Connecting
braking resistors
•
Use two tightly twisted leads or a 2-core shielded power cable. Cross section ac-
cording to the rated output current of the inverter.
•
Protect the braking resistor with a bimetallic relay / thermal overload relay (
→
Wir-
ing diagram for basic unit, power section and brake). Set the trip current according
to the technical data of the braking resistor. SEW-EURODRIVE recommends us-
ing an overcurrent relay of trip class 10 or 10A in accordance with EN 60947-4-1.
•
For braking resistors of the BW...-T / BW...-P series, the integrated temperature
switch/overcurrent relay can be connected using a 2-core shielded cable as an
alternative to a bimetallic relay.
•
Install the flat-type braking resistors together with the appropriate touch guard.
