Covering up unused connections
You must seal off any connections which are not required with M12 screw caps, in
order to ensure that the degree of protection (IP 65) is achieved.
Switch-on sequence
The 4/2-way valve is not of the contention-free type.
Consequently, it is important to switch on the compressed air supply first, and then
switch on the voltage.
