  7. When the target SOC is reached, the tool automatically stops the discharging operation and opens the contactors. The discharging operation can be manually stopped by pressing the Stop button in the software application. Note: The emergency stop switch on the charger/interface box can be used to immediately open the contactors in an emergency. Do not press the emergency stop switch except in an emergency, as it opens the contactors under load and disconnects power to the BMS, causing the Charger/Discharger Tool to lose communication with the BMS.

  9. Wait until the voltage displayed on the HV DC Link Voltmeter is less than 5V, then shut down the PC.
