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."
