Running Automatic Battery Tests

The automatic discharge test, enabled by default, runs during the transition from Float to Rest mode. After the test completes, the charge cycle restarts to completely charge the batteries and then continues to Rest mode normally. The automatic test runs approximately once every three months and does not run again until after three more Float to Rest mode transitions. If a manual battery test is requested, the automatic battery test timer is reset so it will not run for the next three months.

For an automatic battery test to run:

SThe Automatic Battery Tests setting must be enabled for the automatic battery tests to run. (See the following section, “Configuring Automatic Battery Tests.”)

SThe batteries must be fully charged.

SThe UPS must be in Normal mode or High Efficiency mode with no active alarms.

SThe load must be higher than 10%.

Configuring Automatic Battery Tests

To configure the automatic battery tests:

1Press the button for one second to go to the main menu selection and scroll down to the Settings menu using the button.

2Press the button to enter the Settings menu.

3Use the button to scroll to the Automatic Battery Tests option and press the button. The option begins to flash.

4Select whether to enable or disable the automatic battery test using the and buttons.

5Press the button to confirm.

Configuring Automatic Restart

The UPS automatically restarts if the utility power returns after the output was shut off due to depleted batteries, a shutdown input signal, or automatic shutdown command.

You can set the load segment for the amount of time to delay the restart when utility power returns, using the Automatic Start Delay setting. You can also configure UPS restart to depend on the battery charge level, using the Battery Charge % to Restart setting.
