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.
