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

The external pilot air is supplied as standard via connection 14.
3)
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.
