SECTION 6
MAINTENANCE
6.1 INTRODUCTION
This section provides general maintenance and calibration information as well as replacement
parts lists for the DCS-E Series (3kW) supply.
6.1.1 Units Under Warranty
Units requiring repair during their warranty period should be returned to the manufacturer for
service. Unauthorized repairs performed by any one other than the manufacturer during the
warranty period may void the warranty. Any questions regarding the warranty or any repairs
should be directed to the manufacturer.
WARNING!
Exercise caution when using and servicing power supplies. High energy levels
can be stored at the output voltage terminals on all power supplies in normal
operation. In addition, potentially lethal voltages exist in the power circuit and
the output connector of power supplies that are rated at 40V and over. Filter
capacitors store potentially dangerous energy for some time after power is
removed.
6.2 GENERAL SERVICE AND REPAIR
6.2.1 Periodic Maintenance
Routine service consists only of annual calibration and periodic cleaning. Whenever a unit is
removed from operation, clean it with naphtha or an equivalent solvent for the metal surfaces
and with a weak solution of soap and water for the front panel. Use low pressure compressed
air to blow dust from in and around components on the printed circuit boards.
