General product information
Type of note
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).
