Precautions for using frequency converter
Date of issue:2015-01-05 15:58:53  see:
When the power supply has been supplied or the frequency converter is in operation, do not open the shell of the frequency converter.
Otherwise, an electric shock may occur.
When the front cover of frequency converter is opened, do not operate the frequency converter.
Otherwise, you may be shocked by the high voltage terminal or the exposed charging capacitor.
In addition to the maintenance or wiring of the frequency converter, do not open the shell of the frequency converter, even if the inverter is not connected to the input power supply.
Otherwise, you may get an electric shock by approaching the charging circuit.
Wiring and periodic inspection should be carried out after removing the input power supply and using the instrument to discharge the DC side voltage (below DC 30V) for at least 10 minutes.
Otherwise, you may get an electric shock.
Turn on the switch with a dry hand.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not make the cable subject to scratch, extrusion, overvoltage and overload.
Otherwise, you may get an electric shock.
The frequency converter should be installed on a non flammable surface, and combustible materials should not be placed nearby.
Otherwise, fire may occur.
If the frequency converter is damaged, disconnect the input power supply immediately.
Otherwise, it may cause secondary damage and fire.
When the input power supply is present or disconnected, the residual heat of the inverter will remain for several minutes.
Otherwise, you may suffer physical injury (e.g. skin burns or injuries).
Do not power up a frequency converter that has been damaged or parts are missing, even if the installation has been completed.
Otherwise, electric shock may occur.
Do not allow linen, paper, sawdust, dust, metal debris or other miscellaneous objects into the inverter.
Otherwise, fire or accident may occur.
