Section 300: Operation
This section will describe how FERRUPS works. We’ll discuss the meaning of the front panel lights and describe
how to use the control panel. We’ll also describe what the automatic system test does, what each alarm means,
what parameters are, and how to read the Alarm and Inverter Logs. Finally, we’ll see how to turn off FERRUPS.
301 Front Panel Lights
At the front of your FERRUPS is a panel with five lights (LEDs). These lights tell you several things about the
