Express 250 Basic Operation
This guide describes how to operate and maintain the ChargePoint® Express 250 DC fast charging
station as a station owner or facility manager.
For full charging station specifications and ratings, refer to the Express 250 Data Sheet at:
chargepoint.com/support/guides/
Power On the System
The Express 250 charging station is powered on by the installation team at the site’s electrical panel,
immediately after completing installation. The charging station does not have a separate power
switch.
When power is turned on at the panel after it is first installed, the station runs a self-diagnostic that
includes:
•Electrical safety checks
•Lighting checks
•Display panel visual checks
•Component operation checks (such as fans and contactors)
•Installation Wizard process (allows installer to complete configuration and pinpointing of the
station on user maps)
•Network connectivity checks
When power is turned on at the panel after servicing or a power outage, the station runs a self-
diagnostic to ensure safe and correct operation:
•Electrical safety checks
•Lighting checks
•Display panel visual checks
•Component operation checks (such as fans and contactors)
•Network connectivity checks
If any errors are found, the station displays error codes on the website dashboard. See Section 3 for
further information on diagnostics.

2
Power Off the System
The Express 250 does not need to be powered off except during service. The charging station does
not have a separate power switch. The service technician turns off power at the electrical panel
before beginning work. There is no need for a software command to power off the station; hardware
is not harmed by disconnecting the circuit’s breaker.
Shunt trip wiring (wires that can be run to a separate disconnect switch) is available as a standard
feature on the Express 250. Whether this feature is used, and where the switch is located, varies by
site. For more information on how shunt trip wiring is designed and implemented, refer to the
Express 250 Site Prep Guide and the Express 250 Installation Guide. For more information on
diagnosing circuit trips, see Section 3 of this guide.
Configure System Behavior
ChargePoint offers its station owners a variety of software features to customize operation, such as:
•How to set pricing and billing methods for station use
•Who is allowed to use the station
•Waiting lists if the station(s) are already full
•How to display simple messages on the station
All configuration is done on the ChargePoint website for station owners. You are issued a username
and password during the station purchase process. Log in at:
na.chargepoint.com/admin/dashboard
or
eu.chargepoint.com/admin/dashboard
Important: You must be a licensed electrician and complete an online training class to
become a ChargePoint Certified Installer or Service Technician, and to get a login for
ChargePoint. If you do not complete this training, you are unable to complete installation
or service procedures.
Go to: chargepoint.com/installers
DANGER: RISK OF SHOCK. Before performing any procedure, the technician must
disconnect the power to the Express 250 at the service panel. 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. Keep power off for the
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.

Scope of Maintenance
Responsibility for Maintenance
The ChargePoint Express 250 charging station needs minimal preventative maintenance over its
lifetime. ChargePoint’s network connection monitors for system health and sends an alert when
corrective maintenance might be required.
Maintenance can be performed by ChargePoint technicians if the station is covered by an Assure
maintenance agreement; otherwise, the customer can send their own technicians for training to
become certified by ChargePoint to perform the work. For more information on service certification,
see: chargepoint.com/installers
Site Manager’s Responsibilities
The site or facility manager where the ChargePoint charging station is installed has a few minimal
duties for general site maintenance:
•Ensure the station is free of debris or any substance blocking the front and rear vents.
•Keep snow below 0.25 m (10 in) to ensure proper ventilation.
•Check each station monthly for vandalism or damage. If the station is marked, contact
ChargePoint for replacement signs. If the station appears damaged, contact ChargePoint for a
service visit.
•Check each charging cable monthly for any signs of wear or damage. If a cable appears
damaged, contact ChargePoint for a service visit.
CAUTION: Do not pressure wash the charging station. Pressurized water could damage the
system. To clean the charging station, use a damp cloth.

Preventative Maintenance
ChargePoint, or a ChargePoint certified technician, should perform service checks at the intervals
listed below.
Yearly Maintenance
•Check signs for marks or fading, and replace if needed.
•Use a damp, lint-free cloth to wipe down the outside surfaces of the station, including the
cables, outer surfaces of the connector, and touchscreen.
•Perform a test charge and check for proper operation.
•Check coolant levels and top off if needed.
•Check the body of the charging station for any signs of rust or damage, and contact
ChargePoint if found.
•Check the cables and connectors of the charging station for any signs of damage. If damage is
found, do not use the station and contact ChargePoint.
•Check the area light bar and LED display for burned-out lights. Replace if needed using the
appropriate FRU guides.
5-Year Maintenance
•Perform all yearly maintenance listed above.
•Replace coolant.
•Check correct torque on mounting anchors and cable tabs in the contactor assembly, using the
appropriate Installation and FRU guides.
10-Year Maintenance
•Perform all yearly and 5-year maintenance listed above.
•Check charging cables for any degradation and replace if needed using the appropriate FRU
guides.
DANGER: RISK OF SHOCK. Any maintenance that requires any removal of panels must be
done when the system is de-energized. Turn off the circuit breaker and do not restore
power until maintenance is complete and the unit is completely reassembled. FAILURE
TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY OR LOSS OF LIFE.
