Introduction

The T40/T20P Intelligent Charger supports single-phase and three-phase AC power input and can connect with one battery. For compatible batteries, see the Specifications section.
While charging, the charger monitors the status of the battery and can automatically adjust the charging current if required. The intelligent power adjustment function ensures charging can continue even if the ventilation holes are blocked. The charger also boasts a self-diagnostics function. Users can check the status LEDs to confirm if there
are any errors. For more detailed information regarding any errors, users can connect the charger to a remote controller using a USB-C cable and launch the DJI Agras app.
Additionally, the charger includes overcurrent protection, overcharging protection, under-voltage protection, overheating protection, and status display.
The general descriptions in this user guide apply to both the T40 Intelligent Charger and the T20P Intelligent Charger. The T40 Intelligent Charger is used as an example below. The illustrations in this user guide may differ from the actual product.

• When the status LEDs blink for warning or error, connect the charger to the remote controller using a USB-C cable to see more information.
• If any part of the charger is abnormal or damaged, it is recommended to contact a DJI-authorized dealer or DJI Support to repair or replace the part.

Activation
The intelligent charger must be activated before using for the first time. Connect the remote controller to the internet first. Use a USB-C cable to connect to the USB-C connector of the charger and the USB-A connector of the remote controller. Run the DJI Agras app on the remote controller and tap on the upper left corner of the
main interface to enter the charging device interface to activate the charger.

Using the Intelligent Charger

Connecting to Three-Phase AC Power

• Strictly follow the steps described below in order.
• Besides other electrical devices, make sure that the electrical distribution box can provide at least 12 kW of power (at least 16 A of current) for the T40 Intelligent Charger and at least 6 kW of power (at least 16 A of current) for the T20P Intelligent Charger. If you need to connect the charger to a third- party three-phase generator, make sure that the output power of the three-phase generator also meets the corresponding requirements.

1. Turn off the air circuit breaker for the three-phase AC power supply.

2. Rotate and open the cover of the three-phase AC power cable (power supply) and connect the two three- phase AC power cables. Connect the three-phase AC power Cable (charger) to the AC power port of the charger.

3. Connect the intelligent charger to the three-phase AC power supply:
   Connect the three conductors (labeled L1, L2, L3) of the three-phase AC power cable (power supply) to the three hot terminals of the air circuit breaker and the one ground wire (labeled PE) to a grounding terminal of the electrical distribution box.
   •  Only qualified electricians can wire the charger to three-phase AC power and they must wear insulating gloves.
   •  DO NOT connect the ground wire to a neutral terminal or hot terminal.

4. Turn on the air circuit breaker of the three-phase AC power supply.

5. Connect the charger to the battery.
   • If using Agras T40, connect the charging cable to the air-cooled heat sink before putting the battery into the heat sink. The charger starts to charge the battery. The four LEDs of the battery blink in sequence while charging. Remove the battery when the four LEDs turn solid or off and put another battery inside the heat sink to charge.
   • If using Agras T20P, connect the charging cable to the battery directly. The charger starts to charge the battery. The four LEDs of the battery blink in sequence while charging. Remove the battery when the four LEDs turn solid or off and connect another battery to charge.

6. When charging is finished, turn off the air circuit breaker before disconnecting the three-phase AC power cable from the charger.

Connecting to Single-Phase AC Power

1. Connect the two single-phase AC power cables. Connect the single-phase AC power cable (charger) to the charger and then connect the single-phase AC power cable (power supply) to a power outlet.
   • The type of the power outlet may vary depending on the country or region. Choose the appropriate power outlet accordingly.
   • The power outlet should provide at least 16 A of current.

2. Connect the charger to the battery following the same method described in the Connecting to Three-Phase AC Power section.

3. When charging is finished, disconnect the AC power cable from the power outlet and then disconnect the AC power cable from the charger.

Updating Firmware

There will be notifications when firmware updates are available on the DJI website. Pay attention to the Download page of the product on the DJI website to get the latest firmware. Follow the instructions below to update the firmware of the charger using the remote controller.

1. Connect the remote controller to the internet and then connect the charger to the remote controller using a USB-C cable.
2. Run the DJI Agras app on the remote controller and update the firmware by following the instructions.

Storage and Maintenance

Storage
When you are not using the charger, disconnect the charger from AC power and disconnect the charging cable from the battery. Place the charger in a stable place.

• DO NOT place the charger under direct sunlight or in rain or other wet environments.
• Keep the charger away from heat, pressure, water, flammable gases, and corrosives.

Maintenance
Clean the dustproof cover regularly to ensure the heat dissipation performance.

1. Remove the four screws and remove the dustproof cover.
2. Clean the dustproof cover and install it back in place. Install the four screws to secure the dustproof cover.
