Chapter 2 Installing and Configuring the PXI-1011 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.
