Intentional damage
The product must be fastened to a flat mounting surface, so that there is no strain on the
housing when the module is screwed down. The mounting distances will depend on which
plug-in connectors are used and on the bending radius of the cables.
To install the system, proceed as follows:
}
Fit 2 x M4 internal threads on the mounting surface.
}
Use fixing screws with washers. In environments with vibration we recommend that you
use locking washers.
}
When using internal hexagonal fixing screws with a strength class of 8.8, tighten the
mounting screws with a torque of 2.6 Nm to 3.3 Nm.
}
Use two fixing screws to attach the product to the mounting plate.
}
Attach the functional earth.
The functional earth can be connected to pin 5 of the X31 connector or to the lower fix-
ing screw (X0).
We recommend that you connect the functional earth to the lower fixing screw (X0).
Minimum conductor cross section of the earth cable on the fixing screw (X0) is 2.5 mm².
For the fixing screw you can use the supplied ratchet screw for the functional earth con-
nection.
Tighten the fixing screw with a torque of 1.2 Nm.
