Danger
Caution
1 Before wiring, please confirm the cut-off of input power supply.
Risk of electric shock and fire.
2 Wiring operations must be carried out by electric engineerting specialists.
Risk of electric shock and fire.
3 Ground terminal must be reliably grounded.
(
380V class
:
especially the third
ground
)
Risk of electric shock and fire.
4 After connecting with the terminal of emergency stop, be sure to check the
validity of actions.Risk of injury.
(
The responsibility of wrong wiring is
undertaked by users.
)
5 Do not directly touch the output terminals. Do not connect the output terminals of
inverter with the housings. Do not be short circuit between output terminals.
Risk of electric shock and short-circuit.
1
Make sure rated voltages of AC main circuit power supply and inverter are the
same. Risk of injury and electric shock.
2 Do not test withstand voltage of inverter.
It will damage semiconductor components.
3 Please connect braking unit or braking resistor according to wiring diagram.
Risk of fire.
4 Please use the specified torque screwdriver fastening terminals. Risk of fire.
5 Do not connect the cable of input power supply to output U
、
V
、
W terminals.
It will damage the internal of the inverter if adding voltage onoutput terminals.
6 Do not switch phase-shift capacitor into output circuit. It will damage the internal
of the inverter.
7 Do not switch electric-magnetic switch and electric-magnetic contactor into ouput
circuit. When the inverter is in operation with a load, surge current generated by
electromagnetic switches, electromagnetic contactors will cause the over-current
protection circuit action of inverter.
