WARNING ● ● ● ● The relay circuits have no internal fuse. An external supply line fuse is required (for fuse set of Q2 and Q3, refer to basic documentation A6V11276161). Do NOT mix SELV / PELV and mains power on the same terminal block. Use external protection for inductive load. Avoid negative voltages at the analog inputs since conversion leads to undetermined results. Maintain clearing distance of 6.4mm between SELV/PELV and mains power when different terminal blocks are used.
