4.2 Installation of the IRMA gateway
6 holes with a diameter of 4.8 mm each are provided on the IRMA gateway housing for
mounting to the vehicle. At least 4 of these holes must be used for screwing down the
housing.
When installing the IRMA gateway, see to it that sufficient space is available for connecting
the connectors (space required approx.: 200 mm x 226 mm).
When installing the IRMA gateway, a low-resistance connection must be established
between the IRMA gateway housing and the vehicle chassis. This can be achieved by
screwing the IRMA gateway directly to the vehicle chassis (electrically conductive material).
Use a tooth-lock washer for mounting.
If the low-resistance connection cannot be realized in this way for reasons of standards or
because the chassis is non-metallic (e.g. glass-fiber reinforced plastics), an additional
grounding cable must be fitted (yellow/green, conductor cross-section >4 mm²,
recommended length: ≤ 25 cm), see Section 5.3.3, p. 31.
4.3 Numbers of IRMA MATRIX sensors per door
The following diagram (Fig. 15) serves to determine the number of sensors for each door,
depending on the height and/or width of the door.
1 IRMA MATRIX sensor must be used if the intersection point of door height and door
width comes to sit to the left of the blue line.
2 IRMA MATRIX sensor must be used if the intersection point of door height and door
width lies between the blue and red lines.
The values indicated are recommendations - in case of deviations please contact iris-
GmbH.
