Installation Requirements
Assemble Flex Charger
There are two different ways to assemble the Flex charger.

Operation
Operating Instructions
Operating the Flex Charger

The Flex Charger is designed for a mains voltage/frequency range of 100V to 240V and 50Hz to 60Hz.
Connect the charger to the mains power. When the charger is connected to the mains supply, the power indicator glows green.
Insert the Li-ion battery into the charging station. Charging starts automatically as soon as the battery is inserted. The charging time depends on the charge state and capacity of the Li-ion battery.
Interconnect Chargers
The Flex charger has built in interconnection. The maximum number of chargers interconnected is limited, depending on the output voltage of the power supply.
Maximum 4 chargers at 100VAC (Japan)
Maximum 5 chargers at 110-120VAC
Maximum 10 chargers at 240VAC
This includes the master charger, that is connected to the alternating current (AC) grid.
Battery Health and Charge Display
When the charger is connected to a battery, the state of health (SOH) and the state of charge (SOC) will glow for 5 seconds before starting the charge pattern.
Battery State of Health
Battery health is shown by the outline of the battery indicator.

Battery light | Battery health | Remark |
---|---|---|
Green | Good | Battery is healthy and performing well |
Yellow | Decreased | Battery will eventually need to be replaced |
Red | Low | Replace the battery |
Battery State of Charge
The battery charge is shown by the bars in the battery indicator and shows 5 levels:

Level | Battery bar indicator | Battery status | Remark |
---|---|---|---|
1 | 3 white | Full charge | |

Repair Instructions
Changing Adapter on the Charger

Upgrading the Charger Software
Copy the software file to an empty USB memory and make sure the file name is ACTA_FW_.BIN.
If the file name is incorrect, the software upgrade will not be performed.
Disconnect the charger from the power outlet and await the green power LED indicator to turn off (this will take approximately 30 seconds).
Unscrew and remove the battery adapter on top of the charger.
Connect the USB memory to the charger's USB port (positioned on top of the charger).
Connect the charger to the power outlet.
The software will now be automatically upgraded. While the upgrade is in progress the state of health (SOH) LED indicator is flashing white. The upgrade procedure takes a few seconds.
When the upgrade is finished the state of health (SOH) and the state of charge (SOC) LED indicators are lit with a steady white light for a few seconds, and then turns off.
Disconnect the charger from the power outlet and await the green power LED to turn off (this will take approximately 30 seconds).
Disconnect the USB memory.
Reattach the battery adapter and fasten the screws.
Connect the charger to the power outlet. The charger is now ready to operate.
