CHAPTER 10: MAINTENANCE
10.1 Introduction
This chapter provides information about maintenance, calibration and troubleshooting.
10.2 Units Under Warranty
Units requiring repair during the warranty period should be returned to a NI authorized service
facility. Unauthorized repairs performed by other than the authorized service facilities may void
the warranty.
10.3 Periodic Maintenance
No routine maintenance of the power supply is required except for periodic cleaning. To clean,
disconnect the unit from the AC supply and allow 30sec. for discharging internal voltage. The front
panel and the metal surfaces should be cleaned using a mild solution of detergent and water. The
solution should be applied onto a soft cloth, and not directly to the surface of the unit. Do not
use aromatic hydrocarbons or chlorinated solvents for cleaning. Use low pressure compressed
air to blow dust from the unit.
10.4 Adjustments and Calibration
No internal adjustment or calibration is required. There is NO REASON to open the power supply
cover.
10.5 Parts Replacement and Repairs
As repairs are made only by the manufacturer or by authorized service facilities, no parts
replacement information is provided in the manual. In case of failure, unusual or erratic operation
of the unit, contact the NI sales or service facility nearest you.
10.6 Troubleshooting
If the power supply appears to be operating improperly, use the troubleshooting guide to determine
whether the power supply, load or external control circuits are the cause.
Configure the power supply for basic front panel operation and perform the tests listed in Section
3.8 to determine whether the problem can be found with the power supply.
Table 10-1 provides the basic checks that can be performed to diagnose problems, and references
to relevant sections of this manual for further information.
