Connecting the power supply
DANGER
IN SAFETY-RELEVANT APPLICATIONS, THE POWER SUPPLY
USED TO POWER THE XN300 SYSTEM MUST BE A PELV POWER
SUPPLY UNIT.
The two 24 V V+ terminals are internally connected to
each other (X6:
a
and
b
), as are the two 0 V GND terminals
(X6:
c
and
d
). Only one V+ and one 0 V terminal need to
be connected in order to power the gateway. The internally
connected terminals can be used to extend the 24 V and
0 V supply voltage connections. However, it is necessary
to make sure that a total current of 4 A is not exceeded
per terminal.
External 24 Vdc voltages can also be distributed
using an XN-322-4PS-20 power distribution module or
XN-322-18PD-P and XN-322-18PD-M field potential
distributor modules.
The plug connector with push-in spring-cage terminal
FMC 1.5/4-ST-3.5 is included in the scope of supply.

The device must be powered with a galvanically isolated
power supply with a rated voltage of 24 Vdc. A ULT 249
fuse (maximum 4 A) must be installed between the power
supply and the device.
