Profinet¶
The Profinet interface supports 10/100 Mbit/s Ethernet. In the Linux operating
system it is available as network interface eth2. The MAC address of this
interface is stored within the OTP of the System on Chip.

Wiring Overview¶
PT1000 Temperature Sensors¶
Fig. 9 Wiring overview for the PT1000 Temperature Sensors¶
This wiring diagram shows an overview of connecting the temperature sensors to the Charge Control Y:
Make sure you only connect PT1000 temperature sensors
Connect sensor 1 between Pin 3 and Pin 5 of MCS
Connect sensor 2 between Pin 4 and Pin 5 of MCS
Connect sensor 3 between Pin 3 and Pin 5 of IO
Connect sensor 4 between Pin 4 and Pin 5 of IO
Emergency Input¶
Fig. 10 Wiring overview for the Emergency Input¶
This wiring diagram shows an overview of connecting the emergeny input to the Charge Control Y:
make sure the emergency input stays between 21.6V and 26.4V for normal behavior
any other voltage is treated as error condition and triggers the safe state
the voltage is measured against Ground (EVSE) (Pin 3)
HV Ready¶
State C is indicated by internally switching HV Ready In (Pin 4, Power & Safety) to HV Ready Out (Pin 5, Power & Safety). The short between HV Ready In to HV Ready Out is only done while the vehicle indicates state C AND Charge Control Y detects no safety issues.
