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 user 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 power source 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 this User's Manual. In case of failure, unusual or
erratic operation of the unit, contact a TDK-Lambda Americas Inc. Sales or Authorized
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 0
to determine if the problem is with the power 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.
