Safety
Use in line with the intended purpose
Solenoid coils of the types MKZ45-.-., installed on an armature tube, are
foreseen for he actuation of valves in explosion hazard areas. The solenoid
coils are constructed in the ignition protection class «intrinsically safe»
and have type examination certifications in accordance with ATEX, UKEX, IECEx
und CCC. The solenoid coils are foreseen for operation with intrinsically safe
electric power supplies.
Installation conditions and operating conditions have to be observed.
The solenoid coil type suitable for the application should be selected
together with the manufacturer Wandfluh AG Frutigen or his representatives.
Authorised Persons
The work described here must only be carried out by qualified persons.

In case of applications in zone 0, the solenoid coil must only be connected to
intrinsically safe electric circuits of the category ia.
In case of applications in zones 1 and 2, the solenoid coil may be connected
to intrinsically safe electric circuits of the categories is and ib.
The technical safety limit values have to be complied with (refer to Technical
data).
Applications in zone 0
The solenoid valve has to be securely fixed, e.g., by means of a stable screw
connection to supporting elements, so that it cannot move even during
switching operations.
The installation conditions in accordance with EN-60079-14, section 12.3 have
to be complied with.
The solenoid valve or any parts of it must not be utilised as separating wall for the zone 0.
If supply lines are conducted through the separating wall of the zone 0 (e.g., for installation in reservoirs) the requirements of EN 60079-26, section 4.2.5 have to be complied with.
