After mounting

Observe the notes on Grounding [} page 14].

Mounting of the SMA antennas Important:

For proper device operation, all three SMA antennas X1, X2 and X3 must be mounted.

2.2 Grounding

Functional earth

The L-coded M12 connectors of the device's power supply have a pin FE (functional earth), which is

connected to the metal housing of the device. The metal housing in turn has a central grounding point for

the functional earth. You can ground the device as follows:

- Ground the device via the metal housing and/or,

- Ground via FE of the power supply connection and/or,

- Grounding can be done separately via a cable lug and the mounting hole if the device is mounted on

a non-conductive base.

Ensure that the contacts are perfect and that the cable cross-section is sufficient.

2.3 Demounting

Required tools for demounting

For demounting, you need an Allen key to loosen the M4 hexagon socket head screws according to DIN

912 or ISO 4762.

Before demounting

Prepare for demounting:

- Disconnect the part of the plant to which you have mounted the device from the power supply.

- If the device is dirty, clean it first. It is particularly important to clean dirty screw connections.

- Before demounting, loosen all screw connections at the terminals and disconnect the cables.

Demounting

To disassemble the device, e.g. when replacing the device, proceed as follows:

- Make sure that the part of the plant on which you have mounted the device is de-energized.
