Maintaining the UPS System
The components inside the UPS cabinet are secured to a sturdy metal
frame that is supported by the UPS magnetics. This design allows authorized
service personnel to remove repairable components with very little disassembly.
All repairable parts and assemblies are located in the front of the UPS, allowing all
routine maintenance and servicing to be performed with front panel access.
You must schedule periodic performance checks of your UPS to keep it running
properly. Regular routine checks of operation and system parameters will enable
your UPS system to function efficiently for manytrouble-free years.

Important Safety Instructions

Remember that your UPS is designed to supply power EVEN WHEN
DISCONNECTED FROM THE UTILITY POWER. The UPS interior is 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 5 minutes before attempting internal access to the
UPS system.
WARNING:
Servicing and maintenance should be performed by qualified service personnel
only.
