Refer to the table in Section 10.1 for wire sizes.

The length of the main circuit wire in Section 10.1 should be no longer than 30m. If the wire is longer than 30m, the wire size (diameter) must be increased.

Tighten the screws on the terminal board to specified torque.

2.2Standard connections

Warning

 

• Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3). ￿

 

Connecting input power to the output could destroy the inverter or cause a fire.

 

• Do not connect a regenerative braking resistor to any DC terminal (between PA/+ and PC/-, or

 

between PO and PC/-).

 

If a braking resistor is connected by mistake, it may overheat extremely and cause a fire.

Prohibited

Connect resistors as directed in the instructions for Section 5.19.

• Within 15 minutes after turning off input power, do not touch wires of devices (MCCB) connected to

 

 

the input side of the inverter. ￿

 

That could result in electric shock.

 

• Ground must be connected securely. ￿

 

If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or

 

current leak occurs.
