OPTIONAL FEATURES
Overview
The HCS Series EVSE can be built with additional functionality
including abilities for access control, shared circuit power, and
load management.
These features can often be used together, but must be built
to order. Reference the chart below to verify which combination
of HCS expanded functionalities would best suit specic
requirements.
Contact a Customer Service Representative at [phone] for
additional information. Installation instructions for each expanded
functionality follow.

NOTE: Each HCS delivered with Optional Features
that use Control Wires (see Table 3) comes with 3 feet
(1 m) of conduit containing the communication wires.
When using Share2, HCS stations can be placed up 100
feet (30.5 m) apart. ClipperCreek utilizes 24 AWG
(American Wire Gauge) Belden cable for the
communication harness. Other 24 AWG cabling is
acceptable. The 8 Wire Harness uses Belden cable #9538;
the 10 Wire Harness uses Belden cable #9540; and the 15
Wire Harness uses Belden cable #9541.

ChargeGuard Enabled HCS
ChargeGuard is a built-in key based access control option. Refer to
these instructions to operate a ChargeGuard enabled HCS EVSE.
1. Connect the HCS EVSE to the vehicle with the
SAE J1772 connector.
2. To enable charging:
a) Insert the key into the switch located on the right side
of the HCS EVSE.
b) Turn the key 90° clockwise to the vertical position as
shown in the Figure 1.
c) The “CHARGING” LED light will illuminate green on
the front panel, indicating the vehicle is now being
charged.
3. To allow charging of Multiple Vehicles:
a) Leave the key in the present vertical position.
This allows disconnection of the EVSE from one
vehicle and reconnection to the same or another vehicle
without moving the key.
b) The EVSE will be enabled and power will be available
to vehicles as long as the key remains in the vertical
position.

NOTE: The key cannot be removed in the vertical
position. See Step 4 for key removal instructions.
4. To restrict access:
a) Turn the key counterclockwise 90° as shown in
Figure 2.
b) Remove the key.
c) If a vehicle is connected and charging, that vehicle will
continue to charge as long it remains connected to the
EVSE.
d) Once the vehicle is disconnected from the EVSE, the
EVSE will require the key to activate another charging
session.
Figure 2: ChargeGuard OFF or Restricted Access Position:
The EVSE will be enabled for as long as the vehicle remains
plugged in. The EVSE will reset when the vehicle connector is
unplugged.

Replacement Keys
Should replacement keys be required, contact the ClipperCreek
ofce at [phone]. Please have the EVSE serial number
available for reference.
NOTE: If the Share2 option is desired to work in
conjunction with the ChargeGuard option, these two
options must be ordered and built at the same time
(Share2 and ChargeGuard are factory-installed options
and cannot be installed in the eld). The optional Share2
feature allows two EVSE to share power supplied by one
circuit breaker. Please refer to the Share2 Enabled HCS
section of this User Manual for further instructions.

ChargeGuard EX Enabled HCS
ChargeGuard EX provides a simple interface to connect the
ClipperCreek HCS EVSE to an existing building access control
or other third party access control system. With ChargeGuard EX
a momentary contact closure driven by successful authentication
in an access control system can activate the HCS ChargeGuard
EX enabled station for a single charging session. Alternatively,
maintaining the contact closure will leave the station enabled for
multiple charging sessions until the connection is released.
When the Orange and Yellow control wires are shorted together,
the EVSE is “ON” and ready to charge a vehicle. When the
wires are disconnected, the station is “OFF” and requires a valid
activation through the access control system in order to begin
charging again. Refer to Figure 3 and Figure 4.
ChargeGuard EX can be utilized in two ways:
1. If individual access control is desired (for each charge
session), the access control system will need to provide
a momentary short to the Orange and Yellow wires
which will activate the station for a single charge
session. In this implementation once the vehicle is
disconnected the station will require a successful
authorization through the access control system.
2. If open access is desired, connect the Orange and
Yellow wires for as long as open access is desired.
As long as the Orange and Yellow wires are shorted
together, the station will be enabled for use.

1. Connect the HCS EVSE to the vehicle with the SAE
J1772 connector.
2. Enable charging by using access control.
3. The “CHARGING” LED light will illuminate green on
the front panel, indicating the vehicle is now being
charged.

Share2 Enabled HCS
Share2 allows two EVSE to share power supplied by one
circuit breaker. When only one EVSE is charging a vehicle,
the full charging capacity is available to that vehicle. When both
EVSE are charging vehicles, each EVSE will offer 50% of the
circuit capacity to each vehicle (thus “sharing” the circuit breaker).
The Share2 EVSE will have either a 15, 8 or 10 wire harness.
Please refer to the Wiring Instructions for either the 15, 8 or 10
wires dependent on the particular harness congurations. These
harnesses have different color wires so it is important to follow
the correct instructions per 15, 8 or 10 wire counts.
CAUTION: DO NOT STRIP WIRES THAT ARE
UNUSED.
ATTENTION: NE PAS DÉPOUILLER LES FILS
INUTILISÉS.

Share2 Wiring Instructions: 15 Wire Harness
Follow the Wiring Diagram in Figure 5 for proper wiring of a
Share2 that utilizes a 15 wire harness. Wiring connections can
be made in a junction box or pedestal body. Strip the Orange/
BK, Orange, and White/BK wires ONLY. Use wire nuts (not
included) to secure the Orange/BK and Orange wires to the
opposing White/BK wire as indicated by the black dots in
Figure 5.
NOTE: Wires with black dotted markings are referenced
with "/BK" and wires with white dotted markings are
referenced with "/WH."

After wiring is complete use a DC volt meter to test functionality.
Connect the volt meter negative lead to ground, then connect the
volt meter positive lead to the White/BK wire. A measurement
greater than 4V DC should be seen when a vehicle is not connected
or not charging. A voltage less than 1V DC will be measured on the
White/BK wire when a vehicle is charging.
NOTE: There is a 5 second delay once one vehicle stops
charging before the White/BK wire returns to greater than
4V DC and an additional 10 seconds before full circuit
power will be available to the other vehicle.

can be made in a junction box or pedestal body. Strip the Blue,
Brown and White wires ONLY. Use wire nuts (not included) to
secure the Blue and Brown wires to the opposing White wire as
indicated by the black dots in Figure 6.

COSMOS Load Management Enabled HCS
The COSMOS option is a Load Management Access Point which
can be connected to a third party load management monitoring and
control system to verify energy usage, optimize energy efciency,
and promote energy conservation.
The COSMOS Load Management Enabled HCS provides two
ways to control energy usage:
1. The Digital Interface
2. The Serial Interface (if the Serial Interface is used it
will take precedence over the Digital Interface)
The COSMOS enabled EVSE will have either a 15, 8 or 10 wire
harness. Please refer to the Wiring Instructions for either the 15 or
8 and 10 wires dependent on the particular harness congurations.
These harnesses have different color wires so it is important to
follow the correct instructions per 15 or 8 and 10 wire counts.
