NI PXIe-1062Q Power Supply Shuttle

The NI PXIe-1062Q power supply shuttle is a replacement part for the NI PXIe-1062Q chassis.

Caution This power supply is not compatible with any other National Instruments chassis.

Introduction

To minimize downtime caused by a power-supply failure, the NI PXIe-1062Q chassis has a modular power supply shuttle. This power supply shuttle includes the chassis power supply, cooling fans, and fan-control circuitry. Key features of the power supply shuttle include:

• Universal AC input with automatic voltage and frequency ranging

• Over-current protection via push-reset circuit breaker

• Remote power monitoring and inhibit via a rear-panel connector

• Temperature-sensing module that can adjust fan speed based on air-intake temperature to minimize audible noise

• Circuitry to control a front-panel LED that indicates power supply failure

Unpacking

Carefully inspect the shipping container and the power supply shuttle for damage. Check for visible damage to the metal work. Check to make sure all handles, hardware, and switches are undamaged. Visually inspect the inside of the shuttle for any possible damage, debris, or detached components. If damage appears to have been caused during shipment, file a claim with the carrier. Retain the packing material for possible inspection and/or reshipment.

Installation and Maintenance

The information in this section is for qualified service personnel only. Read the Read Me First: Safety and Radio-Frequency Interference document included with your kit before using the power supply shuttle.

Caution Many components within the NI PXIe-1062Q chassis under repair are susceptible

to static discharge damage. Service the chassis only in a static-free environment. Observe standard handling precautions for static-sensitive devices while servicing the chassis. Always wear a grounded wrist strap, or equivalent, while servicing the chassis.

Caution Always disconnect the AC power cable before cleaning or servicing the chassis.

Caution Never connect the AC power cable to the power supply shuttle until you install it

in a NI PXIe-1062Q chassis. Do not use, test, or configure the power supply shuttle outside of a chassis.

Removal

Installation

The power supply shuttle is a replacement part for the NI PXIe-1062Q chassis. The NI PXIe-1062Q User Manual contains all of the most up-to-date chassis service procedures, including removal and replacement of power supply shuttles. The chassis includes a hardcopy of the NI PXIe-1062Q User Manual; additionally, you can download a softcopy from

ni.com/support.

Before attempting to replace the power supply shuttle, verify that there is adequate clearance behind the chassis. With the chassis powered off, disconnect the power cable from the power supply shuttle on the back of the chassis. Identify the eight mounting screws that attach the power supply shuttle to the chassis. Refer to Figure 1 for the mounting screw locations. Using a Phillips screwdriver, remove the mounting screws. Pull on the two rear handles of the power supply shuttle to remove it from the back of the chassis.

Ensure that there is no visible damage to the new power supply shuttle. Verify that the housing and connector on the new power supply shuttle have no foreign material inside. Remove the protective cap on the PXI_CLK10 connector. Install the new power supply shuttle into the opening on the rear of the chassis. Install and tighten the eight mounting screws with a Phillips screwdriver.

Configuration

The fan-speed selector switch is on the rear panel of the power supply shuttle. Refer to Figure 1 to locate the fan-speed selector. Select HIGH for maximum cooling performance (recommended) or AUTO for quieter operation. When set to AUTO, air-intake temperature determines the fan speed.

Connecting Safety Ground

Caution The power supply shuttle is designed with a three-position NEMA 5-15

(IEC 60320) jack 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. Refer to Figure 1 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.
