•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)
• prepare the installation site according to the instructions provided in Appendix A of this document
• review the CT2025 Charging Stations Data Sheet (available at www.coulombtech.com/library.php)
• 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/library. When printing this version, print at 100% scale using 11” x 17” paper
and verify at least one dimension to ensure accuracy.

Installing the Bollard Mount 2
Before you start
Before installing a CT2025 ChargePoint® Charging Station, prepare the installation site as described in
Appendix A of this document.
After the installation site has been prepared, you will need the following tools, in addition to contents in
the bollard mount and top assembly shipping boxes, to install the bollard mount:
• Torx Driver T25 - Tamper-Resistant. This driver is available at www.wihatools.com (Item 36281) and
www.mcmaster.com (Item 83335A64).
•#2 Phillips screwdriver
•#2 Slotted screwdriver
•Level
NOTE: Due to the length of the bollard mount, it is recommended that two people participate in the
installation, particularly for Step 7.
Overview of steps
Installing the CT2025 ChargePoint® Charging Station’s body assembly involves a few simple steps:
1. Check boxes for correct contents (see page 2-2)
2. Remove mounting pole/base plate from body assembly (see page 2-4)
3. Remove access panel (see page 2-5)
4. Install top assembly (see page 2-6)
5. Mount base plate/pole assembly (see page 2-10)
6. Install body (see page 2-11)
7. Re move f il le r p an el a nd f as ten b ot tom f ront p an el (see page 2-13)
8. Connect wires to wiring terminals (see page 2-14)
These steps are detailed in the remainder of this chapter. When you have completed these steps, you will
be ready to install the holsters and cable assemblies as described in Chapter 3.

Top assembly
The top assembly ships in a box
containing:
• Pre-assembled top assembly
CAUTION: DO NOT remove the
dowel pins that are attached to the
top assembly’s cables. It is
important that these pins stay in
place until after the cable
retractors have been fully installed
(see Chapter 5).
•Light bulb
• Light bulb cover
• Cable clamp sections (4)
•Screws for cable clamps (10)
NOTE: Only gateway stations have three
cables. Therefore, the top assembly
may not be exactly as illustrated here.

Step 2 - Remove mounting pole/base plate from body assem-
bly
TIP ! It is easier to complete this step if the bollard mount is laying down in a horizontal position, held in
place by its original packaging material as shown.
To remove the mounting pole/base plate from the body assembly:
• Using a Philips screwdriver, loosen the two screws on each front bracket
.
•Remove the front brackets
• Slide the mounting pole/base plate towards the left to allow the base plate to clear the body
assembly, then pull it upwards to remove it from the body assembly.
Loosen these four screws

Step 3 - Remove access panel
TIP ! It is easier to complete this step if the bollard mount is laying down in a horizontal position, held in
place by its original packaging material as shown.
To remove the access panel:
• Remove the access panel’s front cover by pulling the yellow tab (located on the access panel’s front
cover) towards you.
• Using a T25 Torx Driver, turn the four screws on the access panel counter-clockwise to loosen, as
shown.
•Pull the access panel towards you to remove.
Pull yellow tab towards you
Loosen the
four screws

Step 4 - Install top assembly
Before installing the top assembly, install the
bulb and cover:
•Screw the bulb into the socket.
• Position the cover over the light bulb as shown.
• Using a T25 Torx driver, tighten the two captive screws to
secure the cover to the top assembly.
To install the top assembly:
TIP ! It is easier to install the top assembly if the bollard mount is
laying down in a horizontal position, held in place by its original
packaging material.
• Using the supplied Allen wrench, remove the two set screws on the top front panel.
• Slide the top front panel down, far enough so you can access the upper tie wrap anchor, located at the
top of the body assembly.
• Using a Philips screwdriver, loosen the three screws located at the top of the body assembly.
Loosen the set
screw on each
side

•Slide the foam packaging upwards so it fully supports the top of the body assembly. Then position the
top assembly onto the top of the body assembly, ensuring that the top assembly’s wiring runs along
the inside of the body. You may find it helpful to use foam packaging to support the top assembly.
CAUTION: DO NOT remove the dowel pins that are attached to the top assembly’s cables. It is
important that these pins stay in place until after the cable retractors have been fully installed (see
Chapter 5).
•Align the three brackets on the top assembly with the corresponding screws on the body assembly, as
shown.
•Hold the top assembly against the top of the body assembly to ensure there is no gap between the top
assembly and the body. Using a Philips screwdriver, maintain a compressive force on the top assembly
while tightening the three screws to 12 inch-lbs—first tighten the left screw, then the middle screw
(back), and then the right screw.
Ensure the top assembly’s wiring runs
along the inside of the body
Slide the foam packaging
upwards (as shown here) to
allow it to fully support the top
of the body assembly
Align all three
brackets

• Use the pre-installed tie wrap to secure the top assembly’s wiring.
•Slide the front panel upwards as far as it can go.
NOTE: To prevent water ingress, the bottom edge of the top front panel must be aligned with the
features cut into the main body.
•Using the supplied allen wrench, tighten the two set screws on the front panel to 12 inch-lbs.
WARNING! You must tighten these set screws before continuing—failure to do so could result in
injury.

Step 5 - Mount base plate/pole assembly
To mount the base plate/pole
assembly:
• Pull all three wires up through the
conduit and the mounting pole.
•Place the base plate/mounting
pole assembly over the wiring
conduit and attach the base plate
to the J-Bolts using the
installer-supplied nuts and washers
as shown.
• Adjust the nuts as necessary to
ensure the base plate and
mounting pole is plumb.
•When plumb, tighten the nuts
securely.
IMPORTANT: Ensure the base
plate/pole assembly is COMPLETELY
level by adjusting the nuts underneath
the base plate. Verify accuracy after
each adjustment by positioning the
level at various locations on the pole
and above each bolt. The base plate
should be level within .25º of 100%
accuracy.
Adjust these nuts as
necessary to ensure
the mounting pole is
plumb
Position a level
at various
locations,
including above
each bolt, to
ensure the
base plate is
level within .25º
of 100%
accuracy

Step 6 - Install body
NOTE: Due to the length of the
bollard mount, it is recommended
that two people participate in this
step.
To install the body:
• Ensure the two front brackets
are within reach of the base
plate so they are ready to be
installed.
• Position the body assembly
over the mounting plate in a
diagonal position, as shown, to
align the slots on the body
assembly with the grooves on
the base plate.
•When the correct alignment
has been achieved, lift the top
of the body assembly upwards
to its vertical position.
Align the body
with the base
plate

ChargePoint® Charging Stations
2-12
Step 6 - cont’d
•Install brackets to stabilize the
bollard. To do so, loosely
secure the body to the
mounting pole by aligning the
top front bracket with its
corresponding back bracket
and tightening its two screws
with a Philips screwdriver.
Repeat for the bottom front
bracket.
•While ensuring the body is
level, tighten all four screws on
the front brackets using a
Philips screwdriver.
IMPORTANT: Ensure the
body is firmly aligned to the bottom
surface and that no movement
(rocking) can take place, even
when significant pressure is
applied.
