Magnum XS 450 Power System –48 VDC User’s Manual Page 7
Mounting
The unit is self-supporting, but designed to be bolted to the floor of the housing structure.
Figure 3.2-2 shows the footprint of the box frame and the mounting points with dimensions.
Systems with multiple box frames are bolted together with each frame touching, side by side.
The side panels where two frames touch are removed so that cables can pass between the
frames. A kit with the necessary hardware to bolt two cabinets together (0M-3441) is
available from APC.

Ventilation
The rectifier modules for this system have fans that provide front-to-rear airflow for internal
cooling. The Magnum XS 450 Power System frame should be mounted such that there is
free airflow to the front and rear of the unit. [Refer to
Section 7.3
for environmental
characteristics.] Free airflow should be ensured so that the power system can provide full
power at ambient temperature without de-rating.
