Connecting the Safety Ground
Caution
The PXIe-1090 chassis is designed with a three-position IEC 60320 C14
inlet for the U.S. that connects the ground line to the chassis ground. For proper
grounding, you must use a suitable cordset to connect this inlet to 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. To connect the
safety ground, complete the following steps:
1.
Connect a 16 AWG (1.3 mm) wire to the chassis grounding screw (M4 SEMS) 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 a Power Source
Caution
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.
The Power Inhibit switch allows you to power on the chassis or place it in standby mode. With
an empty chassis in Default Mode, press down the Power Inhibit switch and hold it down for
one second. Observe that all fans become operational, the System LED is green, and the MXI
LED is solid amber (without a host PC). Pressing and holding the Power Inhibit switch again
for one second will return the chassis to standby.
