Safety instructions

EB 3962-1 EN 3

General safety instructions

➢ The solenoid valves are to be assembled, started up or operated only by trained

and experienced personnel familiar with the product.

According to these mounting and operating instructions, trained personnel is
referred to as individuals who are able to judge the work they are assigned
to and recognize possible dangers due to their specialized training, their
knowledge and experience as well as their knowledge of the applicable
standards

.

➢ Proper shipping and storage are assumed.

➢ Explosion-protected solenoid valve versions are to be operated only by per-

sonnel who has undergone special training or instructions or who is author­ized to work on explosion-protected devices in hazardous areas

.
For technical data, order specifications, spare parts and accessories refer to
Data Sheet T 3962.

➢ Make sure the maximum permissible supply pressure is not exceeded. If neces-

sary, reduce the supply pressure using a suitable supply pressure regulator.

➢ The solenoid valves can be installed in any desired position. Make sure the filter

in the lid and the cable entries point vertically down. If this mounting position is
not possible, install the solenoid valves with the filter and cable entries in hori­zontal position.

Important!

➢ For installation and maintenance work on the solenoid valves, make sure the

relevant plant section has been depressurized and, depending on the pro­cess medium, drained as well. Due to the high surface resistance, avoid
electrostatic charging when mounting or servicing the solenoid valves in
hazardous areas. Do not loosen the enameled screws on the housing.

➢ The solenoid valves can be mounted on rotary actuators, linear actuators or

control valves with a NAMUR rib using mounting kits. Observe the associ­ated mounting instructions.

Mounting

1Mounting

1.1 Wall mounting

Types 3962-9XXX13 and 3962-9XXX14

The solenoid valves can be mounted using
the through holes and screws.

1.2 Mounting on rotary actuators
with NAMUR interface acc. to
VDI/VDE 3845

Type 3962-9XXX0

The solenoid valves can be mounted on
rotary actuators with NAMUR interface us­ing the following adapter plates (Fig. 3):

– 1400-9741 for ¼” or
– 1400-9743 for ½”.

The adapter plates are not included in the
scope of delivery.

Before mounting, check that the two O-rings
are properly positioned. Use the grub screw
to adjust the direction of action on the con­necting flange of the rotary actuator. Use
two screws for attachment.

1.3 Mounting on linear actuators
with NAMUR rib acc. to
IEC 60534-6-1 using adapter
plates

Type 3962-9XX00

The solenoid valves can be mounted on lin­ear actuators with NAMUR rib using ad­apter plates (Fig. 4). When additionally
mounting positioners or limit switches on lin­ear actuators in DN 50, an additional
bracket is required (order no. 0320-1416).

1.4 Mounting on linear actuators
using CrNiMo pipe fittings

Types 3962-9XX0130 and 3962-9XX0142

The solenoid valves can be mounted on lin­ear actuators (e.g. SAMSON Type 3271 or
Type 3277) using CrNiMo pipe fittings
(Fig. 5). For mounting instructions on the
SAMSON actuators, refer to Mounting and
Operating Instructions EB 8310 EN and
EB 8311 EN.
