The CAN / Pilot signals are transmitted via a 4 -wire cable bundled with the output charge cables.
Connector auxiliary connections as viewed from the end of the battery cable (pictured to the right).
One of the features of this type of communication is that it acts as an arcless disconnect protection circuit. If loss
of the CAN or Pilot signal are detected, the charger will quickly shutdown.
If the small pins become disconnected, the current will stop. If they are pulled while on charge, the charge will be
stopped before a full DC disconnect of the euro connectors.
If a communication cable lead gets disconnected while charging, the charger will shutdown due to the loss of
communication or heartbeat.
