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 TDK-Lambda
Americas Inc. authorized service facility. Refer to the addresses listing on the back cover of
this manual. Unauthorized repairs performed by other than the authorized service facilities
will 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 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.
10.4. 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.
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 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.
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 circuit are the cause.
Configure the power supply for basic front panel operation and perform the tests of Section
3.8 to determine if the problem is with the supply.
Table 10-1 provides the basic checks that can be performed to diagnose problems, and
references to Sections of this manual for further information.
