Equipotential bonding
The device must be connected to the equipotential bonding according to EN 60728-11. Use the equipotential bonding
connection at the device.
To connect the outer conductor of the coaxial cable to the equipotential bonding, use e.g. QEW earthing angles or CFA earth
connection blocks at the inputs and output.
2.3.
Power supply
The devices are equipped with two redundant power supplies to connect them e.g. to different power sources (e.g. a normal mains
socket and a UPS). The LEDs show the status of the power supply.
If a power supply fails, the unit will start with an alarm tone. You can deactivate the alarm by pressing the red button.
Alternatively, you can remove the unused power supply from the device.
Connect both power supplies with the enclosed cables to 230 VAC.
Devices with power supply 36…60 VDC (MIE xx-xx/48)
The power supply input connectors are 2 × M4 screws.
Connect the DC connectors to 36…60 VDC.
Important:
Ensure that the polarity is correct. Use sufficient conductor cross sections.
