tobexedsecurelyandfunctionally.Theoperator
or the supplier is responsible for the 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 planning 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 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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):140x219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.
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 cus-
tomer.
Float switches may be used as signal transmitters.
Connection of level sensors or electrodes is not
possible! The corresponding signal transmit-
ters must be installed according to the system's
installation plan.
DANGER of explosions!
If the connected signal transmitters are
used in potentially explosive areas, there is a
danger of fatal injuries from explosions! The
connected signal transmitters must always be
used outside of potentially explosive areas.
Installation must always be carried out by a
qualied electrician.
Note the following:
• Whenusingoatswitches,ensurethatthesecan
move freely in the collector tank (sump, reservoir).
• The water level of the connected pump must not
fall below the minimum.
• Themaximumswitchingfrequencyofthecon-
nectedpumpmustnotbeexceeded.
5.4. Electrical connection
POTENTIALLY fatal danger due to electrical
voltage
Incorrect electrical connections can cause fa-
tal electric shocks. Electrical connections may
only be made by a qualied electrician who is
approved by the local energy supplier, in ac-
cordance with locally applicable regulations.
DANGER of explosions!
If the connected pump and signal transmitter
are used in potentially explosive areas, there
is a danger of fatal injuries from explosions!
The connected pump and signal transmitter
must always be used outside of potentially
explosive areas. Installation must always be
carried out by a qualied electrician.
NOTE
• Depending on the system's impedance and the
connectedconsumers'max.no.ofconnections/
hour,voltageuctuationsorvoltagedropsmay
occur. Always have the electrical connections
carried out by an electrician authorized by the
local energy supplier.
• Observe the installation and operating in-
structions for the connected pump and signal
transmitters.
• The mains connection current and voltage must
be as stated on the rating plate.
• All-pole disconnecting, K-type circuit breakers
must be installed!
• Max.fuseprotectiononmainsside:16A
• On switchgears without a power supply separa-
tion device ("O" version: without main switch or
plug) this must be provided by the customer!
• It is recommended a residual-current-operated
protection switch (RCD, type A, sinus wave-form
current) be installed. Observe the local laws and
regulations on this too!
• Route the power supply cable in accordance with
the valid norms and regulations and according to
the wiring diagram.
• Ground the system (switchgear and all electric
consumers) in accordance with the regulations.
