EV40 User’s Manual
Caution:
If a 240V 3-phase feed is from a Delta-connected secondary, the leg used
must have a center-tap. That tap must be Grounded. Only the two phases either side
of the center-tapped leg can be used. See Fig. 4 below.
Attention:
Si une alimentation triphasés 240V provient d'un triangle connecté
secondaire, la bornes utilisée doit avoir une centre-tap. Que la tap doit être Mise à la
Terre. Seuls les deux phases l’une ou de l’autre côté du centre tapped brancher peut
être utilisés. Voir la Figure. 4 ci-dessous.
Caution: Warranty is void if this unit is wired improperly
Attention: La garantie est annulée si cette unité n’est pas correctement câblé
Warning:
Only a qualified electrician should perform the installation. The
installation must be performed in accordance with all local electrical codes and
ordinances.
Avertissement:
Seul un électricien qualifié doit effectuer l'installation. L'installation
doit être effectuée conformité 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 transformer outputs
correspond to the same inputs on the EV40 Charger. 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 EV40 Charger. 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 protection 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 service, 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.
