CONNECTION
Make sure to use the correct power cable for your application. First, engage and lock the
male XLR connector on the power cable to the correct output connector on the EC-90.
Second, connect the mating end of the power cable to the intended device. You are now
ready to turn on the device and begin using the EC-90.
COMPATABILITY
To avoid compatibility problems, the XLR output connectors are configured differently
for each voltage. The 12 volt ouput is configured as industry standard pin 1 ground, pin
4 positive. All existing Eco-Charge 12 volt cables are compatible with the EC-90. The
regulated output connector is configured differently to prevent voltage mismatching. This
new wiring configuration requires a jumper in the power cable XLR connector to activate
the regulator circuit. The following diagrams indicate the pin configurations of all EC-90
batteries.
