IRMA MATRIX R2 CAN Installation
manual
released
Rev. 1.6
Use cable clips to secure all cables every 30 cm. The cables must not be fixed to parts which
can normally be shifted or replaced during maintenance.
When fixing the cables in their positions the
minimum distance
to power lines/conductor
rails of 20 cm and to battery or binary control lines of 10 cm must be observed.
The cables must be laid with sufficient reserve length so that they can be re-fitted to
connectors at least three times.
When laying the cables the
minimum bending radii
given in the "Components for IRIS
sensors on the CAN BUS" must be observed.
The shield of the cabling must be connected to the potential of the vehicle chassis as often
as possible via a low-resistance connection - i.e. at each sCON connector. This is done either
by directly mounting it to the chassis or by the additional installation of chassis grounding
cables.
Yellow-green cables with a line cross section of 4 mm² must be used as grounding cables
(see section 5.3, p. 29 et sequ.).
At all clamps and disconnectable plug connectors the individual cables must be identified
in a practical manner. The individual cables are to be marked with a label attached to the
cable at approx. 10 cm from the connector.
Requirements to auxiliary material such as cable clips, marking clips, shrinkdown tubing:
Only such auxiliary material must be used which is resistant to the conditions to which the
cables are exposed, e.g. resistance to diesel fuel. Its fire behavior must comply with the
requirements of EN 45545.
For the operating characteristics, cable lengths, technical data and item numbers please
refer to our catalog "IRMA MATRIX components for Ethernet installations".

EMC-compatible installation/grounding in accordance
with EN 50153
In order to achieve EMC-compatible installation in motorized vehicles (E1, e1 permit) and
railways (EN 50121-3-2) and to observe EN 50153 (Railway applications - Protective
provisions relating to electrical hazards), it must be ensured that the connection between
the housing of the sensor and IRMA gateway and the chassis potential is conductive. For
this purpose an additional connection is installed between the device housing and the
chassis. This is realized either by screwing the housing down directly on bare and uncoated
metal surfaces or by the installation of an additional grounding cable.
The grounding cable (yellow/green, line cross section 4 mm²) should be as short as
possible. We recommend not exceeding a length of 25 cm, if possible. It is installed
between the sCON or gateway housing and a suitable point on the chassis (see section
5.3.1, 5.3.2.).
