Connecting the Lithium Battery Supply

Procedure

1. Activate the ESM.
   • Activation through the PWR port: Supply a DC voltage of 43.2–58 V to the PWR port on the ESM panel for at least 5s.
   • Activation through the MANUAL ON/OFF button: Hold down the MANUAL ON/OFF button on the ESM panel for at least 5s and less than 15s.
   • Activation through the power port: Supply a DC voltage of 43.2–58 V to the power port on the front panel for at least 5s.
     1. The MANUAL ON/OFF button is a contact button. The interval for pressing the button should be greater than 0.5s; otherwise, the operation is ineffective.
     2. If the ESM in charge state is deactivated through the MANUAL ON/OFF button, you can only activate the ESM through the MANUAL ON/OFF button. If the ESM in discharge or disconnected state is deactivated through the MANUAL ON/OFF button, you can activate the ESM through the PWR port or power port when the external busbar has no voltage.

2. When multiple ESMs connected in parallel are powered on, observe the RUN indicator on each ESM panel. Communication is normal if the indicator is steady on and is not established if it blinks fast. Check the communications cables between ESMs and rectify the fault.
3. When the ESMs are communicating with the monitoring module, check whether the communication is normal. If the RUN indicator on an ESM is steady on, the ESM communicates properly with the monitoring module. If the indicator blinks fast, the communication is interrupted. In this case, check that the communications cable is properly connected.
4. Observe the ESM for 15 mins. Ensure that it is working properly (the ALM indicator is off and the RUN indicator is steady on).
