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

Remember that your UPS system is designed to supply power EVEN WHEN IT IS 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 must wait at least 5
minutes for capacitor bleed-off before attempting internal access to the UPS module.
