The value that has been selected can be seen when the switch is set.
NOTE
An isolating device that is easy to access must be provided in the
power circuit.
!
WARNING
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 250 V (line supply)
F2: T800 mA H 250 V (line supply)
NOTE
Caution: Two-pole fuse
NOTE
The power supply PC board is suitable for the connection to IT
systems.
2.3.2 Voltage monitoring functions
The input voltage is monitored for undervoltage conditions.
Input voltage
(V
rated
= 1-ph. 230 V AC)
Response
Undervoltage: < 170 V 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.
Input voltage
(V
rated
= 1-ph. 115 V AC)
Response
Overvoltage < 95 V 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.
Undervoltages at the output Response
V (5 V) < 4.7 ... 4.85 V
(for t>100-200 µs)
Green OK-LED goes dark
The output voltages are shutdown
(CPU stop)
The system does not automatically restart (the
line supply voltage must be switched-out)
