Detailed Operating Instructions
1)
To use your BatteryMINDer with FAA certified aircraft, a wiring harness must be installed to
provide a convenient electrical connection between the aircraft’s lead acid battery and the
charger. Your GPU/Charger includes a kit of aviation-grade components for this purpose, Model
BM-AIK1 Airframe Interface Kit. Provide this kit to your FAA licensed aircraft mechanic for
installation. It contains the parts to fabricate and install a fused wire harness from your aircraft
battery to a polarized plug with insulating dust cover. The plug should be mounted in a
convenient location for connecting the BatteryMINDer’s output cable. The kit also includes
regulatory references to assure your mechanic that this qualifies as a minor alteration and is
within his/her authority to install and return-to-service with a simple airframe maintenance log
entry. No FAA 337 required, or should be filed.
2)
Attach the GPU line cord and connect to a 120VAC receptacle. A heavy-duty extension cord may
be used if necessary, but the shorter the better.
3)
Attach the charger output cable to the twist-on receptacle on the GPU front panel.
4)
Verify GPU power switch is in the OFF position.
5)
Attach output cord of charger to the mating airframe connector.
