Installation
2 Installation
Before installation, depressurize the relevant
plant section.
Do not open the enclosure.
Solenoid pilot valves with an interface for
direct mounting can be mounted on
connecting plates. Solenoid pilot valves with
CNOMO adapter plate can be mounted to
Type3756BoosterValvesandvalves
accordingtoISO5999-1.Observethe
corresponding mounting instructions (see
section2.1).
The valve can be mounted in any desired
position. To ensure reliable functioning, do
notcovertheexhaustairlterintegratedinto
the enclosure. Mount the cable socket in such
a way that the cable gland faces downward
(in cases where this is not possible, mount it
inthehorizontalposition).SeeFig.1.
On mounting, make sure that at least
300mmclearanceiskeptabovetheenclo-
sureandatleast200mmclearanceatthe

fasten it. Make sure the two O-rings are
seated properly on the interface of the con-
nectingplate(seeFig.2).
Any device spaces on the connecting plate
that are not used must be covered by a dum-
my plate () and the output port sealed by a
screw plug (). Push the dummy plate ()

3 Pneumatic connection
Run and attach the connecting lines and
screw joints according to good professional
practice. Check them for leakage and dam-
age at regular intervals and repair them, if
necessary. Before starting any repair work,
depressurize any open connecting lines.
The maximum permissible pilot supply pres-
sure must not be exceeded.
