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 safe from high water.
•
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 switchgear
should be cleaned of dust before commissioning. If con-
densate has formed, check the individual components are
working properly. Defective components must be replaced
immediately.
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.

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 wastewater systems, ob-
serve the pertinent local regulations and directives for wastewater
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.

of explosions!
The switchgear is not approved for potentially
explosive areas and must always be installed out-
side of such areas! Failure to observe this can lead
to fatal injury due to explosion! Always have the
connection carried out by an 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 vi-
brations. 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 without any problems (no tug-
ging 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 suffi-
ciently stable to allow the product to be anchored securely
and functionally. The operator or the supplier is responsi-
ble for the provision of the foundations and their suitabili-
ty in terms of dimensions, stability and strength.
•
The following ambient conditions must be observed.
•
Ambient/operating temperature -30 ... +60 °C
•
Max. relative humidity: 50 %
•
Overflow-proof assembly
•
Check the available planning documentation (installation
plans, design of installation location, wiring diagram) is
complete and correct.
•
Please also observe the applicable national accident pre-
vention regulations and trade association safety provi-
sions.
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 pro-
vided 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 size of the borehole depends on the size 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 fixa-
tion materials used.
4.
Fix the switchgear using four screws (max. Ø: 4 mm) and
appropriate anchors onto the wall.
5.3.3. Positioning of signal transmitters
For automatic control of the connected pump, a corresponding
level control device must be installed. This needs to be provided
by the customer.
Float switches may be used as signal transmitters. Connection
of level sensors or electrodes is not possible! The corresponding
signal transmitters must be installed according to the system's
installation plan.
