During installation the notes given in the documentation for the standard
device must be observed!
Danger!
Dangerous electrical voltage!
Dangerous electrical voltages may be applied to the connections of the brake
switch.
Possible consequences:
ƒ Death or severe injuries when touching the terminals.
Protective measures:
ƒ Disconnect the standard device and the brake switch from the mains before
carrying out any operations.
ƒ Check that all power terminals are deenergised.
Stop!
The motor brake control includes an electronic switch which can control a
motor holding brake.
The motor brake control module may only be connected to holding brakes
which correspond to the permissible data specified in the technical data.
If the permissible values specified in the technical data are not complied with:
ƒ The motor brake control module can be destroyed.
ƒ A safe operation of the motor holding brake cannot be guaranteed.
Further notes in the documentation of the standard device must be observed!
Stop!
Requirements on the brake cable (connection BD1/BD2):
ƒ If the brake cable is part of the motor cable, it must be shielded.
– An operation with unshielded brake cables can destroy the motor brake
control module.
– We recommend the use of Lenze system cables (motor cable with
separately shielded additional cores).
– Connect the shield to PE on both sides.
ƒ When using a permanent magnet holding brake, ensure the correct polarity
of the brake cable.
– If the terminals are reversed, the brake does not release. Since the motor
runs against the closed brake, the brake can be destroyed.
