B1. FLOAT VOLTAGE SELECTION
These fine tuned selections of float voltages enable the best voltage level for maximum battery life. Choose 27.6V when in doubt
or in Power Supply Mode.
Follow the markings on Deep Cycle batteries of the Standby float voltage.
B2. Recommended Battery Capacity
The following minimum AH capacities are a generalized suggestion, some batteries can take higher charge current, check with
battery manufacturers for charging batteries with smaller capacity.

C. Battery Charger Installation and Connection
Observe the warnings & safety precautions before rushing to install and operate the charger.
Check battery condition, fill up cells for wet battery, clean battery poles.

Negative – terminal and the Negative – Pole of the battery.
Make sure all the connections are secured and well tighten up, double check on the correct polarity.
Double check again for correct selection of Slide Switch 1 at Charger Mode, Switch 2 for Battery type and Switch 3 for Float
Voltage setting value.
