EVSE Protocol Controller 2.0 (EPC 2.0) | Viridian EV

RCM OPERATION
The EPC 2.0 has a residual current monitor function to monitor currents in the system which protects the system in the event
of fault current being detected. The unit is Factory set to trigger at 6mA DC or greater . If this condition arises the EPC 2.0 will
disable charging and indicate a fault condition ( see table below ) .
In order to reset the fault state, the EV and the EVSE need to be disconnected and reconnected.
If the fault current is still present then the device will return to a fault state and disable charging. If this persists then consult
troubleshooting guide.
Important note: RCM not installed
If no RCM device is being used in the EVSE then this functionality needs to be disabled as per the configuration table in this
document, reference section ( 4.1. )
3.5 SELECTABLE
CHARGING CURRENT ( IC )
Selecting charging current on installation
The EPC 2.0 can be configured to restrict the maximum current available to charge the EV on installation of the device . This
is achieved by a fitting a resistor greater than 100
Ω (
See 4.2 for more information ) . If the IC resistor is not fitted the EPC 2.0
will default to the maximum current available either 16A or 32A as selected via the DIP switch ,reference section 4.1
