Wiring rules

The input power must be connected to L1/L2/L3, and it is strictly prohibited to connect to U/V/W

Motor wire ≤ 50m, extra long requires an output filter OFL

Separate the wiring of the main circuit and control line, and ground the shielded wire

Power supply ≥ 500kVA must be connected to DC reactor DCR

The braking resistor should only be connected to P (+) – DB, and it is strictly prohibited to connect to P-N
