SCHUKO socket with surge voltage protection

Instructions for operation

- Keep cables between loads (5) and surge protection socket outlet (1) as short as possible,
max. 4 m.

- Do not lay protected cables parallel to unprotected cables. There is a danger of surge
voltage coupling.

- When performing insulation measurements on the system, all surge protection products
should always be disconnected, because otherwise the test voltage will be limited by the
protective modules, thus leading to incorrect measurements.
