1 - Fastening screw for functional earth
2 - Fastening screw for supply voltage: -
3 - Fastening screw for supply voltage: +
4 - Connection for functional earth
5 - Connection for supply voltage: -
6 - Connection for supply voltage: +
Note:
Relevant for North America:
The tightening torque of the terminal block screws is 3 lb in. (0.34 Nm).
Note:
Make sure the following requirements are met:
Supply line length < 3 m
Supply line cross section is suitable for 5 A
Pull the terminal block(s) off the switch and connect the voltage supply
lines as follows:
First connect the protective conductor to the protective conductor
terminal.
Connect the PoE voltage to the 3-pin terminal block.

Operating the device
By connecting the voltage supply via the voltage supply socket(s), you start
the operation of the device.
2.1.8
Connecting data cables
Note the following general recommendations for data cable connections in
environments with high electrical interference levels:
Keep the length of the data cables as short as possible.
Use optical data cables for the data transmission between the buildings.
When using copper cables, provide a sufficient separation between the
power supply cables and the data cables. Ideally, install the cables in
separate cable channels.
Verify that power supply cables and data cables do not run parallel over
longer distances. To reduce inductive coupling, verify that the power
supply cables and data cables cross at a 90° angle.
