DC Power Supply

The P24 DC power supply is for use with +24V input power applications. The wattage rating is the same
as the P01, 60W.

Rack Orientation and Mounting

Racks must be mounted as indicated in illustrations throughout this manual, so as to provide for vertical
airflow through the racks. That is, racks must never be mounted vertically, and must never be mounted
with the backplane horizontal (for example, flat on a horizontal panel or tabletop). Environmental
specifications apply only to the normal mounting configuration.
Rack dimensions, including overall dimensions and patterns for drilling holes for mounting, are given in
Figure 28 and Figure 29. Vertical spacing of racks, which is required for rack ventilation and for routing
wires, is shown in Figure 30.
