Functional earth (FE)

All existing connections for the functional earth must be connected to earth:

Functional earth via the fastening holes

The fastening holes also serve as connections for the functional earth (FE).

Make sure that the box is earthed with low impedance via both fastening screws.

The pins of the supply connectors marked with "FE" are directly connected to the functional earth potential of the fastening holes.

Connect the functional earth of the "FE" cores in accordance with the following instructions:

If the remote station is a device with 7/8"-connector: connect the devices with a pre-configured cable. Possible types of preconfigured cables:

Otherwise: ground the "FE" core with low impedance as near as possible to the remote station.
