Falcon ED3000-A - Manual (Page 11)

To escape this condition, the problem must first be corrected then
turn the ED power switch "OFF", then back "ON".
For models supplied with batteries it is recommended that you
leave the ED unit power switch "ON" at all times and switch your
devices "OFF" individually. This will ensure that your batteries are
always at a maximum charged state.
The power switch acts as a system ON/OFF switch. When this switch is
turned "OFF", power is lost to the entire unit including all outlets at the
rear of the ED.
