ALPHA C-25 Manual V2.1.doc Page 7
The rear of the unit has air flow for cooling. Allow at least 6" (150 mm) of
separation from the wall and adjacent equipment in order to maintain proper
air flow.
NOTE: In non air-conditioned rooms it is recommended
that circulating or extracting fans be used to aid in the
removal of heated air.
NOTE: Operation in dusty or otherwise dirty air
environments will severely reduce the cooling capacity of
the fans and can lead to premature failure.
3. OPERATING GUIDE
This section gives an overview of how to charge a battery using the Alpha C-25. Always
refer to the battery manufacturers’ maintenance manual for their recommended
charging methods and settings.
3.1 CHARGE CHARACTERISTICS
The constant current charge characteristics of a lead-acid cell with respect to cell
voltage, ampere-hours input, specific gravity and rate of gassing at constant
current can be seen in figure 3-1.
