7 UPS MAINTENANCE
The components inside the UPS cabinet are secured to a sturdy metal frame. All repairable parts and
assemblies are located for easy removal, with very little disassembly. This design allows authorized service
personnel to perform routine maintenance and servicing quickly. You must schedule periodic performance
checks of your UPS system to keep it running properly. Regular routine checks of operation and system
parameters enable your system to function efficiently for many trouble-free years.
7.1 Important Safety Instructions
Remember that your UPS system is designed to supply power
EVEN WHEN DISCONNECTED FROM THE
UTILITY POWER
. The UPS module interiors are unsafe until the DC power source is disconnected and the
electrolytic capacitors are discharged. After disconnecting the utility power and the DC power, authorized
service personnel should wait at least five minutes for capacitor bleed-off before attempting internal access
to the UPS module.
