Motor Holding Brake Connection - Lenze i950 Montage- Und Einschaltanleitung

Motor holding brake connection

The inverter is designed for 24 V brakes. A motor holding brake is connected to X106 and supplied via X107.
DANGER!
Loss of the safe isolation
Safe isolation of the control card from the mains potential is deactivated when the motor and motor holding
brake are connected via a system cable AND X5 and X107 are supplied by a common power supply unit. This
also applies when using a SELV/PELV power supply unit.
Possible consequences: Electric shock in the event of a fault.
▶ Supply X107 and X5 by separate SELV/PELV power supply units if the motor and motor holding brake are
connected via a system cable.
X107 and X5 can be supplied by a common SELV/PELV power supply unit if the motor and motor
holding brake are connected via safely isolated installed cables.
