If a ground fault error or an EV connection error has been detected:
1. Remove the EV connector from the vehicle.
2. Inspect the connector and the vehicle charge port. Be sure they
are clean and undamaged.
3. Reconnect to the vehicle. If the fault condition persists, a
problem may exist on the vehicle.
4. Refer to the vehicle owner's manual for instructions on
inspecting and cleaning the charge port.
5. Plug the EV connector back into the vehicle.
6. If the ground fault error is still detected, contact a Customer
Service Representative for assistance.
Ground Missing: Turns on when the unit has detected a missing
Service Ground. CS 3-Phase will not close the contactor until a
proper Service Ground has been connected. The front panel Red
PROTECTION light will turn on, and the Diagnostic LED will
flash at a faster rate.
NOTE If a missing ground is discovered, power should be
turned off before re-connecting the ground. If ground
is reconnected without turning off the power, it will be
necessary to wait 5 minutes for the CS 3-Phase to clear
the Ground Missing error. Table 2 below illustrates the
information that can be obtained from the 4 LEDs on the
PC board.
