Chapter 2 Installation and Configuration©National Instruments Corporation2-3PXI-1000 User ManualConnecting Safety GroundWarning The PXI-1000 chassis is designed with a three-position NEMA 15-5 style plug thatconnects the ground line to the chassis ground. To minimize shock hazard, makesure your electrical power outlet has an appropriate earth safety ground that isconnected whenever you power up the chassis.If your power outlet does not have an appropriate ground connection, youmust connect the premise wire safety ground to the chassis groundingscrew located on the rear panel. Refer to Figure 1-2, Rear View of thePXI-1000 Mainframe, for a diagram of the chassis grounding screw. Toconnect the safety ground, complete the following steps:1. Connect a 16 AWG (1.3 mm) wire to the chassis grounding screwusing a toothed grounding lug. The wire must have green insulationwith a yellow stripe or must be non-insulated (bare).2. Attach the opposite end of the wire to permanent earth ground usingtoothed washers or a toothed lug.Connecting to AC Mains Power and Testing Power upCaution Make sure the main power switch located on the rear panel of the PXI-1000 is inthe Off position (0). Refer to Figure 1-2, Rear View of the PXI-1000 Mainframe, fora 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 toall standard worldwide input voltages. Refer to Chapter 1, Getting Started,for power cord specifications. Attach input power through the rear AC inletusing the appropriate line cord supplied. Refer to Figure 1-2, Rear View ofthe PXI-1000 Mainframe, for a diagram of the IEC 320 inlet.Push the main power switch to the On (1) position. Then push the remotepower switch to the On position (if not already on). Observe that all fansbecome operational. Note that the main power switch (rear panel) enablesthe power module to receive AC power. The remote front panel standbyswitch 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 themain power switch on and use the remote On/Off (Standby) switch on thefront to power up and power down the backplane.!
