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.  
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.  
Removal  
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.  
Installation  
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.
