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.
Schedule periodic performance checks of your UPS system to keep it running properly. Regular routine checks
of operation and system parameters will enable your system to function efficiently for many trouble –free
years.

the voltage within the battery string. DDOO NNOOTT AATTTTEEMMPPTT TTOO AACCCCEESSSS AANNYY IINNTTEERRNNAALL AARREEAA OOFF TTHHEE
