The value that has been selected can be seen when the switch is set.
An isolating device that is easy to access must be provided in the
power circuit.
The protective conductor must be connected at the line supply
connector. It is not sufficient to connect the protective conductor at the
subrack itself.
There are following fuses on the printed circuit board of the power supplies:
F1: T800 mA H
F2: T800 mA H
Caution: Two-pole fuse
The power supply PC board is suitable for the connection to IT
systems.
The input voltage is monitored for undervoltage conditions.

Response
The output voltages are shutdown;
CPU stop (DSAVE signal)
After the power supply voltage has been
shutdown and the input voltage increases to
approx. 195 V, then the system automatically
restarts.
Response
The output voltages are shutdown;
CPU stop (DSAVE signal)
After the power supply voltage has been
shutdown and the input voltage increases to
approx. 100 V, then the system automatically
restarts.
