3.1Operator Controls

The Npower operator controls and indicators are located on the UPS Module Cabinet door and inside the cabinet. See Figure 2. The Operator Control Panel is located in the upper lefthand corner of the door, enabling the Operator to quickly identify the current status of the UPS system and to perform most of the manual operations. The operator display screen is driven by an easy-to-follow menu- prompted software program. The internal control system executes programs which generate mes- sages on this display screen. Screen messages instruct the Operator during start up, operation, and shutdown. The screen also displays status information upon request. Operating the UPS consists of watching the indicators on the operator control panel and making appropriate responses. Further UPS monitoring and testing is achieved by navigating through a series of menu selections on the dis- play screen.
