HNC Electric HV590 Series, User Manual

Page: 9 / 192

●Change Three-phase Input to Two-phase Input
It is not allowed to change the HV590 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 reuduced.
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!
