When looking at the PQF-Manager from the rear, on the left side can be found a 15-pole
terminal block and on the right side an 8 pole terminal block (top-right) and a 4-pole
terminal block (bottom right). In order to make control connections to any of these
terminals, the following procedure has to be applied:
1. Push the lever of the connector backwards with a screwdriver
2. Insert the control wires (from 0.75 mm² to 2.5 mm² single core without cable shoe or
max. 1.5 mm² for multi-strand wire) in the corresponding connection hole while
keeping the pressure on the lever.
3. Release the screwdriver
4. The wire is then properly connected
