Mechanical installation of resistors
All brake resistors must be installed outside the drive. Obey the resistor manufacturer’s
instructions.
Electrical installation

Connection diagram
See section
Power cable connection diagram (page 87)

Connection procedure
•
Connect the resistor cables to the R+ and R- terminals in the same way as the
other power cables. If a shielded three-conductor cable is used, cut the third
conductor and ground the twisted shield of the cable (protective earth conductor
of the resistor assembly) at both ends.
•
Wire the thermal switch to a digital input on the drive control unit as shown below.

Start-up
Note: New brake resistors may be coated with storage grease. As the brake chopper
operates for the first time, the grease burns off and may produce some smoke. Make
sure there is sufficient ventilation.

Parameter settings
Set the following parameters:
•
Disable the overvoltage control of the drive with parameter 30.30 Overvoltage
control.
