Rack Mounting
Rack mount applications require the optional rack mount kits available
from National Instruments. Refer to Figure A-3,
, and the instructions supplied with the rack
mount kits to install your chassis in an instrument rack.
Note
You may want to remove the feet from the chassis when rack mounting. To do so,
remove the screws holding the feet in place.
Connecting Safety Ground
Caution
The PXI-1031/PXI-1031DC chassis is designed with a three-position inlet that
connects the cord set ground line to the chassis ground. To minimize shock hazard, make
sure the electrical power outlet you use to power the chassis has an appropriate earth safety
ground.
For DC powered applications, or if your power outlet does not have an
appropriate ground connection, you must connect the premise safety
ground to the chassis grounding screw located on the rear panel. Refer to
Figure 1-2,
Rear View of the PXI-1031 Chassis
, to locate the chassis grounding screw.
Complete the following steps to connect the safety ground.
1.
Connect a 10 AWG (2.6 mm) wire to the chassis grounding screw
using a grounding lug. The wire must have green insulation with a
yellow stripe or must be noninsulated (bare).
2.
Attach the opposite end of the wire to permanent earth ground using
toothed washers or a toothed lug.
Connecting to Power Source
Cautions
Do
not
install modules prior to performing the following power-on test.
To completely remove power, you
must
disconnect the AC power cable (and DC power,
if applicable).
If both AC and DC power cables are connected, the chassis will draw power from both
sources.
