1Site Design Guidelines 1
This document describes how to design an installation site for the ChargePoint® Express 280 DC fast
charging station and install the Concrete Mounting Template, before station installation. An Express 280
station can be installed to operate by itself (called “Standalone”) or to share power with one other Express
280 station for higher throughput (called “Paired”).
IMPORTANT: You must be a licensed electrician and complete online training to become a
ChargePoint certified installer. If you do not complete training, you cannot access the
ChargePoint network to complete installation.
Find online training at: chargepoint.com/installers
If the charging station is not installed by a ChargePoint certified installer, using a ChargePoint
approved method, it is not covered under warranty and ChargePoint is not responsible for any
malfunctions.

CAUTION: Use low torque settings when working with power tools during installation or
servicing. Over-torquing can damage the equipment.
WARNING: Do not install or service the charging station in inclement weather. If you work in rain
or wind, you must use a weather-proof shelter that covers all boxes and components.
Note: For all charging station specifications other than dimensions and weights, refer to the product's
Datasheet found online at chargepoint.com/guides.
For assistance, go to chargepoint.com/support and find your region’s technical support number.
Installing an Express 280 requires two people and takes approximately 3-4 hours. This time estimate does
not include the time needed to pull DC and Ethernet cable for a Paired installation if it is not already done.
Paired installation also requires contacting a ChargePoint support technician to perform any required
software updates and configuration.
IMPORTANT: Ensure the installation complies with all applicable codes and ordinances.
Pairing Two Express 280s
The Express 280 can be installed either as a standalone system, or paired with another Express 280 using a
DC connection to more flexibly share load. The two Power Modules in the base of each charging station can
be shared in any combination according to charging need. This allows high power output in sites with
space constraints.
To pair two charging stations, all of the following are required:
lAdditional conduit or ducting correctly installed between the two charging stations for DC
conductors and Ethernet wiring
lBoth stations must be provisioned for full power back to the panel (not allowed on “power select”
stations)
Initial Site Guidelines
An onsite evaluation is needed to determine conduit and wiring requirements from the panel to the
proposed parking spaces, as well as to measure cellular signal levels and identify suitable locations for any
necessary cellular signal booster equipment.
2
Pairing Two Express 280s

If you have pre-existing infrastructure or are using your own preferred electrical contractor to prepare your
site, you must complete a Construction Signoff Form to certify compliance with electrical specification
requirements and to ensure everything was prepared to ChargePoint specifications.
IMPORTANT: Always check local codes or consult an engineer to ensure the site is prepared in
compliance with all applicable regulations. Local authorities might not allow a unit to operate if it
is not installed to code.
Plan for Future Charging Capacity
ChargePoint recommends planning to install charging stations for 5-10% of parking spaces, or 10-15% for
high electric vehicle (EV) adoption areas like California. Designing electrical infrastructure to support
current and future needs for EV charging helps avoid costly modifications later as demand for EV charging
grows.
Consider these methods to prepare a site for future charging stations in a later phase of work:
lAdd extra capacity if electrical panels are being upgraded now
lUse sub-panels as a way to shorten electrical paths
lOversize the conduit between the main electrical panel and future stations
lInstall pull or junction boxes at the end of an existing row of charging stations, to ease cable pulls for
future stations
lIf a junction box or disconnect will be installed between rows of stations, oversize the wiring
between the main panel and the junction box to prevent needing to re-pull wire later
Charging Station Placement
To help minimize costs, choose station locations that are as close as possible to the available electrical
infrastructure. Selecting these types of locations helps minimize long conduit and wire runs, as well as any
trenching work.
WARNING: The charging station must be installed on a level concrete base. Asphalt cannot
support the full weight of the charging station. Failure to install on a level concrete base may
cause the station to tip over, resulting in death, personal injury, or property damage.
Layout considerations:
lDetermine appropriate ground anchoring locations where concrete exists or can be installed (no
asphalt surfaces).
lConsider locations where it will be easy to add future stations.
lDetermine the best conduit layout to minimize linear conduit costs to multiple parking spaces. If
possible, avoid or minimize trenching requirements, especially more costly trenching to run conduit
under asphalt surfaces.
3

lDetermine if the existing utility service and electrical panel capacity is sufficient. Identify costs for
any necessary upgrades and/or a new dedicated electrical panel. ChargePoint recommends using a
certified electrician to evaluate available capacity and identify any upgrades that may be required.
lIf a dedicated EV electrical panel is required, choose a panel located close to the existing electrical
supply.
lMeasure cellular signal levels to ensure adequate cellular coverage at the station locations. To ensure
adequate signal strength in underground or enclosed parking structures, cellular repeaters may be
required.
lChargePoint recommends avoiding locations under trees where sap, pollen, or leaves would fall on
the charging station and increase the station owner’s site maintenance workload.
Guidelines for Different Parking Arrangements
lChoose adjacent parking spaces in an area with adequate lighting.
lConsider how easily drivers can find the stations they need to access.
lCheck local requirements for accessibility and pathway width, sometimes called “path of travel”, to
ensure that station placement does not restrict sidewalk use.
lThe maximum reach from the station to charge port on a typical vehicle is approximately 3.76 m
(12ft 4 in) (a) at a height of 0.6 m (2 ft) (b) above the ground.
lBuilding a pad into the head of a parking space (instead of on the sidewalk) is permited if local code
allows it compared to the minimum parking space length and the pad meets all pad requirements
listed in this document.
lThe Express 280 can have different charging cable types (CCS1 and CHAdeMO) to offer flexibility, or
it can have two of the same cable type. The cables cannot both charge at the same time.
4
Charging Station Placement

lTwo cable lengths are available:
oStandard length cables are 5.4 m (17 ft 8 1/2 in) long and are used with standard Cable
Management Kits (CMK)
oMedium length cables are 7.6 m (24 ft 11 1/4 in) long and are used with longer cable
management systems
IMPORTANT: Place each charging station to maximize cable reach for the varied charge port
locations on different EVs.

Note: Rear clearance must be at grade level +/- 25 mm (1 in).
Refer to Ventilation and check local and regional code for any additional clearance requirements.
11

Surface Conduit Entry
You can install Express 280 DC fast charging stations at sites where you 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 280 for
shared DC output.
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).
lThe panel breaker serving the charging station matches the site drawing requirements depending on
local code and the type of installation: 80 kW Standalone, 160 kW Paired, 62.5 kW or 50 kW de-
rated (when replacing a previous, lower-amperage system).
lThe smooth, level concrete has been approved by a structural engineer for the Express 280
dimensions and weight, OR conforms to these general specifications*:
lAt least 305 mm (1 ft) deep (or deep enough to be 305 mm (1 ft) below the frost line)
lAt least 1296 mm (4 ft 3 in) on each side
lContains #4 rebar top and bottom 305 mm (1 ft) on center
lConcrete 2500 PSI minimum
* These pad specifications are applicable in most conditions. In some extreme conditions, a larger pad
would be required.
lThe 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. Visit Connectivity for more information.
lThe service clearance of open space (not necessarily at system grade) extends a minimum of
610mm (2 ft) beyond the station in front, and 1072 mm (3 ft 6 in) side to side centered on the
station. See the images below for rear clearance depending on configuration.
