ROUTINE MAINTENANCE

The only routine maintenance required for the power 

supply is a thorough cleaning and inspection, with the 

frequency depending on the usage and the operating 

environment.

Warning 

Disconnect primary power at the source before 

removing the cover. Wait at least two minutes before 

opening the cover to allow the primary capacitors to 

discharge.

To clean the unit, remove the screws securing the 

outer cover, lift off the outer cover and use a vacuum 

cleaner to remove any accumulated dirt and dust. The 

unit should also be wiped clean, if necessary; with 

solvents that are recommended for cleaning electrical 

apparatus.
