IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that must be followed during installation of a ChargePoint® Networked Charging Station.
Grounding instructions
The ChargePoint® Charging Station must be connected to a grounded, metal, permanent wiring system; or an equipment-grounding conductor is
to be run with circuit conductors and connected to the equipment grounding terminal or lead on the Electric Vehicle Supply Equipment (EVSE).
Connections to the EVSE shall comply with all local codes and ordinances.
Safety and compliance
This document provides instructions to install the ChargePoint® Charging Station and should not be used for any other product. Before installing
the ChargePoint® Charging Station, you should review this manual carefully and consult with a licensed contractor, licensed electrician and

Introduction 1
This document provides step-by-step instructions on how to install a CT2023 ChargePoint® Charging
Station. As shown here, the CT2023 ships in five boxes:
Before installing stations
Before you begin installing a CT2023 charging station as described in this document, you must:
•ensure that the appropriate wiring, circuit protection, and metering is in place at the installation
location (see wiring diagram on page 1-3 of this document)
• ensure that the type of modem in each station you are installing is compatible with the type of modem
coverage available at the installation site (CDMA or GPRS)
• review the CT2023 Charging Stations Data Sheet (available at www.coulombtech.com/support/)
• review the mounting template (provided in this document and in the box containing the station’s body)
IMPORTANT: A PDF version of the mounting template is also available at
www.coulombtech.com/support/. When printing this version, print at 100% scale using 11” x 17”
paper and verify at least one dimension to ensure accuracy.
It is also recommended that you thoroughly review this document to familiarize yourself with the contents
of each shipping box, and the required installation steps.

Step 3 - Install channel struts
To mount the channel strut sections to
the concrete wall:
• Use the supplied wall mount
template to mark the location of
the four holes on the wall. Holes
must be 24” and 34” up from the
floor and be spaced exactly
21/2”apart.
•Using a Hammer drill and a 3/8”
masonry drill bit, drill four holes
21/2” deep.
• Install the four supplied
3/8” anchor bolts.
•Mount each channel strut to the
wall with the four 3/8” nuts and
large, thick washers supplied in the
shipping box (discard the washers
that came with the anchor bolts).
Tighten using a 3/8” drive rachet
with extension.
NOTES:
The bottom of the channel strut
should be located 20 1/2” above
the floor.
The two channel struts must be
plumb and parallel to each other.

Step 4 - Attach wall mount bracket
To install the wall mount bracket:
• Using the template as a guide to
determine their exact location,
install the four channel strut nuts
into the channel struts as shown.
•Mount the bracket to the channel
struts using the four supplied hex
head bolts and washers, as shown.
Tighten using the 3/8” drive and
9/16” socket.

Step 5 - Remove front panel
To remove the front panel:
•Using a T25 Torx driver, remove the
two captive screws in the filler
panel.
•Slide the filler panel upward to
remove.
•Remove the ground wire connector
from its tab located on the front
panel.
• Use the supplied allen wrench to
loosen the two screws that fasten
the panel to the body. These screws
are used for shipping only and can
be discarded.
•Slide the front panel upward to
remove.
Remove the two screws
that secure the front
panel to the body
Remove the
ground wire
from its tab
Loosen the two
screws on the
filler panel and
slide upwards to
remove
