Before activating the charger:
Inspect the cell connections of the system to ensure that all cells are
connected correctly, POSITIVE (+) to NEGATIVE (-) according to the
assembly drawing.
Measure the voltage across the system terminals. Voltage of the battery
should equal approximately 2.08 times the number of cells in the string.

CAUTION!
It is the sole responsibility of the user to check connections. All connections should be checked at
regular intervals, to ensure the connections are clean and tight. Never operate a battery with loose
or corroded connectors. When restoring connections, disconnect the battery from the load and the
charging equipment and follow the entire precautionary measures outlined in this manual.
8.0 Battery Taps
Connections made to a battery for tapping a certain group of cells to provide a voltage other than the
total battery voltage is not recommended and can void the warranty. Tapping results in an imbalance
of the system during charging and discharging, causing unsatisfactory operation.
9.0 Pilot Cell
Every 6th cell in a battery is usually selected as a pilot cell. It becomes an indicator of the general
condition of the entire battery with regard to voltage, gravity and temperature. Pilot cell readings serve
as an interim indicator between regularly scheduled voltage and gravity readings of the complete
battery.
Because a small amount of electrolyte may be lost in taking hydrometer readings, you should select a
different cell as the pilot cell annually.
Read and record the pilot cell voltage on a monthly basis between regularly scheduled individual cell
readings.
