Connecting the brake rectifier
Use contactors of utilization category AC-3 for K11 and K12 only.
Always disconnect the brake in the DC and AC circuits in:
• All hoist applications.
• Drives which require a rapid brake response time.
If the brake rectifier is installed in the control cabinet, route the connecting leads
between the brake rectifier and the brake separately from other power cables. Routing
together with other cables is only permitted if the other cables are shielded.
Note the corresponding connection regulations for brakes without BG/BGE or BME.
Refer to the SEW publication "Drive Engineering – Practical Implementation, volume 4"
for detailed information about this topic.
The connection of the brake rectifier requires a separate supply system cable;
supply from the motor voltage is not permitted!
