UPS (3–18 kVA) User's Guide S 164201393 Rev E www.eaton.com/powerquality

Parameters

The parameters describe the UPS operation. Some useful parameters

are input and output voltage, input and output current, and battery

voltage, among others. Some are operator‐adjustable, such as the

local date and time and various operating limits. All parameters are

password-protected. Although every operating condition and parameter

is accessible through the front panel display, you may change a value

only if you have entered the correct password.

NOTE After 10 minutes of inactivity, the UPS automatically deletes any active password

level and returns to the normal running display.

Changing Parameter Settings

Changing an operating parameter is similar to setting initial parameters,

as described in “Initial Startup Parameters” on page 74:

1. Use the Menu map (Figure 60 on page 88) to find the parameter

you need to change, and move through the menu structure until the

parameter name appears on the display.

2. Press the

button to access the parameter value. The Enter

Password screen automatically opens if permission is required for a

particular parameter.

3. Enter the appropriate password, if applicable, and then change the

parameter value.

4. Press the

button again to save the change. To not save the

change, press ESC instead of the

button.
