change the fuses, use a screwdriver to loosen the screws and remove the fuses.
Always replace the fuses with the same type and rating. After inserting the new
fuses, tighten the screws firmly. DO NOT OVERTIGHTEN.
4.0 Charge Controller Options
4.1 GPC Charging
The optional GPC allows the GPC to operate as an automatic three-stage smart
charger giving the customer the benefit of a Bulk, Absorption, and Float stage
charging. The charging capacity of the GPC is increased, charge times are
decreased, proper and safe battery charging is ensured, and overcharging is
minimized. The GPC monitors the battery at all times. If the GPC voltage remains
in the float stage for more than seven days, the GPC automatically delivers a
boost charge as a 4
th
stage called equalize for a predetermined time, then
automatically returns to the normal float stage. The GPC is recommended for
flooded batteries only.
4.1.1 Reduced Charge Times
The Bulk stage allows the batteries to be charged from the full rated load of the
battery. During this stage the batteries are recharged quickly to reduce charge
times.
4.1.2 Increased Battery Capacity
After the Bulk stage, the batteries are held in the Absorption stage for a
controlled period, ensuring a full and complete charge.
4.1.3 Reduced Battery Stress
During the Float stage, the GPC charge voltage is reduced. This minimizes
gassing while maintaining a full charge at the nominal rate of the battery.
4.1.4 Weekly Equalization for Longer Battery Life
If the batteries have not received a smart charge during a seven-day period, the
GPC initiates an equalization stage to top off the batteries, dissolving any sulfate
on the battery's internal plates and avoiding stratification.
