OPERATION
The ZEFNET Pro EVSE is a floor mounted commercial EVSE that provides
the Plug-in Hybrid or Battery Electric Vehicle (together Plug-In Electric
Vehicles, or “PEV”) user with a safe and manageable link between the
power grid and the PEV.
Simply unplug the SAE J1772 charge plug from the ZEFNET Pro holster,
and plug firmly into the vehicle’s charge port.
Normally, the vehicle will immediately request a charge using a special
communication line in the cable. Within a few seconds the LED indicators
at the top of the unit will transition from Blue, and then to Orange and the
charging cycle will begin (depending upon the specific vehicle - some
vehicles go straight to Orange to indicate charging). After an average
driving day the vehicle battery pack will require several hours to recharge
completely. Charging overnight is the most convenient way to maintain
healthy batteries and ensure the vehicle’s full range will be available for the
next day.
When the vehicle has stopped charging the Orange LEDs on the ZEFNET
Pro will change to Green. To remove the connector head once a charge
cycle has completed (or to interrupt a charge in progress) press and hold
down the latch release lever on the connector handle then unplug the
connector from the vehicle charge port.

INSTALLATION - SERVICE CONNECTIONS
CAUTION: To reduce the risk of fire, connect only to a circuit
provided with the appropriate maximum branch circuit
overcurrent protection in accordance with the National Electrical
Code, ANSI/NFPA 70 (US) or the Canadian Electric Code C22.2
NO. 280-13 (Canada).

Load balancing refers to ZEFNET software settings that allow the ZEFNET
Pro to share a single circuit entering the unit, instead of the standard two
dedicated circuits the ZEFNET Pro typically requires.
CAUTION: This is a single-phase device. Do not connect all
three phases of a 3-phase feed! You may use any two phases
of a three phase wye-transformer feed. The centerpoint of the
three phases (usually used as Neutral) must be grounded
somewhere in the system. A Neutral connection is not required
by the ZEFNET Pro. Only Line 1, Line 2, and Ground are
required, as shown in Figure 3.

ZEFNET Pro User Manual
12
CAUTION: The two phases used must each measure 120V
to Neutral. Earth Ground must be connected to Neutral at
only one point, usually at the service entry breaker panel.
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 on either side of the center-
tapped leg can be used. See Figure 5.
CAUTION: Warranty is void if this unit is not wired properly.
WARNING: Only a qualified electrician should perform the
installation. The installation must be performed in accordance
with all local electrical codes and ordinances.
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
3, 4, and 5 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 ZEFNET Pro.
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
ZEFNET Pro. 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

ZEFNET Pro User Manual
13
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.
The following diagrams illustrate the three service transformer secondary
connections most common in North America.
Figure 3: 220/240V Single Phase
Figure 4: 208V 3-Phase, Wye-Connected

ZEFNET Pro User Manual
14
NOTE: With a wye-connected secondary, any two of the legs can
be used to provide 208V to the ZEFNET Pro. For example, L1 &
L2, or L1 & L3, or L2 & L3. Leave the unused leg open. Do not
connect it to a Neutral bar, or to Ground. Be sure the center point
is grounded to Earth somewhere in the system.

ZEFNET Pro User Manual
15
Figure 5: 240V 3-Phase, Delta-Connected, with Center-Tap on One Leg
CAUTION: With the delta connection, one leg must be center-
tapped. Only the two phases on either side of the center tap can
be used. The two phases must both measure 120V to Neutral.
The third line (L3) of the delta is 208V, with respect to Neutral,
and is sometimes referred to as a “stinger” or “wild leg”. Do not
use this third line! Consult the transformer manufacturer’s
literature to be sure the single leg can supply the required power.
CAUTION: A 3-phase delta-connected transformer secondary
without a center-tap on one leg cannot be used with the ZEFNET
Pro. No “Neutral” point is available to be connected to ground for
ground-fault protection. The ZEFNET Pro will not allow the

ZEFNET Pro User Manual
16
contactor to close if it does not sense the presence of a Ground
wire connected to a “Neutral” point on the transformer secondary.
