Mounting the supply pressure regulator
5 Mounting the supply pressure
regulator
Î To prevent excessive amounts of con-
densed water from collecting, keep the
distance between the compressor and
supply pressure regulator as short as
possible.
The supply pressure regulator can either be
mounted directly in the pipeline of the air
supply or on rails or brackets using the cor-
responding mounting parts (see accessories
in section 3.3).
Î Observe the flow direction of the supply
air. An arrow on the nameplate indicates
the direction.
Depending on how the regulator is installed
in the pipe, it may be necessary to mount the
pressure gauge at the back of the supply
pressure regulator (see section 5.1.1).

5.1 Pneumatic connections
The air connections (supply and output, see
Fig. 1 on page 9) are designed either
with ISO-228/1 - G ½ or ½-14 NPT
threads.
The second pressure gauge on the back of
the regulator can be used to additionally
supply pilot valves with a constant supply
pressure. This connection at the back has a
G
thread.
