Maintaining The Ups System; Important Safety Instructions - Eaton Powerware 9315 Operation Manual

Chapter 8
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 many trouble-free years.

8.1 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 five minutes before
attempting internal access to the UPS system.
