WARNING
Page
D
Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire may occur.
3 -2
D
Wiring should be performed only by qualified personnel.
Failure to observe this warning may result in an electric shock or a fire.
3 -2
D
Make sure to ground the ground terminal .
(
200V class: Ground to 100
Ω
or less, 400V class: Ground to 10
Ω
or less
)
Failure to observe this warning may result in an electric shock or a fire.
3 -2
D
Always check the operation of any emergency stop circuits after they are wired.
Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)
3 -2
D
Never touch the output terminals directly with your hands or allow the output lines to
come into contact with the Inverter case. Never short the output circuits.
Otherwise, electrical shock or grounding may occur.
3 -2
CAUTION
Page
D
Verify that the rated voltage of the Converter coincides with the AC power supply volt-
age.
Failure to observe this caution may result in personal injury or a fire.
3 -2
D
Do not perform a withstand voltage test of the Inverter and the Converter.
It may cause semi-conductor elements to be damaged.
3 -2
D
Make sure to connect the Inverter and the Converter as shown in the connection dia-
grams.
The Inverter or Converter may be damaged.
3 -2
D
Tighten terminal screws to the specified tightening torque.
Failure to observe this caution may result in a fire.
3 -2
D
Never connect the power supply to output terminals U/T1, V/T2, and W/T3.
The Inverter may be damaged.
3 -2
D
Do not connect phase-advancing capacitors or LC/RC noise filters to the output cir-
cuits.
The Inverter may be damaged or internal parts burnt if these devices are connected.
3 -2
D
Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent
protection circuit inside the Inverter to operate.
