Orientation
The 912x range of power supplies can be mounted on type T35 [top hat] DIN-rail, or surface
mounted. In either case, the orientation must allow air to be naturally convected through the unit
to achieve the maximum cooling effect. To make use of the full temperature range specified for
a unit it must be mounted on a vertical surface with the switches at the top - as shown in the
right-hand part of Figure 1.
