The components inside the SPM 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 the 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.
