3.1 Connection with Peripheral Units
WARNING
D
Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
D
Wiring should be performed only by qualified personnel.
Failure to observe this warning can result in an electric shock or a fire.
D
Make sure to ground the ground terminal
.
(
200V class: Ground to 100Ω or less, 400V class: Ground to 10Ω or less)
Failure to observe this warning can result in an electric shock or a fire.
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.)
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 can occur.
CAUTION
D
Verify that the rated voltage of the Converter coincides with the AC power supply voltage.
Failure to observe this caution can result in personal injury or a fire.
D
Do not perform a withstand voltage test of the Inverter and the Converter.
It may cause semi-conductor elements to be damaged.
D
Make sure to connect the Inverter and the Converter as shown in the connection diagram.
The Inverter or the Converter may be damaged.
D
Tighten terminal screws to the specified tightening torque.
Failure to observe this caution can result in a fire.
D
Do not connect the power supply to output terminals U/T1, V/T2, and W/T3.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
D
Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.
The Inverter can be damaged or internal parts burnt if these devices are connected.
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.
