Other mounting positions

For mounting positions that deviate from the standard mounting position, derating factors
(reduction of the output power or the permissible ambient temperature) must be observed in
accordance with the following diagrams.
Note
In the case of mounting positions that deviate from the standard mounting position, reduced
mechanical resistance of the devices against vibration and shock must be expected.
Particularly when installing on a vertically fastened standard mounting rail, additional
measures may be required, e.g. to prevent the device from slipping on the standard
mounting rail.
