Serial connection with USB port
Serial connection through use of the inverter's USB port allows connection of a single
inverter to a personal computer equipped with a USB 2.0 interface and dedicated
software supplied by Power-One. The PC-inverter connection cable is a standard USB
2.0 cable, 5 meters long, with terminals of the A and B type. Just remove the
waterproof plug located on Aurora's side to make the connection (see Fig. 26).

Alarm contact connection
Three connections are provided to drive an external alarm: a common contact, a
normally open contact and a normally closed contact. To cable alarm contact use a
three-wire or two-wire cable. The cables are routed through the hole located on the
bottom of the Switch box which is blanked with waterproof plugs (see Fig. 23 -23a).
Refer to 3.3.7 for correct cabling procedure.
