AREAS OF
APPLICATION
Submersible pumps in the MultiCut
range are suitable for effluent in pres-
sure drainage systems or for the drain-
age of single dwellings.
MultiCut pumps are principally used
for:
- effluent containing fibrous matter
- effluent containing solids (without
stones)
- domestic effluent without faecal
matter
- domestic effluent with faecal mat-
ter
- mechanically cleaned effluent
The submersible pumps are supplied
without explosion protection or with ex-
plosion protection.
When using the pumps, the relevant
national laws, regulations and stipula-
tions must be adhered to, for example:
∙ Installation of lowvoltage systems
(e.g., VDE 0100 in Germany)
∙ Safety and working
(e.g., BetrSichV and BGR 500 in Ger-
many)
∙ Safety in wastewater
(e.g., GUV-V C5, GUV-R 104, GUV-
R 126 in Germany)
∙ Electrical systems and operating re-
sources (e.g., GUV-VA3 in Germany)
∙ Explosion protection
EN 60079-0, EN 60079-1, EN 60079-
14, EN 60079-17 and EN 1127-1.
For non-standard utilisation conditions
in areas subject to explosion hazards,
please ask the local authority respon-
sible.
In Germany, this would be, for example,
the Trade Supervisory Centre (Gewer-
beaufsicht), the Technical Inspection
Agency (TÜV), the building authority
(Bauamt) or professional organisation
(Berufsgenossenschaft).
The installation and operation of this
equipment is regulated by the ordinance
concerning the protection of health and
safety in the provision of work equipment
and its use at work, concerning safety
when operating installations subject to
monitoring, and concerning the organi-
sation of industrial health and safety at
work, (Betriebssicherheitsverordnung),
Article 1.
Where no explosion protection is stipu-
lated for the pumping of foul wastewa-
ter at the installation location, pumps
without explosion protection may also
be used.

Modes of operation
with the pumped medium at a tem-
perature of 40°C:
Motor submersed: continuous opera-
tion S1
Motor emerged: short duration opera-
tion S2; see "Technical Data"
Motor emerged: intermittent operation
S3; see "Technical Data"
The submersible pump is frost-resist-
ant down to -20°C when stored in dry
conditions. When installed, however,
it must not be allowed to freeze in the
water.
Transport
The pump must always be lifted
by the handle and never by the
power supply cable! The pump
should only be lowered by using a rope or
chain.
ELECTRICAL
CONNECTION
materials
By using our controls, you can be sure
that the requirements of the EU type-
systems
testing certificate are met.
Only qualified electricians may
carry out electrical works to
the pump or the controls.
The standards applicable in each case
(e.g. EN), the country-specific regula-
tions (e.g. VDE in Germany), and the
regulations of the local supply network
operator must be observed.
ATTENTION! Never lay the end of ca-
bles in water! Penetrating water may
cause malfunctions.
Circuitry for pumps running on alter-
nating current
The alternating current pumps must
not be used without a control unit.
MultiCut pumps in alternating current
versions are protected by 2 winding
thermostats and a motor contact switch
in the AD 12 Ex ME control unit. The two
operating condensers in the control unit
must be dimensioned according to the
measurements indicated in the Type Ex-
amination Certificate.
Capacity 2 x 30 µF Tolerance ± 10%
Operating voltage 400 V , Operating
mode DB
Δ-Circuitry for low voltage
Y-Circuitry for high voltage
Y-Circuitry for high voltage, 75/2 M and
76/2 M
Alterations to the circuitry are to be
made using crimp connectors (X) be-
tween the coni plug connection (Y) and
the built-in motor. The new crimp con-
nection must be professionally made.
Only slow-blow fuses or automatic fus-
es with C or D characteristics are to be
used as pre-fuses for the pump. Nec-
essary fuse protection for direct on-line
start: 16 A, and for star-delta start 20 A
(72/2 M, 76/2 M).
