4.4.1 Removal and Installation of the Device for Holding Down the
modules
The holding down the module is used to fix modules and guarantee safe transport/
contact. Shock and vibration especially affect long and heavy modules. For this
type of modules it is advisable to use the holding down the module device. The
market also offers very short, small and light modules. The holding down the mo-
dule device has not been designed for these modules as they are fixed enough by
the standard fastening.
The device for holding down the modules is attached to the housing with a screw.
It has three slits, through which the slide elements are inserted.
Proceed as follows:
1. Open the housing as described in Section 4.1.
2. Undo the fixing screw of the device for holding down the modules.
3. During assembly, ensure that the device for holding down the modules is
resting on the guide on the housing.
