INTRODUCTION

4.1
This chapter contains preventive maintenance information for the SPS-A
Series power supplies.
WARNING!
All maintenance that requires removal of the cover of the unit should only
be done by properly trained and qualified personnel. Hazardous voltages
exist inside the unit. Disconnect the supply from the input power before
performing any maintenance. Service, fuse verification, and connection of
wiring to the chassis must be accomplished at least five minutes after
power has been removed via external means; all circuits and/or terminals
to be touched must be safety grounded to the chassis.

PREVENTIVE MAINTENANCE

4.2
No routine maintenance on the SPS-A Series is required, aside from
periodic cleaning of the unit when needed:
•
Once a unit is removed from service, vacuum all air vents,
including the front panel grill. Clean the exterior with a mild
solution of detergent and water. Apply the solution onto a soft
cloth, not directly to the surface of the unit. To prevent damage to
materials, do not use aromatic hydrocarbons or chlorinated
solvents for cleaning.
•
Low–pressure compressed air may be used to remove dust from
in and around components on the printed circuit boards.
WARNING!
The OFF position of the power switch does not remove voltage from the input
terminal blocks. Remove all external power before performing any service.
