IMPORTANT: The onsite service connection
must be properly identified
before installation of the EVSE.
If you are unsure of the available
service connection, consult
the local utility company or
contact Bosch Electric Vehicle
Solutions at 1-877-805-EVSE
(3873).
NOTE: The L1, L2, and Ground outputs (H, N for Eu-
rope) in the following illustrations correspond to
the inputs on the
EVSE
.
NOTE: For the (earth) ground connection, always con-
nect the neutral at the service panel to earth
ground. Ground fault protection is not possible
unless the neutral (center tap on the service
transformer) is connected to an earth ground.

of a 3-phase feed. Only three wires are
connected, take care that the service
transformer secondary connection is
known, and the three wires from the
main-panel circuit breaker are correctly
connected and labeled.

America)
Any two of the legs can be used to provide 208V to the
