Engineering notes In order to protect against accidental contact with relay connections at voltages above 42 Veff, the device must be installed in an enclosure (preferably a control panel). It must be impossible to open the enclosure without the aid of a key or tool. AC 230 V cables must be double-insulated against safety extra-low voltage (SELV) cables. Do not mix SELV / PELV and line voltage on the same terminal. Use external protection for inductive load of relay outputs.
