The Zaptec chargers have a built-in RCD self-test you can run through the app anytime. Depending on your market and installation requirements, professional external testing may also be required during initial commissioning.
Built-in RCD self-test
Zaptec chargers automatically run an RCD test before every charging cycle. But if you want to verify the RCD is working, you can run the test manually through the Zaptec App.
The test can only be performed when a car is charging.
How to run the test:
- Open the Zaptec App and connect to your charging station via Bluetooth.
- Go to Advanced settings and select RCD Test Device.
- Click the Test button.
This will interrupt the current charging session. Your charging station will show a red light if the test is successful, and the app will display a "Ground fault detected" message. This is normal, and it confirms the RCD is doing its job.
After the test, disconnect the charging cable to reset the charger, then reconnect your car to resume charging.
Not able to perform test?
If the test button doesn't appear or you get an error when trying to use it, check these:
- Charing is not active. The test only works when a car is actually charging. Make sure charging isn't scheduled to start later.
- Firmware is out of date. The charger's firmware must be version 2.0.3.4 or above (Zaptec Go) or 4.5.2.0 or above (Zaptec Pro)
How to perform RCD test according to installation regulation 1082 and standard HD60364 in Denmark
When installing a Zaptec Pro charger for a customer installation in Denmark, verify it meets Installation Regulation 1082 and Standard HD60364 using this procedure. This testing is part of your initial verification responsibility and must be completed before the charger goes into service.
This section applies only to installations in Denmark. Installers in other markets should follow their local regulations.
Compliance testing using external equipment:
Before starting, check if authentication is active on your installation level:
- If authentication is NOT active: Add the charger to the installation, then conduct the RCD test before activating authentication on the charger.
- If authentication IS active: Add the charger to the installation, set the charger in stand-alone mode, conduct the RCD test, then remove stand-alone mode.
What you'll need:
- An RCD tester compliant with EN/IEC 62423 (such as Metrel MI 3155)
- A Type 2 tester with 4mm sockets (such as Megger 1013-317)
Test procedure:
- Connect the RCD tester via a Type 2 tester to the charger.
- Move the CP state from A to C to close the relays in the charger.
- Perform your first RCD test point.
- After each test point, move the CP state back to A, then to B. Wait until the charger LED is blue, then move to state C again.
- Conduct the next RCD test point.
The charger does not automatically reconnect after testing with a Type 2 adapter. You must manually change the pilot state each time.
According to HD60364, you are responsible for testing all RCD properties during the initial verification, following the applicable regulations in your country.
Product-specific notes
Zaptec Pro: Supports both the built-in self-test via the app and external testing for compliance verification.
Zaptec Go: Supports the built-in self-test via the app. External professional testing follows the same principles, though Zaptec Go is typically used in home installations where this level of verification may differ.
