Connecting an outlet box to the UPS provides three output lines: OUTPUT0, 1, and 2.
You can set ON/OFF delay times for OUTPUT1 and 2, allowing you to control output start and stop. Operation that
utilizes of this function is called “Output line control”.
Ensure that the total capacity of all load devices connected to the system control box does not exceed 1kVA (0.7 kW).
For details, see §10. “Load Devices Connection”.

Use an outlet box if you want to control of the output from the UPS.
When an outlet box is connected, the UPS output consists of the two lines OUTPUT1 and OUTPUT2, which
can be controlled by output line control, and OUTPUT0, which is direct output from the UPS.
The user settings menu allows you to set separate ON/OFF delay times for OUTPUT1 and OUTPUT2. This
makes it possible to start and stop connected load devices in sequence.
As an example of a system configured for power control, the following figure shows a computer and
peripheral devices connected as loads to an outlet box.
