4. Wiring
In order to ensure the safety operation of inverter, it must be
connected by licensed electric technicians.
It is forbidden to use high voltage insulation testing devices to
test the insulation of cable which is connecting the inverter.
Even if the inverter is not in operation, DC terminals and
motor terminals could still have dangerous voltage.
Therefore, any work can not be started until it is electrically
discharged after the power supply has been switched off for 5
minutes.
The inverter’s grounding terminals must be connected to the
ground securely.
The grounding resistance of voltage class 200V is 100 or
less
The grounding resistance of voltage class 400V is 10 or
less
The grounding resistance of voltage class 660V is 50 or
less
Otherwise, there is a risk of causing electric shock and fire.
The input terminals (R, S, T) and output terminals (U, V, W) of
inverter must be connected correctly, otherwise it will cause
damage to devices inside the inverter.
It is forbidden to wire and/or operate the inverter when your
hands are wet; otherwise there is a risk of electric shock.
Please verify the rated voltage of inverter is consistent to the
voltage of AC power source.
Power supply cables and motor cables must be connected
securely and perpetually.
