ChargeGuardTM EX HCS INSTRUCTIONS

ChargeGuardTM 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 ChargeGuardTM EX
a momentary contact closure driven by successful authentication
in an access control system can activate the HCS ChargeGuardTM
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.

ChargeGuardTM 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.
