GX
Series of chargers represents some of the most innovative
and advanced technology on the market, making each
charge simple and easy. The GX is designed for charging all
types of 24V, 36V or 48V lead-acid and lithium-ion battery
systems, including Wet (Flooded), Gel, MF (Maintenance-
Free), CA (Calcium), EFB (Enhanced Flooded Battery), AGM
(Absorption Glass Mat), and LIB (Lithium Ion) batteries. It
is suitable for charging battery capacities from 25 to 500
Amp-Hours and maintaining all battery sizes.
Getting Started.
Before using the charger, carefully
read the battery manufacturer’s specific precautions and
recommended rates of charge for the battery. Make sure
to determine the voltage and chemistry of the battery by
referring to your battery owner’s manual prior to charging.
Mounting.
The GX Series Chargers have four (4) external
holes for mounting. Make sure there are no obstructions
behind the mounting surface. It is important to keep in mind
the distance to the battery. Allow for 12-inches (304mm) of
slack in cables between connections.
Charging Modes.
The GX Series Chargers have seven
(7) modes: Standby, NORM, COLD/AGM, AGM+, LI-ION,
REPAIR and SUPPLY. Some charge modes must be
pressed and held for three (3) seconds to enter the mode.
These “Press and Hold” modes are advanced charging
modes that require your full attention before selecting. It
is important to understand the differences and purpose
of each charge mode. Do not operate the charger until
you confirm the appropriate charge mode for your battery.
