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 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 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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.
• 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sufcientstabilityinordertoallowtheproduct
tobexed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%
• Overow-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 xing the switchgear
The switchgear can be installed on various
structures (concrete wall, mounting rail etc.).
Forthisreason,thexationmaterialsprovidedby
the customer must be suitable for the relevant
structure.
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 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):268x188mm
• Observe the information on the underside of
the switchgear too!
3. Drilltheholesaccordingtothespecicationsfor
thexationmaterialsused.
