4.4 External devices
4.4.1 Key input
KEY input A3 (A1) is generally connected to the vehicle start key switch. It
supplies battery voltage to the logic circuitry and it also pre-charges the DC-link
capacitors at key-on, before main contactor closes. The KEY voltage is
monitored.
 Note: external loads connected to the power terminal +B, such as proximity
switches, load the internal PTC resistor along the key input path, with the
consequence that the pre-charge voltage may be lower than expected.
