Supply voltage connection

Supply voltage connection
An external 24 V supply voltage to X5:24E/GE is necessary for supplying the control electronics.
If the control electronics are supplied independently of the AC grid of the inverter, the inverter can also be
configured when the AC grid is turned off. Communication via existing networks also remains available.
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.
