CHAPTER 9 MAINTENANCE
9.1 INTRODUCTION
This Chapter provides information about maintenance, calibration and troubleshooting.
9.2 UNITS UNDER WARRANTY
Units requiring repair during the warranty period should be returned to a TDK-Lambda Americas Inc.
authorized service facility. Refer to the addresses listing on the back cover of this manual. Unauthor-
ized repairs performed by other than the authorized service facilities will void the warranty.
9.3 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 60 seconds for discharging internal voltage. The front
panel and the metal surfaces should be cleaned using a damp cloth containing 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 hydocarbons or chlorinated solvents for cleaning. Use low pressure
compressed air to blow dust from the unit.
9.4 ADJUSTMENTS AND CALIBRATION
No internal adjustment or calibration is required. There is NO REASON to open the power supply
cover. This will void the warranty.
9.5 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
a TDK-Lambda Americas Inc. sales or service facility nearest you. Please refer to the TDK-Lambda
Americas Inc. sales offices addresses listing on the back cover of this user manual.
9.6 TROUBLESHOOTING
If the power supply appears to be operating improperly, use the troubleshooting guide to determine
whether the power supply, load or external control circuit are the cause.
Configure the power supply for basic front panel operation and perform the tests of Section 3.8 to de-
termine if the problem is with the supply.
Table 9-1 provides the basic checks that can be performed to diagnose problems, and references to
Sections of this manual for further information.
