Table19: PRCDtests
The PRCD cannot be switched on without mains voltage due to undervoltage tripping.
PRCDs of typeAC only detect pure sinusoidal currents and are therefore no longer approved in
Germany according to VDE0100‑530. The contact current measurement of the PRCDs is
carried out with a testing voltage of 230V‑AC and a testing current up to a maximum of 90μA.

A portable power distributor is intended for power supply at different locations and often
includes an RCD (residual current protection device) and MCB (line safety switch).
The test procedures 19and20 available in the device include the necessary test steps that
apply to a large number of commercially available power distributors.
Please note that the admissible limits and test steps of the test procedures available in the
device might be different from the necessary limits and test steps of the switches used in the
power distributor (RCD, MCB,...).
For testing, you can proceed as follows:
• Automatic test using an existing test procedure [}page39]
(test procedure 19or20; depending on the RCD installed in the test sample)
• Automatic test using a customer-specific test procedure
• Manual test including all necessary individual tests [}page77].
7.8 Remote control
The remote control function mirrors the user interface of the device to an external end device
(e.g. smartphone, tablet or PC) and allows the device to be controlled via the end device used.
This function supports training consultants or qualified electricians in instructing trainees on the
functional scope of the device.
The device can be controlled remotely using the following options:
• Remotely controlling the device via WLAN using a smartphone or tablet [}page119]
• Remotely controlling the device via LAN using a PC [}page118]
Please note that it is not possible to use the device via WLAN and LAN simultaneously.
