Use
1. The charger must be well grounded when in use. Please use a grounding wire to ground the shell of
the charger. Remove the screw of the grounding interface and fix the grounding wire, as shown in the
figure below.
2. Connecting the charger to household electricity or a generator.
3. Insert the charging cable connector into the battery to start charging.
The AC end of the charger is equipped with two power input sockets.
1) In a home environment, make sure that the socket and wiring power support 7000W. It is
recommended to use a single plug. The charger will automatically determine and charge with a low
power of 3000W to avoid the danger of overloading the home grid due to excessive current.
Charging time is about 30 minutes.
2) For generators of 9000 watts or more, the charger will charge the battery with the power of 7000
watts when plugged into the input power socket. Charging time is about 11 minutes.
The charger interface can be connected to two household circuits at the same time, one household
circuit and one generator, or two generators. When the two sockets are used at the same time, the
charging power is superimposed, and make sure the power of the wires and sockets of household
circuits are greater than 7000W.
Before connecting the charger, make sure various ports and input harnesses of the charger are not
cracked, chipped, blocked, or misshapen.
Before charging, make sure the battery is not cracked, chipped, or misshapen, and the port is not
blocked.
4. When charging is completed, unplug the charging controller from the battery before unplugging the
power supply cable.
