circuit breaker in the supply circuit.
The connector
X1
is not permissible as a circuit breaker.
The connector
X1
is permissible only for the internal wiring and may be
plugged only in the voltageless state or be split.
The connector
X1
must not be used for a power cable removable of the
terminal user.
The protective conductor must be connected at connector X1, pin 4. It
is not sufficient to connect a protective conductor.
The following fuses are located on the power supply PC board
F 1:
T800 mA H 250 V (supply)
F 2:
T800 mA H 250 V (supply)
F:
T50 mA H
NOTE
Caution: bipolar fuse
An external fuse must be dimensioned according to the following operating
data: Input current (at 230 V):
In = 600 mA
Fuse link:
I²t = 0.5 A²s
Peak inrush current:
Is = 25 A
NOTE
The power supply PC board is suitable for the connection to IT
systems.
2.1.2 Voltage monitoring functions
The input voltage is monitored for undervoltage and overvoltage conditions.
Input voltage
(V
rated
= 1-ph. 230 V AC)
Response
Undervoltage:
< 170 ...175 V
Green OK LED goes dark
The output voltages are shutdown;
CPU stop (DSAVE signal)
The system automatically restarts when
the input voltage increases to approx.
190 V.
Overvoltage
> approx. 265 V
Red fault LED is lit;
The output voltages are shutdown,
CPU stop (DSAVE signal)
No automatic restart (the line supply
voltage must be disconnected)
