Part 4: Operation in Charger Mode
To operate the PROsine in Charger mode:
1. Turn on the PROsine’s ON/OFF/REM switch.
2. Connect AC shorepower.
• The batteries are charged according to the three-step algorithm you have
selected.
• The READY LED comes on when the charge cycle is complete.
• You can interrupt the charge cycle any time if you don’t have time to wait
for a full charge.
• To maintain optimal performance in flooded batteries, an occasional
equalize cycle may be required.
3. While the batteries are being charged, you can monitor which stage they are in
by viewing PROsine System Mode on the PROsine—Diagnostics menu.
See page 4–17.
Operation in Equalization Mode
WARNING: Explosion hazard
Review the “Important Safety Instructions” on page vii before operating the PROsine.
During charging, batteries may generate explosive gasses. Thoroughly ventilate the area
around the batteries and ensure that there are no sources of flames or sparks in the vicinity.
Study all battery manufacturer’s precautions such as removing or not removing cell caps
while charging and recommended rates of charge.
Important:
If you are charging a non-sealed battery, add distilled water to each cell
until battery acid reaches the level specified by the manufacturer. This helps prevent over-
heating and purges excessive gases from the cells. Do not overfill. For a battery without
cell caps, follow the manufacturer’s recharging instructions carefully.
WARNING: Explosion hazard
Equalization generates explosive gases. Ensure adequate ventilation.
CAUTION
Sealed lead-acid batteries and gel batteries must NEVER be equalized or premature
battery failure will result. Equalize mode is disabled if you have selected “Gel” as the
Battery Type.
Only flooded lead-acid batteries should be equalized. As a general rule, do not equalize a
battery unless there are provisions to add water to it and the manufacturer recommends
equalization.
