Connecting Safety Ground
Caution
The PXI-1042 Series chassis are designed with a three-position NEMA 5-15 style
plug for the U.S. that connects the 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.
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-1042Q Chassis
, to locate the
chassis grounding screw. To connect the safety ground, complete the
following steps:
1.
Connect a 16 AWG (1.3 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.
