Notes
Note on application
For safe conductor connection, always adhere to a defined
tightening torque. Particularly in the case of PCB terminal blocks
with two or three positions, the individual solder pin for each
contact point cannot compensate for this. That is why the
terminal blocks must be supported during conductor connection
(held with one hand, support on the housing).
