Elektropneumatic positioner DigiPos
5. Installation

5 . 4 Connection of the electric lines
During assembly or during the welding of valves with factory-assembled DigiPos in pipes, make sure
that the electrical connection is made only after the assembly and welding operations. During
assembly work on existing valves with mounted DigiPos this principle must be de-energized.
5 . 5 Connection of th pneumatic lines
There are two air connections on the DigiPos positioner (also refer to Figure7; page 13).
Only the air supply line requires connection after installation. The control line is mounted at the
works. As quick-fit plug connections are used, no tools are required to connect or disconnect the
air lines.
5 . 6 Installation recommendations
Minimum spacing
The distance to the next devices or the ceiling should be
at least 100 mm. The positioner can therefore be easily
accessed for servicing and also easily dismantled.

CAUTION
• The air must be filtered 5 µm and be free of water and oil. If lubricated air is used, it is recom-
mended to use ISO VG32 class 1 oil.
