SECTION 5
MAINTENANCE
5.1 INTRODUCTION
This chapter contains preventive maintenance information for the SFA 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.
5.2 PREVENTIVE MAINTENANCE
No routine maintenance on the SFA 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.
