Flexcharge NC25A-12 - IMPORTANT INFORMATION

Page 2 of 24
IMPORTANT INFORMATION
THE NC25 CONTROLLER IS AN "ON/OFF" REGULATOR NOT A CONSTANT VOLTAGE
REGULATOR, AND THEREFORE IT CANNOT BE TESTED BY SIMPLY MEASURING THE OUTPUT
VOLTAGE ON THE TERMINAL STRIP OF THE CONTROLLER. THE CONTROLLER MUST BE
CONNECTED AS SHOWN IN ONE OF THE SCHEMATICS BEFORE IT WILL REGULATE.
READ ALL OF PAGES 5 through 8 OF THIS MANUAL TO LEARN HOW THE CONTROLLER
REGULATES BEFORE CONCLUDING THAT YOUR CONTROLLER IS NOT REGULATING.
All wire to wire and crimp connections must be
soldered for this, or any charge controller to
operate dependably.
Do not solder on the controllers terminal block.
The terminals on the controller are coated with an
anti corrosion coating.
