PXI-1011 Chassis Installation
Caution Equipment described in this document must be used in an installation
category II environment in accordance with IEC 60664. This category requires
local-level supply MAINS-connected installation.
Connecting Safety Ground
The PXI-1011 chassis is designed with a three-wire style cord that connects the
ground (protective earth) line to the chassis ground. To minimize shock hazard, the
electrical power outlet must have an appropriate earth safety ground that is connected
whenever you use the chassis.
Caution
If the power outlet does not have an appropriate ground connection or the power frequency
is above 63 Hz, you must connect the premise safety ground to the chassis grounding screw
located on the rear panel. Refer to Figure 2-1 to connect the safety ground, while
completing the following steps:
1.
Connect a 16 AWG (1.3 mm diameter) or larger wire to the chassis grounding screw
using the supplied 10-32 screw and a toothed lug. The copper wire must have green
insulation with a yellow stripe or must be non-insulated (bare).
2.
Attach the other end of the wire to permanent earth ground using toothed washers or
a toothed lug.
The electrical wiring codes in your area may not consider soldered connections
as reliable. A crimp style connector is recommended with two crimps applied to improve
reliability.
