Earthing - VOLTCRAFT SW-4000 Notice D'emploi

b) Earthing
Observe:
This section does not apply to the converter "SW-100" (item no. 511700), since it only has a Euro socket.
Connect only a device with protection class II to it.
When connecting devices of protection class I (devices with protective ground plug or PE connection), the earthing
of the converter output can be performed via the minus connection of the converter or rechargeable battery. For the
converter "SW-150", a screw connection separately placed at the housing (marked with earthing symbol) can be
used.
Observe that the metal parts of the housing and the PE connection of the protective ground socket are connected
internally to the minus terminal ("-") of the rechargeable battery connection. The zero conductor connection on the
output side must never be earthed.
If an earthing line (green/yellow cable) is used, it must have a cross-section of at least 6 mm²; keep the cable as
short as possible.
