5.4 Earthing System

The following items have to be observed to guarantee a safe dissipation of elec-
tronic interference:

– Appliance and switch board have to be connected to the nearest possible cen-

tral earthing point.

– Make sure of a possibly low inductive connection between appliance and

switch board.

– All data cables connected to the appliance have to be of the shield type.

– The screens have to be earthed on both sides. A low ohm connection between

the connected systems is essential. Avoid high equalizing currents through the
cable screen due to voltage fluctuations.

– The earthing connection is to be carried out with min. 4 mm² cross section.

5.5 Buzzer In/Out

There is a buzzer integrated in the front behind the front foil. The buzzer can be
activated with a Beijer Electronics RBC software command or with a buzzer-in
signal. Buzzer-out is a relay contact parallel to the integrated buzzer that can be
used to switch an external signal device.

The buzzer-in and -out can be connected to the 4-pole Phoenix connector:

Please see the RBC software manual MAEN986 for further information.
