Motor holding brake connecon
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 isolaon
Sa
fe isolaon of the control card from the mains potenal is deacvated 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 br
ake are connected via safely isolated installed cables.
