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.
