4.3. Storage
On delivery, switchgears may be placed into tem-
porary storage for up to 1 year until use providing
the details below are observed.
The following should be taken into consideration
for storage:
• Place the packaged switchgear on a firm subsur-
face.
• Our switchgears may be stored at -10°C to +50°C
at a max. relative humidity of 50 %. The store
room must be dry. We recommend a frost-pro-
tected room for storage with a temperature
between 10°C and 25°C and a relative humidity of
40% to 50%.
Avoid condensation!
• Seal the threaded cable connections securely to
prevent ingress of moisture.
• Connected power supply cables should be pro-
tected against kinking, damage, and moisture.
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.
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 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 fixation
• 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 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.
• 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: 0 ... +40 °C
• Max. relative humidity: 50 %
• Overflow-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 fixing the switchgear
The switchgear can be installed on various
structures (concrete wall, mounting rail etc.).
For this reason, the fixation material provided by
the customer must be suitable for the relevant
construction.
Observe the following instructions for the fixation
material:
• Ensure the proper edge clearance in order to
prevent the construction material from tearing or
chipping.
