A: Common power supply to motor and brake
i
Not suitable for inverter operation.
B: Separate power supply to brake
For inverter operation, connect the motor with Y
or ∆ connection according to the inverter settings.
Switch-off in the DC circuit
• Remove jumper between terminals 3 and 4.
• Connect a contactor between terminals 3 and 4.
Switch-off in the AC circuit
• Jumper between terminals 3 and 4.
• Contactor contacts in the supply lines behind
terminals 5 and 6.
Motor current switch-off
Jumper between terminals 3 and 4
→ not possible for separate power supply to the
brake.
