On a dual-connector station, the signage problem is not decoration — it is correspondence. One cabinet serves two bays, so a driver must match the bay they parked in to the connector that serves it, every time, in the dark and in the rain. The fix is one naming scheme repeated in four places: connector labels on the station, numbers painted in the bays, the station’s platform listing, and the sign’s instructions. When all four agree, drivers pick the right connector on the EV-AC03201T without thinking; when they disagree, sessions start on the wrong connector.
Key Takeaways
- The dual-connector signage problem is correspondence: bay, connector, listing and sign must carry one identical name per connector.
- A driver at the station needs four answers — which connector, how to start, what it costs, who helps — each with a planned home.
- The touchscreen confirms the choice the labels suggest; the RFID point is the second way in.
- Marking colours, symbols and duties are local confirmations — settle them with your authority first, then apply your scheme.
One Name for Each Connector, Used Everywhere
Pick the scheme once. Whether the connectors are “1” and “2”, “A” and “B”, or named after their bays, the same identifier must appear:
- On the station itself — beside each connector’s dock, large enough to read from inside the car.
- In the bay — the painted number or letter on the ground or kerb, visibly the same word as the connector’s name.
- On the platform listing — the name a driver sees before arriving should match the ground, not a back-office asset code.
- On the help sign — fault reports naming the connector (“Connector 2 won’t start”) get fixed faster.

What a Driver Must Learn Standing at the Station
| The driver’s question | Where the answer lives | The decision behind it |
|---|---|---|
| Which connector is mine? | The matching connector and bay labels, confirmed on the 7-inch touchscreen as the session starts | One scheme, repeated — the screen confirms the choice the labels suggested |
| How do I start? | A short instruction line at the station: tap an RFID card or follow the touchscreen | Two stated ways in — say both, in the order a first-timer should try them |
| What does it cost? | The operator’s tariff, shown at the station or on its platform listing | The price is the operator’s own; the decision is that it is visible before the session starts |
| Something is wrong — who helps? | A help contact on the station sign | A named contact turns a failed session into a fault report, not a bad review |
Marking Decisions Are Yours; Marking Rules Are Not
This article deliberately sets no standards. Bay colours, symbol designs, sign dimensions, wording duties and enforcement differ by place and are set by your local authority and advisers — confirm them before paint is bought, not after. The same applies to accessible bays, whose layout requirements are likewise a local confirmation. What needs no rulebook is the correspondence discipline above: whatever scheme the rules produce, station, bays, platform and sign must tell one identical story. Placement — sightlines from the entrance, lighting over the labels — belongs to the siting work in our site selection guide.
The Station at the Centre of the Signs
The EV-AC03201T is a floor-standing AC station with two Type 2 connectors sharing up to 43 kW (22 kW per connector), a 7-inch touchscreen, RFID access and an OCPP 1.6J connection to the operator’s platform. The touchscreen is the confirmation surface — where the chosen connector, the session and the tariff come together — and the RFID point is the second way in. How the platform side works is explained in how commercial charging stations work.
Frequently Asked Questions
Does it matter whether the connectors are numbered or lettered?
No — consistency matters, the alphabet does not. One scheme, repeated identically on station, bays, listing and sign, stops wrong-connector sessions. Mixed schemes — numbers on the ground, letters on the cabinet — are the usual cause.
What happens if a driver starts a session on the wrong connector?
The session runs on the connector they selected, which may sit across the cabinet from their car: a stretched cable, a blocked neighbouring bay, or a second driver puzzled by a live connector. Matching labels and the touchscreen’s confirmation step catch the mismatch before energy flows.
Are there official colours or symbols we must paint in the bays?
That depends on where your site is — a question for your local authority and advisers, since marking and signage requirements are not the same everywhere. Decide the rules first, then apply your naming scheme inside them.
