j) An open or not securely closed plug must not be
energized in explosive areas!
k) Circuits in zone 2 may only include devices that are
suitable for operation in this zone and which have
appropriate documentation.
l) The devices must be protected against UV light.
m) The device must have a low-induction connection
with the PA in the system.
n) Operation of the valve system is only permissible in
fully assembled housings that are free of defects.
Operation in damaged housings is prohibited.
o) When ordering spare parts, include the material
number located on the devices (label, rating plate).
p) Avoid contact between external liquid or corrosive
media and the device.
q) Do not place any deflection or torsion loads on the
device.
r) The valve systems must not be used in systems
with electric corrosion protection or may only be
used on consultation with the manufacturer and
after implementing special measures.
s) Assembly work in Ex areas may only be carried out
in accordance with the local installation regulations.
Observe the following guidelines:
– Assembly and maintenance may only be done in
non-explosive atmospheres.
– Additional safety precautions are necessary if there
is a probability of hydrogen sulfide, ethylene oxide
and/or carbon monoxide. These substances have a
very low ignition energy threshold!
– Where any potential for explosion exists, only use
non-sparking tools for these substances and all
substances in explosion group IIC!
Use
The valve systems are only permitted for appropriate and
intended use. In the case of violation, all manufacturer
liability and warranty claims will no longer apply!

Service, maintenance

Definition of terms in accordance with IEC 60079-17:
Maintenance and service: A combination of all tasks
carried out to maintain an object in or return it to a
condition which corresponds to the requirements of the
respective specifications and ensures that the required
functions can be performed.
Inspection: Careful examination of the object with the goal
of making a reliable statement on the condition of the
object. Inspection is carried out without disassembly or, if
necessary, with partial disassembly, supplemented by
procedures such as taking measurements.
Visual inspection: An inspection which determines visible
faults, such as missing screws, without the use of access
equipment or tools.
Close-up inspection: An inspection which, in addition to the
faults determined by visual inspection, also determines
faults, such as loose screws, that can only be found by using
access equipment, e.g. steps (if required) and tools. For
close inspections, the housing usually does not need to be
opened and the equipment can usually stay energized.
Detailed inspection: An inspection which, in addition to the
aspects determined by close inspection, determines
faults, such as loose connections, that can only be found
by opening housings and/or using tools and testing
equipment, if required.
W
Maintenance measures may only be performed by
personnel with equal or comparable qualification acc.
to TRBS 1203.
W
Accessory parts for use in explosive areas must
comply with the requirements stipulated in the
European directives and national laws.
W
Components may only be exchanged for original spare
parts that are also approved for use in explosive areas.
W
Devices in ex areas must be cleaned regularly. The
intervals must be stipulated by the operator in
accordance with the local ambient conditions.
W
After service and/or maintenance, all barriers and
warnings must be returned to their original locations.
W
Disassemble the device as soon as malfunctions occur.
Maintenance of internal components cannot be
conducted on site. Send the device to the manufacturer
for inspection.
