WARNING: Only a qualified electrician should perform the installation. The
installation must be performed in accordance with all local electri- cal codes
and ordinances.
AVERTISSEMENT: Seul un électricien qualifié doit effectuer l'instal- lation.
L'installation doit être effectuée conformément à tous les codes électriques
locaux et des ordonnances.
Only 3 wires are connected, but care must be taken that the service transformer
secondary connection is definitely known, and the 3 wires from the main circuit breaker
panel are connected and labeled correctly. Figures 2, 3, and 4 below show the most
common service transformer secondary wiring formats.
Notice that L1, L2, & Ground are labeled on each diagram. Those transform- er outputs
correspond to the same inputs on the EV. Also, each of the two
3-phase diagrams shows an L3 output, which is not used. Do not connect all
three phases of a 3-phase secondary to the EV. This is a single-phase device.
The Neutral at the service panel must be connected to Earth Ground somewhere in the
system on any of the three connection arrangements. Ground-fault pro- tection is not
possible unless the Neutral (center-tap on the service transformer) is connected to an
Earth Ground. If no Ground is provided by the electrical ser- vice, a grounding stake
must be driven into the Ground nearby, following local electrical codes. The grounding
stake must be connected to the ground bar in the main breaker panel, and Neutral
connected to Ground at that point.
WARNING: Local electrical codes must always be followed when
installing the grounding stake.
AVERTISSEMENT: Les codes électriques locaux doivent toujours être
respectées lors de l'installation du piquet de mise à la terre.
The following diagrams illustrate the three service transformer secondary
connections most common in North America.
