• Modification—Do not modify any part of the chassis from its original
condition. Unsuitable modifications may result in safety hazards.
Chassis Cooling Considerations
The PXI-1052 is designed to operate on a bench or in an instrument rack.
Determine how you want to use the PXI-1052 and follow the appropriate
installation instructions.
Providing Adequate Clearance
Openings in the top and along both sides of the chassis facilitate power
supply and module cooling. Air enters through filters and fan inlets in the
lower rear of the chassis and exits through the upper sections on both sides
and through the top, as shown in Figure 2-1. Provide adequate ventilation
space around the PXI-1052 on a bench top or in an instrument rack so that
the fans (air inlets) and the air outlet apertures along both sides and the top
of the chassis are not obstructed. Keep other equipment a minimum of
76.2 mm (3 in.) away from the air inlets on the rear of the chassis.

When rack mounting the PXI-1052, provide at least 44.5 mm (1.75 in.)
clearance above and on the sides of the unit for adequate venting.
High-power applications can require additional clearance.
