National Instruments PXI NI PXI-1052 用户手册

The PXI-1052 chassis is designed with a three-position NEMA 5-15 style plug 

for the United States 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 the 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, 

, to locate the chassis grounding screw. Complete the following 

steps to connect the safety ground.

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.

Do not install modules prior to performing the following power-on test.

Attach input power through the rear AC inlet using the appropriate 
AC power cable supplied. Refer to Figure 1-2, 

, to locate the AC inlet.

To completely remove power, you must disconnect the AC power cable.

The power switch allows you to power on the chassis or place it in standby 
mode. Push the power switch to the On (recessed) position (if not already 
on). Observe that all fans become operational and the system power switch 
LED is a steady green. 

The system power indicator LED should be lit indicating that system power 
is available to both the PXI and SCXI subsystems. The PXI subsystem 
remains powered as long as the system power is on. However, you can 
control the SCXI subsystem using the power switch on the rear panel.
