Conduit and Anchor Bolt Configuration

Each Express 250 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.

You can choose one of the following configurations:

Each Express 250 communicates with ChargePoint via a cellular network. No communication wiring is needed between the station and the building.

Standalone Configuration

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.

Paired Configuration

If two Express 250 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 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 communicates with ChargePoint via a cellular network. No communication wiring is needed between the station and the building.
