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 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.
5.4. 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!
6. 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.
6.1. 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.
6.2. Installation types
• Wall fixation
6.3. 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 qualified
electrician.
The following information must be observed
when installing the switchgear:
46
• This work must be performed 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.
• Structural components and foundations must be
of sufficient stability in order to allow the product
to be fixed 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: -30 ... +50 °C
• Max. relative humidity: 90 %, non-condensing
• Overflow-proof installation
• Check that the available design documentation
(installation plans, layout of the installation loca-
tion) is complete and correct.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
6.3.1. Basic advice on fixing the switchgear
The switchgear can be installed on various struc-
tures (concrete wall, mounting rail etc.). For this
reason, the fixing material which is suitable for
the relevant construction must be provided by
the customer.
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 screws. The borehole should be 5 mm
deeper than the bolt length.
• Drilling dust impairs holding strength. For this
reason, always blow out or vacuum out the
borehole.
• Make sure the fixation material is not damaged
during installation.
6.3.2. Assembling the switchgear
Fix the switchgear to the wall using 4 screws and
anchors.
1. Remove the cover from the alarm switchgear and
position the open switchgear on the mounting
surface.
2. Mark out the 4 holes on the mounting surface and
place the switchgear on the floor again.
3. Drill the holes using according to the fixation
information using screws and anchors. If you are
using different fixation materials, observe the
information on usage!
4. Fix the switchgear to the wall.
