Always switch off the brake on the DC and AC sides with
– all hoist applications,
– drives which require a rapid brake response time, and
– CFC and SERVO operating modes.
Brake rectifier in
the control cabinet
Route the connection cables between the brake rectifier and the brake separately from
other power cables when installing the brake rectifier in the control cabinet. Joint routing
is only permitted when the power cables are shielded.

* With sizes 1 and 2, there is no PE connection next to the mains and motor connection terminals (X1, X2). In this
case, use the PE terminal next to the DC link connection (X4).
Caution: Observe the operating instructions of the respective motors when connecting the brake!
STOP!
If the brake rectifier is connected via the supply supply lead, the function of the brake
will be restricted.
• Connect the brake rectifier using a separate supply system lead.
•
Powering it from the motor voltage is not permitted!
