English INSTALLATION
BEWARE of moisture!
Ingress of moisture will result in damage to
the switchgear. During storage, pay attention
to the permissible humidity and ensure the
switchgear is stored so it is overow-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
qualied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 design and operation of technical sewage sys-
tems, 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. Installation types
• Wall mounting
• Floor model
• Outdoor installation with pedestal
5.3. Installation
DANGER from installation within potentially
explosive areas!
The switchgear is not approved for potentially
explosive areas and must always be installed
outside of such areas! Non-observance may
lead to fatal injury due to explosion! Always
have the connection carried out by a qualied
electrician.
The following information must be observed
wheninstallingtheswitchgear:
• Theworkmustbecarriedoutbyaqualied
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sufcient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.
• Structural components and foundations must be
ofsufcientstabilityinordertoallowtheproduct
tobexedsecurelyandfunctionally.Theoperator
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:0...+40°C
• Max.relativehumidity:50%
• Overow-proofinstallation
• 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 xing the switchgear
The switchgear can be installed on various
structures (concrete wall, mounting rail etc.).
Forthisreason,thexationmaterialprovidedby
the customer must be suitable for the relevant
construction.
Observethefollowinginstructionsforthexation
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xationmaterialisnotdamaged
during installation.
5.3.2. Assembling the switchgear
Wall mounting
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. Mark out the 4 holes on the mounting surface and
placetheswitchingdeviceontheooragain.
3. Drilltheholesusingaccordingtothexation
information using screws and anchors. If you are
usingdifferentxationmaterials,observethe
information on usage!
