To be EV-ready compliant, one of the requirements is that the EV charger can execute an emergency stop in case of
contactor failure. In order to execute an emergency stop, the circuit breakers of the Green Motion Building EV charger
need to be equipped with a tripping coil/shunt trip, a device designed to switch the circuit breakers off remotely. The
shunt trip should have a DC voltage rating of 24 V and should be connected on the supply lead control wire, connected
to the E terminal of the EV charger. See the wiring diagram in Figure 11. The installation process should be done by an
EV-ready certified installer and following the requirements listed in this section.
