4.2 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.
Ballast device 6EP1566-3AA00 must be mounted so that it is to the right of the PSU400M
24 V/20 A power supply.
When mounting the PSU400M together with the ballast device, the same derating curves
apply.
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.
