3.5 General instructions on installation
Warning
Accidental movements of the connected actuator technology and uncontrollable move-
ments of loose tubing lines can cause injury to persons and/or damage to property.
• Before carrying out mounting, installation and maintenance work, switch off the
following:
– Compressed air supply
– Operating and load voltage supplies.
Note
Observe the following if the UL requirements are to be complied with in your applica-
tion:
– Rules for complying with the UL certification c an be found in the separate UL-specif-
ic special documentation. The tec hnical data listed there also apply here.
– The technical data in this documentation may show values deviating from this.
The components of the valve terminals contain electrostatically sensitive components.
The c omponents can be damaged if you touch the c ontact surfaces of the plug connect-
ors or if you do not o bserve the handling specifications for electrostatically sensitive
devices.
Note
Handle all modules and components of the MPA-S valve terminal with great care.
• Note especially the following:
– Exact placement of screws in the plastic thread (to avoid damage to thread)
– Manual screwing in of the screws
– Compliance with the specified torques
– Clean connecting services (avoidance of leaking and contact errors) and intact
seals and sealing surfaces
– Sealing of unused connections with blanking plugs to avoid contamination and
maintain reliability.
For the optimum performance of the valve terminal, we recommend that the valves should be supplied
via m ore than one supply and exhaust line if:
– more than 6 valves of size MPA1 or
– more than 3 valves of size MPA2
are switched simultaneo usly to flow.
