooling effect will
be reduced. Therefore, overheating occasions should be retrofitted with a strong
exhaust fan or replace the variable frequency motor.
3) Since the inverter has built-in standard parameters of the adaptable motors, it is
necessary to perform motor parameter identification or modify the default values so as
to comply with the actual values as much as possible, or it may affect the performance
and protective properties.
4)Since short circuit cable or internal circuit of motor may cause alarm,or even machine
explosion,please do insulation and short circuit test before the initial use as well as daily
maintenance.Note
：
be sure to do this test, inverter and tested parts must be all
separated!
