Maintenance

The components inside the battery 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 battery 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.
