Instructions Pertaining to a Risk of Fire or Electric Shock
followed:
• Use this EVSE to charge electric vehicles equipped with an
SAE J1772 charge port only. Consult the vehicle’s owner
manual to determine if the vehicle is equipped with the
correct charge port.
• Make certain the EVSE SAE J1772 charge cable is
positioned so it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
• This product contains no user serviceable parts. Consult
the Customer Support section in this manual for service
information. Do not attempt to repair or service the EVSE
yourself.
• Do not operate your EVSE if it or the SAE J1772 charge
cable is physically open, cracked, frayed, or otherwise
visibly damaged. Contact a Service Representative for
service immediately. Consult the Customer Support
section in this manual for information on the Service
Representative in your area.
• Not for use in commercial garages where a
SAE J1772 charge cable.
• Do not allow children to operate this device. Adult
supervision is mandatory when children are in proximity to
an EVSE that is in use.

WARNING:
at the circuit breaker panel prior to plugging into or
unplugging from a wall socket.
NOTE: VENTILATION - Some electric vehicles require
an external ventilation system to prevent the accumulation
of hazardous or explosive gases when charging indoors.
Consult the vehicle owner’s manual to determine if your
vehicle requires ventilation during indoor charging.
NOTE: Vehicles which conform to the SAE J1772
standard for communication can inform the charge
station that they require an exhaust fan. The HCS is not
equipped to control ventilation fans. Do not charge the
vehicle with the HCS if ventilation is required.
CAUTION: DO NOT CHARGE a vehicle indoors if it
requires ventilation. Contact a Service Representative for
information.
Save these instructions for future reference.

OPERATION
NOTE:
discussed in this manual; we recommend contacting
Enphase, Inc., as some units are not yet available.
The HCS-D EVSE is a compact wall or pedestal-mounted EVSE
that provides the Plug-in Hybrid or Battery Electric Vehicle
manageable link between the power grid and the PEV.
Simply unwrap the SAE J1772 charge cable and plug the connector
the EVSE makes 100% of its power available to that vehicle.
vehicle completes its charge, the other vehicle has access to 100%
of the power until it completes charging, is unplugged, or another
vehicle that requests power is connected to the HCS-D. The status
of each connected vehicle is displayed on the front panel of the
HCS-D.
Normally, the vehicle will immediately request a charge once the
charging cycle will begin. 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.

all three phases of a 3-phase feed! You may use any two
phases of a three phase wye-transformer feed. The

connection is not required by the HCS-D. Only Line 1, Line
2, and Ground are required, as shown in Figure 3.
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 4.

WARNING
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 known, and the
3 wires from the main circuit breaker panel are connected and
labeled correctly. Figures 2, 3, and 4show 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 HCS-D.
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 HCS-D. 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
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.
The following diagrams illustrate the three service transformer
secondary connections most common in North America.

MOUNTING PROCEDURES
Locate the wall mounting location for the EVSE:
• On the hardwired HCS-D, the three service conductors are
unit. The HCS-D must be positioned such that this conduit
can reach a nearby junction box.
• On the plug-in HCS-D, the NEMA plug head is connected
bottom side of the HCS-D. The plug-in HCS-D must be
positioned such that this plug can safely be inserted into a
wall-mounted NEMA socket. Do not allow the power supply
• Position the bottom of the EVSE at a comfortable height and
front panel indicators of the EVSE can clearly be seen by
the user of the device.
• The HCS-D has two vertically aligned mounting holes
Use a ruler or template to mark hole locations on the
mounting surface.
WARNING:

HCS-D EVSE Mounting for Hollow-Wall Construction
• Place the unit such that both mounting holes can take
advantage of solid structural framing inside of the wall or a
strong wall surface such as plywood.
•

pilot holes to allow the lag screw to grip the wooden structure
while preventing the wood from cracking or splintering while
the screw is fastened.
• The included plastic angle washers can be oriented to allow
the lag screws to be fastened at an angle while still providing a
•
plastic angle washer and the head of the lag screw.
• If either mounting hole does not have a solid mounting
