5. Installation
General:
• The site chosen for the installation of the system must ensure that no excessive
electromagnetic loads are present.
• The power supply connection must be equipped with a line filter of type FN 660 (Schaff-
ner) or equivalent.
• For the external 24-volt supply, a line filter of type FN 2060 (Schaffner) or equivalent
must be provided.
• Care must be taken to ensure that the line filters are in good contact (low resistance) with
the mounting plate of the service cabinet.
• A clean grounding point must be provided for the equipotential bonding.
• Power supply cables are to be kept away from remote measurement/data lines (> 30 cm).
• All cables, unless otherwise specified, must be screened (> 80% coverage); they are to
be connected to the rack.
• The rack is to be equipped with separate equipotential bonding.
• The connection of the cable screen should be as short as possible.
• Cables for data transmission (CAN, RS232, etc.) must be screened. There must not be
any potential difference between the interface of the cable screen and ground. The cable
screen must have good contact with the housings of the plug connectors.
• The cables for remote racks must be laid protected against mechanical damages (CAN,
RS 232 etc.).

Connection of the Sensors:
1. By means of the MAT module, directly to the rack:
The remote measuring cables for passive/active sensors must be screened (> 80 %
coverage), and the cable screen is to be connected to the terminals provided.
2. By means of the MAT-TS module in the service cabinet (40-way ribbon cable):
The maximum length for 40-way ribbon cables is 5 meters.
MUT-module connected to MAT-TS-module
Passive/active sensor cables and analogue output cables are usually screened. The cable
screen is to be connected directly, over the shortest possible distance, to the screening terminal
provided.
