5. Regenerative breaking unit connection terminals
The Inverters rated more than 18.5kw don’t contain a BRD circuit. If regenerative braking is required
an external BRD circuit (Option) is required along with the resistor (Option).
Connect external regenerative braking unit terminals (P, N) to terminals (P,N) on the inverter. The braking resistor is
then wired into the External Braking unit and not directly to the Inverter.
The cable length should be less than 5 metres, and twist the two connecting wires to reduce
inductance.
6. Earth (G )
Make sure that you securely ground the Inverter and motor for prevention of electric shock.
The inverter and motor must be connected to an appropriate safety earth and follow the local
standard. Failure
to do so constitutes an electrical shock hazard.
