Wiring diagram
X2
Screw terminal with screw lock (3*1.5 mm
wires dressed with wire end ferrules with insulating
collars)
Make sure that the strain relief is properly mounted.
X1
Cage clamp terminal (0.5 mm
wires dressed with wire end ferrules with insulating
collars)
Make sure that the strain relief is properly mounted.
The PE/ground conductor must be connected to the power supply. A PE/ground terminal
on the rack is inappropriate. The PE/ground conductor must be green with yellow stripe
(green/yellow).
Ungrounded installation of the rack is not planned.

Voltage monitoring
Input voltage
The input voltage is monitored for low level.
Input voltage
Undervoltage < approx. 85 V
Voltage dips ≤ 20 ms are buffered.
The power supply unit and therefore the system are restarted automatically on recovery from
a voltage dip below the permissible mains voltage.
The power on/off sequence (e.g. generation of a RESET or SYSFAIL signal) corresponds to
the reaction to manual operation of the mains switch.
