overcharging. The charger may be left in this stage for lengthy periods of time without
attention (though periodic checks of electrolyte level in flooded batteries is recom-
mended). It is not necessary or recommended to shut the charger off when this stage is
reached.
A typical three stage charging cycle is illustrated in FIGURE 3.

A WARNING ABOUT THE CHARGE CYCLE SELECT SWITCH: Whenever a load of ap-
proximately 3 amps or more is applied, the charger will go into the elevated voltage
"Charge" mode, as indicated by the glowing red indicator on the front panel. (See
specifications for actual charge/float voltages.) Battery electrolyte may be damaged
or lost by extended exposure to this higher voltage. If there is a d.c. load on the
battery system of 3 amps or more for periods lasting 8 hours or more, it is strongly
recommended that the Charge Cycle Select switch on the front panel be placed in the
"Float" position.
B) Start Up
1) Before powering up your charger, check for tight electrical connections to each bat-
tery in your system. Switch off any d.c. loads on the batteries. Apply a.c. power. Observe
the Charger Status indicator on the front panel. If it glows red and stays red for a while,
it is an indication that the batteries are in a relatively low state of charge. The charger,
sensing this, is supplying high current to the batteries. If the indicator glows red briefly,
then switches to green it is an indication that the batteries are at or nearing full
charge, and the charger has switched to the "Float" (maintenance) mode.
2) After the indicator has switched to green, apply a load to the charger by switching on
some lights, a pump or some other d.c. appliance. Observe the indicator. As current is
demanded from the battery system, the charger will automatically increase its output in
response to the increased load demand and the charger will switch to the higher cur-
rent (and higher voltage) "Charge" mode. As long as the load current exceeds approxi-
