For installations in areas subject to explosion hazards, special
regulations apply!
AREAS OF APPLICATION
Submersible pumps in the MultiCut range are suitable for the
drainage 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 matter
–
mechanically cleaned effluent
The submersible pumps MultiCut ... TAN, EX are supplied with
explosion protection.
When using the pumps, the relevant national laws, regulations
and stipulations must be adhered to, for example:
•
Installation of lowvoltage systems (e.g., VDE 0100 in Ger-
many)
•
Safety and working materials (e.g., BetrSichV and BGR 500 in
Germany)
•
Safety in wastewater systems (e.g., GUV-V C5, GUV-R 104,
GUV-R 126 in Germany)
•
Electrical systems and operating resources (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 ex-
plosion hazards, please ask the local authority responsible.
In Germany, this would be, for example, the Trade Supervisory
Centre (Gewerbeaufsicht), the Technical Inspection Agency
(TÜV), the building authority (Bauamt) or professional organi-
sation (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 organisation of industrial health and safety at
work, (Betriebssicherheitsverordnung), Article 1.
Modes of operation
with the pumped medium at a temperature of 40°C:
Motor submersed: continuous operation S1
Motor emerged: short duration operation S2; see "Technical
Data"
Motor emerged: intermittent operation S3; see "Technical
Data"
The submersible pump is frost-resistant 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 never be lifted by the power supply cable! The
pump should only be lowered by using a chain.
ELECTRICAL CONNECTION
By using our controls, you can be sure that the requirements of
the EU type-testing certificate are met.
NOTICE!
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 regulations (e.g. VDE in Germany), and the regulations
of the local supply network operator must be observed.
NOTICE!
Never lay the end of cables in water! Penetrating wa-
ter may cause malfunctions
.
Alterations to the circuitry are to be made using crimp con-
nectors (X) between the coni plug connection (Y) and the built-
in motor. The new crimp connection must be professionally
made.
Only slow-blow fuses or automatic fuses with C or D character-
istics are to be used as pre-fuses for the pump. Necessary fuse
protection for direct on-line start: 16 A.
Δ-
Circuitry for low voltage
Y-Circuitry for high voltage
The pump must be protected via an overload trip. Setting for
direct on-line start = nominal current.
If the protective device has been triggered, the cause of the
malfunction must be eliminated before switching on again.
Coil thermostats
NOTICE!
In addition to the overload trip or protective switch
of the motor, the thermostats integrated in the motor winding
must also be connected.
The thermostats are suitable for 250
V / 1.2 A (cos phi = 0.6) and are labelled 30 and 32 for connection
purposes.
For this reason, after the protective device has been triggered,
the mains cable must be unplugged before remedying the
cause of the failure, as otherwise the pump will be automati-
cally switched on again.
