Depending on what you have ordered, the valve terminal will already be fitted screw connectors.

If the VTSA valve terminal is fitted with end plate type VABE−...R Z −...and with reversible 2x3/2−way
valves (identifier T32 F −A, T32 N −A, T32 W −A), the supply pressure must also be provided at connec−
tion 12. The valve terminal will then no longer be operated in conformity with the ISO standard.
