Fault Monitoring Connection to 12V LED
The table below shows the recommended user alerts based on voltages when in flight. The
low charge level is very different from a lead acid battery, for a lithium battery is completely
drained at approximately 11.5V.

Vent Tubing Installation (ETX900-VNT)
The ETX900-VNT includes a thermal run-away containment system making it fully compliant to
DO-347 specification. The containment system includes vent tubes designed carry vapor or smoke
to the exterior of the aircraft in the event on a thermal run-away condition. Follow the below
guidelines for properly installing vent tubes.
•
Route the vent tubes to the outside of the aircraft or a compartment sealed-off from
the passenger cabin that is vent to the outside.
•
Secure the vent tubes within 12” of the battery and the aircraft exit
•
Be careful not crush or restrict flow through the tubing.
•
The minimum bend radius is 3”;
tighter bends could cause the tubing to kink.
•
Only EarthX approved or supplied tubing should be used. The tubing is chemical
resistant and rated for 500°F
(1/4” ID, 5/16” OD Teflon tubing)
.
