Supply Voltage Connection - Lenze i950 Montage- Und Einschaltanleitung

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.
