Справочник Пользователя для National Instruments NI PXI-1056

Rack-mount applications may require the optional rear rack mount kit 
available from National Instruments. Refer to Figure A-3, 

, and the instructions supplied with the rack mount kits 

to install your PXI-1056 in an instrument rack.

You may want to remove the feet from the PXI-1056 when rack mounting. To do so, 

remove the screws holding the feet in place. 

The PXI-1056 chassis is 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, 

, 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.
