Installation
The instruction given here is generic and is NOT the sole installation instruction for a
particular aircraft. Appendix B has a block diagram of a typical installation. For a specific
aircraft, refer to the documentation listed in the Appendix of the Instructions on Continued
Air Worthiness (ICA) manual.
Remove all metal objects from your person before handling the battery and use insulated tools for
installation.
The power terminals are ALWAYS live. Do not short across the terminals. Use caution when
handling the battery inside the aircraft around metallic structures.
Battery Installation Location
The battery is designed to be mounted in a variety of locations within the aircraft including the
engine compartment, baggage compartment or cabin as long as the environmental condition in
those locations do not exceed the battery’s specifications (see the specifications section and
environmental qualification section of this manual). The battery can be mounted upright or on its
side.
Battery Installation
Lithium Iron Phosphate batteries are very robust, but if mishandled or misused they can
rupture and they can burn. Never disassemble the battery or disable the built-in Battery
Management System (BMS). It is recommended you check the voltage before installing. If
the voltage is below 26.4V, charge the battery before installing. Follow these steps to
properly and safely install your new ETX Lithium battery.
1.
Remove the old battery, while paying attention to the routing and placement of
wires, cables and protective covers.
2.
Check the battery cables and connectors for corrosion or damage. Pay special
attention to the positive battery cable (red cable), checking for cuts or wear marks in
the insulation. Clean and or replace the battery cables as required.
3.
Mount the battery in an approved battery box or the existing battery box with the
approved spacer (see Appendix for specific instructions).
4.
Connect the positive (red) cable first. Make sure the Phillips screw is securely
fastened (45in-lbs), but do not over-tighten. Next, connect the negative (black)
cable. Do not connect the battery in reverse polarity (positive to negative or
negative to positive).
5.
Re-install the battery holder or strap and tighten securely. Re-secure all the wires and
cables with zip-ties or other fasteners. See specification section above for battery
