CAUTION: To reduce the risk of fire, connect only to a circuit provid-
edwith 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).
ATTENTION: Pour réduire le risque d’incendie, de se connecter
uniquement à un circuit fourni avec le approprié circuit de dérivation
protection maximale contre les surintensités, en conformité avec le Code
National électrique ANSI/NFPA 70 (US) ou Code Canadien de l’électric-
ité C22.2 NO. 280-13 (Canada).
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 center-point of the three phases
(usually used as Neutral) must be grounded somewhere in the system. A
Neutral connection is not required by the HCS. Only Line 1, Line 2, and
Ground are required, as shown in Figure 3 on page 11.
ATTENTION: Il s’agit d’un appareil monophasé. Ne pas relier tous
les trois phases d’une alimentation triphasée!!! Vous pouvez utiliser
les deux phases d’un triphasé en étoile transformateur alimentation. Le
point central des triphasé (généralement utilisé comme Neutre) doit être
Mis à la Terre quelque part dans le système. Une connexion Neutre n’est
pas exigée par la HCS. Seulement ligne 1, ligne 2, et Mise à la Terre sont
nécessaires, comme le montre la Figure 3 à la page 11.
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.
ATTENTION: Les deux phases utilisées doivent mesurer chaque 120V
à Neutre. Mise à la Terre doit être connecté au Neutre en un seul point,
généralement à l’entrée panneau de disjoncteurs de service.

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 on the
following pages 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 HCS. 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. 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
service, a grounding stake must be driven into the Earth 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.

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”. Do not use this third line! Consult the transformer
manufacturer’s literature to be sure the single leg can supply the
required power.
ATTENTION: Avec la connexion triangle, une borne doit être centre-
tapped, et seulement les deux phases d’un côté ou de l’autre du centre
tap peut être utilisé. Les deux phases doivent mesurer 120V à Neutre.

MOUNTING PROCEDURES
Locate the wall mounting position of the EVSE:
• On the hardwired HCS, the three service conductors are shielded by three
feet of flexible conduit. The HCS must be positioned such that this conduit
can reach a nearby junction box.
• On the plug-in HCS-P, the NEMA plug head is connected by one foot
of cable (including the plug head) to the bottom side of the HCS-P. The
HCS-P must be positioned such that this plug can safely be inserted into a
wall-mounted NEMA socket.
• The plug-in HCS-P is intended for indoor use only. Currently, NEMA 14-50
and 6-50 plugs and receptacles are not outdoor rated.
• Position the bottom of the charge station at a comfortable height and at least
18 inches above the ground for indoor installations and 24” off the ground
for outdoor installations. Ensure that the LEDs on the front panel of the
EVSE can clearly be seen by anyone who will be operating the device.
• The HCS has two vertically aligned mounting holes spaced 17” apart, one
each on the enclosure top and bottom. Use a ruler or template to mark hole
locations on the mounting surface.
WARNING: For safety, always turn off input power to the charge
station at the circuit breaker panel prior to plugging it in or wiring
it to the service lines. Likewise, turn off the circuit breaker prior to
unplugging it or disconnecting the unit from the service lines.
AVERTISSEMENT: Pour sécurité, toujours désactiver le courant
d’entrée de la station de recharge au niveau du disjoncteur du panneau
avant de le brancher ou de câblage à les lignes de service. De même,
coupez le disjoncteur avant de le débrancher ou déconnecter l’unité à
partir des lignes de services.
CAUTION: A 3-phase delta-connected transformer secondary without
a center-tap on one leg cannot be used with the HCS. No “Neutral”
point is available to be connected to ground for ground-fault protection.
The HCS will not allow the contactor to close if it does not sense the
presence of a Ground wire connected to a “Neutral” point on the
transformer secondary.
ATTENTION: Un triphasé triangle-connecté transformateur
secondaire sans centre-tap sur le terminal ne peut pas être utilisé
avec la HCS. Aucun point “Neutre” est disponible pour être connecté
à Mise à la Terre pour protection de défaut à la terre. Le HCS ne
permettra pas le contacteur de fermer si elle ne détecte pas la présence
d’un fil de Masse connecté à un point “Neutre” sur le secondaire du
transformateur.

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 ply-
wood.
• Size ¼-20 lag screws are recommended for mounting the HCS to a wooden
structure. Pre-drill appropriately sized 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 solid flat backing to the
screw head.
• If the screw head is smaller than the 3/8” washer aperture, an additional flat
washer will need to be placed between the plastic angle washer and the head
of the lag screw.
• If either mounting hole does not have a solid mounting structure (such as
drywall without a solid backing) it will be necessary to use proper anchor-
ing hardware such as drywall toggles or molly bolts.

FOR SOLID-WALL CONSTRUCTION
• To secure the unit in concrete, pre-drill appropriately sized holes and use
multi-set or wedge anchor hardware at both mounting points.
• To secure the unit in brick or stone, pre-drill appropriately sized holes and
use sleeve anchors at both mounting points.
• The included plastic angle washers can be oriented to allow bolts to be
fastened either at an angle or perpendicular to the mounting surface. Note
there are two different sets of plastic angle washers included. Select those
washers that best accomodate the mounting hardware “angle of attack” and
orient them accordingly.
• Note that if the head of the mounting hardware is smaller than the 3/8”
plastic angle washer aperture, an additional flat washer will need to be
placed between the plastic angle washer and the mounting hardware.
• Machine screw size ¼-20 hardware is recommended for mounting the
HCS. Screw shafts of at least 2” are recommended. The HCS plastic angle
washer hole size is 3/8” in diameter, so ensure that the screw heads are of a
larger diameter. Place appropriately sized washers between the screw heads
and the HCS enclosure mounting flanges.

WIRING INSTRUCTIONS
(Hardwired HCS)
Route the HCS conduit to a nearby junction box. Use the included ½” trade size
watertight conduit fitting and sealing washer to provide a moisture-resistant seal
between the conduit fitting and the junction box. If necessary, drill a 7/8”diame-
ter hole to accommodate the conduit fitting. For outdoor installations ensure the
junction box is fully sealed using appropriate electrical grade silicone sealant.
Before connecting the HCS service conductors, please carefully read the section
of this manual titled Service Connections on page 9. If you are unsure of the
type of power provided at the service panel, please consult with your local utility
or call your Service Representative for assistance.

RECEPTACLE INSTRUCTIONS
(Plug-In HCS-P)
The HCS-P is fitted with either a NEMA 14-50P or 6-50P plug extending from
the bottom of the HCS enclosure. Regulations limit this plug to a maximum of
12 inches in length, including the plug head. For this reason, the HCS-P must be
mounted above the NEMA receptacle and must also be located within 12 inches
of it.
In both NEMA 14-50P and 6-50P configurations, the ground pin is located at the
furthest point on the plug. With this in mind, it is recommended that a NEMA
14-50R or 6-50R receptacle be oriented accordingly, such that the ground socket
is at the lowest point.
