Connecting Safety Ground
Warning The PXI-1000 chassis is designed with a three-position NEMA 15-5 style plug that
connects the ground line to the chassis ground. To minimize shock hazard, make
sure your electrical power outlet has an appropriate earth safety ground that is
connected whenever you power up the chassis.
If your power outlet does not have an appropriate ground connection, you
must connect the premise wire safety ground to the chassis grounding
screw located on the rear panel. Refer to Figure 1-2,
Rear View of the
PXI-1000 Mainframe , for a diagram of 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 toothed grounding lug. The wire must have green insulation
with a yellow stripe or must be non-insulated (bare).
2. Attach the opposite end of the wire to permanent earth ground using
toothed washers or a toothed lug.
Connecting to AC Mains Power and Testing Power up
Caution Make sure the main power switch located on the rear panel of the PXI-1000 is in
the Off position (0). Refer to Figure 1-2,
Rear View of the PXI-1000 Mainframe , for
a diagram of the main power switch.
Do not install modules prior to performing the first power-on test.
The power supply is universal, which means the mainframe can connect to
all standard worldwide input voltages. Refer to Chapter 1,
Getting Started ,
for power cord specifications. Attach input power through the rear AC inlet
using the appropriate line cord supplied. Refer to Figure 1-2,
Rear View of
the PXI-1000 Mainframe , for a diagram of the IEC 320 inlet.
Push the main power switch to the On (1) position. Then push the remote
power switch to the On position (if not already on). Observe that all fans
become operational. Note that the main power switch (rear panel) enables
the power module to receive AC power. The remote front panel standby
switch allows the power module to provide power to the PXI backplane
(if the rear main power switch is on). For this reason, you can leave the
main power switch on and use the remote On/Off (Standby) switch on the
front to power up and power down the backplane.
