Introduction
This document describes how to install an Express 250 DC fast charging station ins situations where the site
cannot pour a new concrete pad or run conductors underground. The Surface Conduit Entry (SCE) kit allows
surface drilling and epoxy installation of anchor bolts, as well as a rear conduit entry box for conductors to
enter the station through surface wireways. The SCE kit supports both Standalone and Paired installations.
The SCE kit also supports adding above-ground conduit to pair an already-installed Standalone station with
another Express 250 for shared DC output.
Installing an Express 250 using the SCE kit requires one ChargePoint Certified Installer and about 2.5 to 3
hours to complete (not including epoxy cure time). This time estimate includes the full charging station
installation, including the applicable steps described in the Express 250 Installation Guide. If this is a Paired
installation, allow an additional hour. This time estimate does not include the time needed to pull cables.
Note: This document is a supplement to the normal charging station installation described in the Express
250 Installation Guide that ships with the station. Ensure all installation instructions from that guide are
followed except where this guide deviates.
Note: Shunt trip wiring is normally a feature of the Express 250, but is not required for operation. If shunt
trip wiring will be used, run a wireway for the low voltage shunt trip wires that is separate from the AC
conductor wireway.
Before You Begin
Note: For assistance, go to chargepoint.com/support and find your region’s technical support number.
DANGER: RISK OF SHOCK. Before performing this procedure, follow standard practice and local
code to de-energize the circuit designated for each Express 250 at the service panel and lock
out/tag out the disconnect before proceeding. Use a multimeter to test that power is off. Keep
power off for this circuit until all cover panels are correctly reinstalled and the work scope is
completed. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY OR
LOSS OF LIFE.
Important: You must be a licensed electrician and complete an online training course to become a
ChargePoint certified installer, and to get a login for ChargePoint. If you do not complete this
training, you will be unable to complete the installation process. Go to: chargepoint.com/installers
or chargepoint.com/eu/installers
CAUTION: Do not use power tools during installation or servicing. Over-torquing can damage the
equipment.
CAUTION: Do not install the charging station in inclement weather. If you must complete the
installation in rain or wind, you must use a weather-proof shelter that covers all boxes and
components.

•Sheet metal drill with drill bits for wireway sizes listed above, as needed (pilot holes provided)
•Concrete drill, level feature recommended
•25 mm (1 in) and 6 mm (1/4 in) concrete bits
•25 mm (1 in) rebar bit if needed
•24 mm (15/16 in) open ended wrench
•Flathead screwdriver
•750 ml of epoxy with bonding strength of 11.7 MPa minimum, compressive strength of 82.7 MPa
minimum, and tensile strength of 49.3 MPa minimum, such as Hilti HIT-RE 500 V3 (normal cure time),
Hilti HY-200 (fast curing), or similar
Note: Different epoxy types have different cure times at various temperatures. Check local temperatures
for the site in advance to help choose an appropriate epoxy.
•Cable puller or fish tape
•Vacuum and/or brush
•Marker
•Isopropyl wipes
•Paper towels
Important: Read the Express 250 Charging Station Installation Guide, Express 250 Charging Station
Site Design Guide, and site drawings to source and bring the correct AC conductors (required),
shunt trip wiring (optional), DC conductors and lugs (Paired installations only), and Ethernet wiring
(Paired installations only).
Important: If the Express 250 will be paired, check the serial number on the rear surface just under
the cable swing arms. For North America stations with SNs prior to 1929xxxx, or EU/UK SNs prior
to 2003xxxx, the station also requires a Pairing Upgrade Kit. Contact ChargePoint for the kit and
the installation guide for that configuration.

Note: This product is compatible with the
Express 250 Adapter. If the station has a
slightly raised black or silver base below the
cover panels, as shown on this image, break
off the two front tabs on the SCE box base
along their scored edges.
Note: SCE installations require a larger rear
clearance than a normal Express 250
installation, to allow room for the SCE and
wireways. Wireways must enter the SCE on its
rear face. Conductor bend radius does not allow wireways to enter the SCE from its sides.
Check Site Readiness
Before beginning work, check that the site meets the basic requirements outlined below, as illustrated in the
following image. Measurements are listed in mm (in).
•The panel breaker serving the charging station matches the site drawing requirements depending on
local code and the type of installation: 62.5 kW Standalone, 125 kW Paired, or 50 kW de-rated (when
replacing a previous, lower-amperage system).
•The smooth, level concrete has been approved by a structural engineer for the Express 250 dimensions
and weight, OR conforms to these general specifications*:
•At least 305 mm (12 in) deep (or deep enough to be 305 mm (12 in) below the frost line)
•At least 1296 mm (51 in) on each side
•Contains #4 rebar top and bottom 305 mm (12 in) on center
•Concrete 2500 PSI minimum
* These pad specifications are applicable in most conditions, as described in the Express 250 Site Design
Guide. In some extreme conditions, a larger pad would be required.
•Charging station sites are positioned so that each station is centered on a parking space (unless
curbside), with the front of the station facing the vehicle. (This maximizes cable reach.)
•The cellular signal strength at the station location has been tested and is consistently strong. If RSRQ is
measured at -10 dB or better, then RSRP can be -90 dBm or better. If RSRQ cannot be measured or is
not adequate, RSRP must be -85 dBm or better.
•The service clearance of open space (not necessarily at system grade) extends a minimum of 610 mm
(24 in) beyond the station in front, 2156 mm (84.8 in) side to side centered on the station, and 305 mm
(12 in) above the station (image callout a, below). See the images below for rear clearance depending
on configuration.
•The front of the station has 352 mm (14 in) of space at grade from the front right anchor, extending
1700 mm (67 in) to the left, without any permanent obstructions (bollards, wheel stops, etc.) (image
callout b).

Express 250

If the conduit runs from the back of the SCE to the side(s), with rigid wireway elbows:
•The rear conduit clearance at grade is 700 mm (27.6 in)
•The recommended extra rear service clearance of open space (not necessarily at grade) is 300 mm
(12 in) for servicing the conduit, for a total of 1005 mm (39.6 in) from the front anchor
If the conduit runs from the back of the SCE straight back:
•The rear conduit clearance at grade is 550 mm (21.7 in)
•The recommended extra rear service clearance of open space (not necessarily at grade) is 300 mm
(12 in) for servicing the conduit, for a total of 855 mm (33.7 in) from the front anchor

Check the SCE Kit Contents
Check the contents of the SCE Kit before
beginning work. The SCE Kit might arrive
in multiple boxes. The full kit includes:
a. Surface mount plate
b. Box base
c. Box cover
d. Left and right side extrusions with
SCE cutouts (x2)
e. Fasteners:
•Box base screws (x8)

304.8 mm (12 in) long (x4)
•M16x13x2 hex nuts (x8)
•5/8 in ASTM F436 washers (x8)
Prepare the Express 250
Determine whether you are installing a new Express 250 station to be completely surface mounted, or you
are adding above-ground conduit to pair a Standalone station with another Express 250 for shared DC
output.
If you are installing a NEW station:
1. Receive the Express 250 station and its Power Modules at the site.
2. Follow the directions in section 1 of the Express 250 Charging Station Installation Guide to familiarize
yourself with the process, crate contents, and required tools and materials.
3. Begin installation with the next section, "Install Surface Mount Anchor Bolts" on page 9.
If you are UPDATING a station:
1. Receive the Express 250 Pairing Kit at the site.
2. Follow the directions in section 1 of the Express 250 Pairing Retrofit Guide to familiarize yourself with
the process, crate contents, and required tools and materials.
3. Power off the station and remove all cover panels as described in the Express 250 Pairing Retrofit Guide.
Note: Earlier stations had grounding straps on the Power Modules and their holders. If you are pairing an
existing station, you must replace these with the EMI shields included in your Pairing Kit. The straps are
not sufficient for paired stations.
4. Begin work in this guide with the section "Install the SCE Box Base and Box Cover" on page 11.

Install Surface Mount Anchor Bolts
1. Follow standard practice and local code to de-energize the applicable circuit and lock out/tag out the
disconnect before proceeding. Use a multimeter to test that power is off.
2. Place the surface mount plate at the proposed
location. Align the large left hole with AC conduit if
present (for example, when replacing an older
station). Check that the station placement on the pad
meets site requirements.
3. Use a marker to mark the locations for the Express
250 anchor bolts. Remove the surface mount plate.
4. Use the 6 mm (1/4 in) concrete drill bit to drill each
pilot hole about 51 mm (2 in) deep. The holes must
be parallel to each other and perpendicular to grade.
5. Use a vacuum or brush to clean the dust from the
holes.
6. Use the 25 mm (1 in) concrete drill bit to drill each
anchor hole a minimum of 229 mm (9 in) deep.
Anchor bolts must have 127 mm +/- 12.7 mm (5 in +/-
1/2 in) above grade.
7. Place the surface mount plate on the ground again.
Verify that the new holes for the Express 250 align
with the holes in the surface mount plate.
8. Thread a washer and a nut onto each anchor bolt, so that the measurement
from the top of the nut to the top of the bolt is 76 mm (3 in).
9. Put a piece of tape above each nut to prevent it from floating upward when
rotating the bolt into the epoxy later.
10. Prepare the epoxy. Ensure the applicator is dispensing correctly mixed epoxy
before beginning work (for example, the Hilti epoxy is white when unmixed
and grey when mixed).
Important: Ensure the rear clearance leaves
room for the conduit runs and for service
clearance.

11. Fill the first anchor bolt hole with epoxy until the
epoxy is about 44.5 mm (1.75 in) from the top of the
hole.
12. Insert the mounting bolt into the hole. Rotate the
mounting bolt as you insert it to draw epoxy into the
threads. Lift the anchor bolt again to see how close
to the surface the epoxy has filled. If the epoxy is
below grade level, add enough to fill the hole to
grade level. Use paper towels to wipe up any excess.
13. Measure the nut distance from the top of each bolt
again and adjust if needed. These nuts help secure
the surface mounting plate to the concrete and
should be flush against the base when installed.
14. If the Express 250 station will not be immediately
installed, insert a protective plastic cap over the bolt.
15. Use a level to check that each anchor bolt is plumb. If
needed, adjust while the epoxy is still setting.
16. Repeat the above epoxy steps for each of the other
three anchor bolts.
17. Stop. Allow the epoxy to cure for the initial cure time
listed on the epoxy, before beginning to install the
Express 250.
Note: If desired, use this time for measuring, cutting, and
fastening wireways to run conductors to the rear of the
station.
Important: Continue immediately to the next step
because the epoxy sets within about eight
minutes.

Express 250

Anchor and Label the Station
1. Check that the epoxy has set completely.
2. Torque all four nuts to 94.9 Nm (70 ft-lbs).
3. Follow the instructions in the Express 250 Installation Guide from the beginning of the guide to the end
of the section “Mount and Secure the Express 250”. The station should now be mounted on the anchor
bolts, leveled, and secured with the anchor washers and nuts.
4. Stop before connecting the AC wiring.
5. If required, adjust the ratings with a new label over
the existing ratings line, just below the swing arms
in the back:
a. If the Express 250 is being connected to wiring
and a breaker of 80 A, affix the 50 kW ratings label
to the station
b. If the Express 250 is being paired, affix the 125
kW label to the station
Install the SCE Box Base and Box Cover
1. Use a T25 Torx to remove the rodent guard L-brackets on
each side of the station, below the AC and DC wiring
terminals.
Important: The station should rest on the leveling nuts, not on the surface mount plate.

2. Install the rear EMI shield:
a. Position the rear EMI shield (a) over the closed Power
Module holder, the drain hose, and the cooling controller cover
(b). Ensure the cutout on the long edge is on the right side,
leaving the sensor wire clear.
b. Use a T20 Torx to remove the two screws (c) that align with
the top EMI shield tabs. Discard the star washers beneath
them, if present.
c. Use isopropyl wipes to clean the frame grounding locations
and both sides of the rear EMI shield tabs.
d. Use a T20 Torx to reinstall the top screws with an M5 flat
washer from the installation kit to secure the top tabs of the
shield on each side.
e. Use a T25 Torx, an M5 screw, and an M5 washer to attach the
rear EMI shield to each middle and bottom grounding location
on the rear of the frame (d). Torque to 4 Nm (35 in-lbs).
3. Loosen the captive screws along the bottom edges
of the SCE to release the cover from the base. Set the
cover aside.
4. Based on the provided pilot holes, use a sheet metal
drill bit to create the circle in the rear face of the box
base for AC (e). Drill out the circle for DC only if the
station will be paired (f).
5. If the station will have shunt trip wiring (g) or
Ethernet (h), use a 45 mm (12/16 in) core bit to drill
the hole(s) based on the provided pilot holes.
CAUTION: If the top edge of the EMI shield risks contact
with the wiring below the cooling controller or the drain
hose, pad the edge of the shield with electrical or duct
tape to prevent abrasion.
Important: Ensure the locations of the shunt trip and Ethernet holes do not interfere with routing
wireway elbows and conduit. Calculate height clearance for all wireways.
