2.3.4 Connecting the supply voltage
The supply voltage is connected via a plug-in screw terminal block, which is located on the
top of the device.
Figure 2-4 Connecting the supply voltage
The mGuard rs4000 Switch has a redundant supply voltage. If you only connect one supply
voltage, you will get an error message.
• Remove the plug-in screw terminal blocks for the power supply and the service con-
tacts.
• Wire the supply voltage lines with the corresponding screw terminal block (P1/P2) of
the mGuard. Tighten the screws on the screw terminal blocks with 0.5 ... 0.8 Nm.
• Insert the plug-in screw terminal blocks into the intended sockets on the top of the de-
vice.
The P1 status LED lights up green when the supply voltage has been connected properly.
On the mGuard rs4000 Switch, the P2 LED also lights up if there is a redundant supply volt-
age connection.
The device boots the firmware. The Stat LED flashes green. The device is ready for opera-
tion as soon as the Ethernet socket LEDs light up. Additionally, the P1/P2 LEDs light up
green and Stat LED flashes green at heartbeat.
Redundant power supply (mGuard rs4000 Switch)
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 rs4000 Switch alone. The supply voltage is electrically isolated from the
housing.
If the supply voltage is not redundant, the mGuard rs4000 Switch indicates the failure of one
supply voltage via the signal contact. This message can be prevented by feeding the supply
voltage via both inputs or by installing an appropriate wire bridge between the connections.
WARNING: The device is designed for operation with a DC voltage of
11 V DC ... 36 V DC/SELV.
Therefore, only SELV circuits with voltage limitations according to
IEC 60950/EN 60950/VDE 0805 may be connected to the supply connections and the
signal contact.
