5 UPS operating instructions
This section describes how to operate the UPS.
NOTE
Before starting the UPS, ensure all installation tasks are complete and a preliminary startup
has been performed by authorized service personnel. The preliminary startup verifies
all electrical interconnections to ensure the installation was successful and the system
operates properly.
NOTE
Read this section of the manual and have thorough knowledge of UPS operation before
attempting to operate any of the controls.
NOTE
The UPS displays two minutes of battery runtime at the initial startup. After a 24-hour
charging period, the UPS automatically runs a battery test and the correct battery runtime
displays.
