General information

1 General information

The devices are to be mounted, started up

or operated only by trained and experi-

enced personnel familiar with the devices.

According to these mounting and operating

instructions, trained personnel refers to indi-

viduals who are able to judge the work they

are assigned to and recognize possible haz-

ards due to their specialized training, their

knowledge and experience as well as their

knowledge of the applicable standards.

Explosion-protected versions of this device

must be operated only by personnel who has

undergone special training or instructions or

who is authorized to work on explosion-pro-

tected devices in hazardous areas.

Proper shipping and storage are assumed.

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

Type3756BoosterValvesandvalves

accordingtoISO5999-1.Observethe

corresponding mounting instructions (see

section2.1).

The valve can be mounted in any desired

position. To ensure reliable functioning, do

notcovertheexhaustairlterintegratedinto

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

inthehorizontalposition).SeeFig.1.

On mounting, make sure that at least

300mmclearanceiskeptabovetheenclo-

sureandatleast200mmclearanceatthe

electrical connection.

WARNING

2.1 Devices with interface for

direct mounting

−Type3964-XXX000X000XX

Push the device with interface for direct

mounting onto the connecting plate () un-

derneathofthexingscrewanduseahold-

er () and a hexagon socket screw () to

fasten it. Make sure the two O-rings are

seated properly on the interface of the con-

nectingplate(seeFig.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 ()

underneaththeheadofthexingscrewand

use a holder () and a hexagon socket

screw ()tofastenit(seeFig.2).

The mounting accessories are included in

scope of delivery of the connecting plate.

The connecting plate () can be mounted

with two M3 cap screws on a mounting plate

or with one or two mounting bases () and

cap screws ()ona35mmtop-hatrail(see

Fig.2).

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.
