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.

FCC Compliance Statement

This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the manufacturer’s
instruction manual, may cause harmful interference with radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case, you will be required to correct the interference at your own expense.

Important: Changes or modifications to this product not authorized by Coulomb Technologies, Inc., could affect the EMC compliance and revoke
your authority to operate this product.

Exposure to Radio Frequency Energy: The radiated power output of the 802.15.4 radio and cellular modem (optional) in this device is below the
FCC radio frequency exposure limits for uncontrolled equipment. This device should be operated with a minimum distance of at least 20 cm
between the 802.15.4 and cellular antennas and a person’s body and must not be co-located or operated with any other antenna or transmitter
by the manufacturer, subject to the conditions of the FCC Grant.

Before installing stations

The instructions provided in this guide assume that the appropriate wiring, circuit protection, and
metering is in place at the installation location. Before you install, you must also 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 (GPRS or CDMA).

To assist in the process of preparing the installation site, thoroughly review the following documents:

• Wiring diagrams (see page 1-3 of this document)

• CT2021 Charging Stations Data Sheet (available at www.coulombtech.com by clicking the “Products”
link, then the “Library” link)

• Mounting template (provided in this document and in the box containing the station’s body)

IMPORTANT: If you are printing the PDF version of the Mounting Template, be sure to print at full

scale using 11” x 17” paper. Verify at least one dimension before using a self-printed template.

NOTE: Prepare the site according to the instructions provided on page 2-5 of this document.

It is also recommended that before you begin installing the CT2021 charging station, you thoroughly
review the contents of this document to familiarize yourself with the contents of each box and the
required installation steps.

below the
concrete

Install J-Bolts and conduit into concrete
as illustrated. Use the supplied base
plate template to ensure correct
alignment.

IMPORTANT!

•The concrete block should measure

24” (61 cm) x 24” (61 cm) x
36” (91 cm) deep. Check local
codes to ensure compliance.

• The J-Bolts must extend at least

2

½” (6.4 cm) above the concrete

and 9” (23 cm) below the concrete.

• The conduit must extend 12” to 24”

(30 to 61 cm) above the concrete,
