Installation and Configuration
Connecting Safety Ground
Caution
The NI PXIe-1085 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 NI PXIe-1085 Series 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.
Connecting to Power Source
Cautions
Do
not
install modules prior to performing the following power-on test.
To completely remove power, you
must
disconnect the AC power cable.
Attach input power through the rear AC inlet using the appropriate AC power cable supplied.
Refer to Figure 1-2,
Rear View of the NI PXIe-1085 Series Chassis
, to locate the AC inlet.
The Inhibit Mode switch allows you to power on the chassis or place it in standby mode. Set the
Inhibit Mode switch on the back of the chassis to the
Manual
position. Observe that all fans
become operational and all three front panel LEDs are a steady green. Switching the Inhibit
Mode switch to the
Default
position allows the system controller to control the power supply.
