Powerware 9335 operation manual UPS Operational Controls, Control Panel, System and Load ON/OFF

6.2 UPS Operational Controls

The UPS has many standard features that provide cost effective and consistently reliable power protection.

6.2.1 Control Panel

The Control Panel on the front of the UPS, pictured in Fig. 6–2, contains a LCD screen to display the current status of the UPS system. You can view a statistical history and log of system events and display a real-time representation of power flow through the system components. LED status indicators show the operating mode of the UPS and alert you to system events. Panel push buttons provide navigation through the information and control screens. The load ON/OFF pushbuttons are located at the right of the control panel. Both must be pressed simultaneously to activate the LOAD ON/OFF function. Below the LCD screen are the user control pushbuttons, RESET, UP, DOWN, and ENTER, which provide access to the control and measurement functions of the UPS. The control panel is described in detail in chapter 7, “Using the Control Panel”.

6.2.2 System and Load ON/OFF

Two load ON/OFF pushbuttons are located on the right side of the LCD display. Activating both pushbuttons simultaneously will effect immediate system shutoff. This feature prevents accidental system shutdown if one of the pushbuttons is inadvertently depressed. System turn on is achieved in the same manner, by simultaneously depressing both buttons. Operation of the system ON/OFF pushbuttons is described in detail in Chapter 7, “Using the Control Panel” and Chapter 8, “UPS Operating Instructions.”
