7.3 Mounting the control unit

• The BODAS controller must be mounted in the vehicle so that it does not bounce
against other vehicle parts and additional mounting elements of the control unit.
• This tightening torque applies for fitting without washer. The equivalent tightening
torque must be calculated when using washers. For recommended screw sizes and
tightening torques, refer to the following table.

• Rexroth's consent is required if mounting is different from above.
• The minimum distance between the underside and the mounting surface of the
vehicle is 1 mm.
• For the RC4-5-30 control unit, the following applies: The distance between the
underside and the mounting surface should be less than 10 mm. If the control
unit is not mounted with a holder, it should be mounted with four distance bolts
guaranteeing this distance and preventing bending of the base plate in the area of
the screw holes.
• The evenness of the mounting surface between points a, b, c and d
(drawing see data sheets 95204, 95205, 95206, 95207 and 95208) is 0.5.
• The wiring harness should be fixated in the area in which the control unit is
installed (spacing < 150 mm) in such a way that the in-phase excitation with the
control unit occurs (e.g. at the control unit tightening point).
• The wiring harness should be mounted in such a way that there is enough space for
the mating connector to be unplugged without having too much force acting on the
mating connector.
• If the mounting surface is not sufficiently even, place flexible compensating
elements between the mounting points of the BODAS controller and the mounting
surface.
