Fig 4.7 Main circuit wiring diagram for AC 3PH 380V(-15%)–440V(+10%)
Note:
1. The fuse, DC reactor, brake unit, brake resistor, input reactor, input filter, output reactor and
output filter are optional parts. See Peripheral optional parts for details.
2. P1 and (+) have been short connected by default for 380V 132kW and above inverters. If users
need to connect to external DC reactor, take off the short-contact tag of P1 and (+).
3. When connecting the brake resistor, take off the yellow warning sign marked with PB, (+) and (-)
on the terminal block before connecting the brake resistor wire, otherwise, poor contact may
occur.
4. Built-in brake unit is optional for 380V 45kW-110kW models.
