Installing a DC fast charger: preparation and wiring
What to arrange up front: grid power, foundation, cooling and inspection.
- 01
Start with the grid
A DC unit needs three phase power and, at high output, its own transformer. Ask the grid operator for the available capacity early: it is usually the longest lead time in the project.
- 02
Foundation and placement
Provide a level foundation with ducts, room for the doors and free airflow around the unit. In the distributed systems the power cabinet sits away from the dispensers.
- 03
Cable routes
Between cabinet and dispensers the distance sets the cable size. Fix this in the drawing before the concrete work starts.
- 04
Cooling and noise
The DH480 runs without a fan, the DT800 and DT1500 are liquid cooled. Near homes, deliberately pick a quiet version and a good position.
- 05
Connecting to the platform
As with AC, we deliver the unit configured for your OCPP url and can follow up together through proxy urls.
- 06
Inspection and handover
Have the installation inspected under local rules, test every charge point with a vehicle or tester and document the measured values.
