English INSTALLATION
BEWARE of moisture!
Ingress of moisture will result in damage to
the switchgear. During storage, pay attention
to the permissible air humidity and ensure the
switchgear is stored so it is overflow-proof.
• The switchgear must be protected from direct
sunlight, heat and dust. Heat or dust can cause
damage to electrical components!
• Following a longer period of storage, the switch -
gear should be cleaned of dust before commis-
sioning. If condensate has formed, check the
individual components are working properly.
Defective components must be replaced imme-
diately.
4.4. Return delivery
Switchgears which are returned to the plant must
be clean and correctly packaged. The packaging
must protect the switchgear from damage during
transportation. If you have any questions, please
contact the manufacturer.
5. Installation
In order to prevent damage to the switchgear or
serious injury during installation, the following
points must be observed:
• Installation work – assembly and installation
of the switchgear – may only be carried out by
qualified persons. The safety instructions must be
followed at all times.
• The switchgear must be inspected for transport
damage before carrying out any installation work.
5.1. General
For planning and operation of technical sewage
systems, observe the pertinent local regulations
and directives for sewage technology (such as
those of the German Association for Water,
Wastewater and Waste).
When adjusting level control devices, make sure
that connected pumps have the minimum water
coverage.
5.2. Types of installation
• Wall-mounted installation
5.3. Installation
DANGER due to explosive atmosphere!
The switchgear is not approved for potentially
explosive areas and must always be installed
outside of such areas! Failure to observe
this can lead to fatal injury due to explosion!
Always have the connection carried out by
a qualified electrician.
The following information must be observed
when installing the switchgear:
• The work must be carried out by a qualified
electrician.
• The installation location must be clean, dry and
free of vibrations. Avoid exposing the switchgear
to direct sunlight.
• The customer must provide the power supply
cables. These must be of sufficient length so that
connection to the switchgear is possible with-
out any problems (no tugging on the cable, no
kinking, no crushing). Check whether the cable
present is long enough for its cross-section and
its installation type.
• When using the "S" version, a suitable sock -
et must be installed within a 1 m radius of the
switchgear.
• Structural components and foundations must be
of sufficient stability in order to allow the product
to be fixed securely and functionally. The opera -
tor or the supplier is responsible for provision of
the foundations and their suitability in terms of
dimensions, stability and strength.
• The following ambient conditions must be ob-
served:
• Ambient/operating temperature: -30 ... +60 °C
• Max. relative humidity: 50 %
• Overflow-proof assembly
• Check the available consulting documentation
(installation plans, design of installation location,
wiring diagram) is complete and correct.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
5.3.1. Basic advice on fixing the switchgear
The switchgear can be installed on various
structures (concrete wall, mounting rail etc.).
For this reason, the fixation materials provided by
the customer must be suitable for the relevant
structure.
Observe the following instructions for the fixation
material:
• Ensure the proper edge clearance in order to
prevent the construction material from tearing or
chipping.
• The depth of the borehole depends on the length
of the bolts. The borehole should be 5 mm deeper
than the bolt length.
• Drilling dust impairs holding strength. Therefore:
Always blow or vacuum out the borehole.
• Make sure the fixation material is not damaged
during assembly.
5.3.2. Assembling the switchgear
Wall-mounted installation
Fix the switchgear to the wall using 4 screws and
4 anchors.
1. Open the cover on the switchgear and place this
on the intended assembly area.
2. Draw the four holes on the assembly area.
• Drilling distances (WxH): 140x219 mm
• Observe the information on the underside of
the switchgear too!
3. Drill the holes according to the specifications for
the fixation materials used.
