Express Plus Power Link 1000
The Power Link 1000 receives DC input from an upstream component called a Power Block or Power Hub that centralizes AC to DC power conversion for multiple stations.
If the quantity listed in the table is a range or option, check the site drawings.
Install four Power Link anchor bolts: two at the front-center edge of the template and two near the middle.

Express 250 and Express 280
Each Express 250 or Express 280 station requires AC power from the site’s electrical panel. That AC conduit includes a ground conductor.
Optional shunt trip wiring can run from the station to the breaker panel. Check the site drawings for this.
Install four anchor bolts, with two at the front (nearest parking lot) and two at the rear of the template.
Standalone or Paired
The standalone configuration uses only the conduit for AC input.
Stations in a paired configuration also run a DC conduit and Ethernet between the paired stations.
Each Express 250 orExpress 280 communicates with ChargePoint via a cellular network. No communication wiring is needed between the station and the building.

Paired Express 250 and Express 280 Configuration
If two Express 250 or two Express 280 charging stations are “paired,” they share DC power to allow faster (higher amperage) charging to a vehicle as needed.
For a paired configuration, follow the diagram. In addition to the Express 250 or Express 280 Standalone Configuration requirements, you must also run two additional conduits between the paired stations: an Ethernet wire for communication and a conduit for DC conductors.
Each Express 250 or Express 280 communicates with ChargePoint via a cellular network. No communication wiring is needed between the station and the building.
