• To remove the mGuard industrial rs from the DIN rail, insert a screwdriver horizontally
in the locking slide under the housing, pull it down – without tilting the screwdriver – and
then pull up the mGuard industrial rs.
12.3.2 Connecting the supply voltage
WARNING: The mGuard industrial rs is designed for operation with a DC voltage of
9 V DC ... 36 V DC/SELV, 0.5 A, maximum.
Therefore, only SELV circuits with voltage limitations according to EN 60950-1 may be
connected to the supply connections and the signal contact.
The supply voltage is connected via a terminal block with screw locking, which is located on
the top of the device.

– NEC Class 2 power source 12 V DC or 24 V DC
– -25% ... +33% Safety Extra Low Voltage (SELV/PELV, redundant inputs isolated)
– 5 A, maximum
– Buffer time 10 ms, minimum at 24 V DC
Redundant power supply
A redundant supply voltage can be connected. Both inputs are isolated. The load is not dis-
tributed. With a redundant supply, the power supply unit with the higher output voltage sup-
plies the mGuard industrial rs alone. The supply voltage is electrically isolated from the
housing.
If the supply voltage is not redundant, the mGuard industrial rs indicates the failure of the
supply voltage via the signal contact. This message can be prevented by feeding the supply
voltage via both inputs.
12.3.3 Connecting to the network
WARNING: Only connect the mGuard network ports to LAN installations.
When connecting to the network, use cables with bend protection on the plugs.
Cover unused sockets with the dust protection caps provided.
Some telecommunications connections also use RJ45 sockets; these must not be con-
nected to the RJ45 sockets of the mGuard.
LAN port
• Connect the local computer or the local network to the LAN port of the mGuard using a
UTP Ethernet cable (CAT5).
