J Wiring
WARNING
Page
D Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
3 - 2
D Wiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur.
3 - 2
D Be sure to ground the ground terminal.
(400-V and 575-V Class Inverters: Ground to 10 Ω or less)
Otherwise, an electric shock or fire can occur.
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 Panel casing. Never short the output circuits.
Otherwise, electrical shock or grounding can occur.
3 - 2
CAUTION
Page
D Check to be sure that the voltage of the main AC power supply satisfies the rated volt-
age of the Inverter Panel.
Injury or fire can occur if the voltage is not correct.
3 - 2
D Do not perform voltage withstand tests on the Inverter Panel.
Voltage withstand test can damage semiconductor elements and other components.
3 - 2
D Connect Braking Resistor Units and Braking Units as shown in the I/O wiring exam-
ples.
Otherwise, a fire can occur.
3 - 2
D Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.
3 - 2
D Do not connect AC power to output terminals U, V, and W.
The internal Inverter Module will be damaged if voltage is applied to the output terminals.
