Areas Of Application; Electrical Connection - Pentair Jung Pumpen MULTISTREAM 150/4 C3 Originalbetriebsanleitung

For installations in areas subject to explosion hazards, special
regulations apply!

AREAS OF APPLICATION

Submersible pumps in the MultiStream range are suitable for
pumping wastewater in municipal and industrial pumping sta-
tions, and in rainwater retention tanks.
MultiStream pumps are favoured for use with:
– wastewater containing fibres
– wastewater containing solids (without stones)
– mixed wastewater
– untreated water
– raw sludge
– surface water and rainwater
The submersible pumps are supplied without explosion pro-
tection or with explosion protection.
When using the pumps, the relevant national laws, regulations
and stipulations must be adhered to, for example:
• Installation of low-voltage 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 and
GUV-R 126 in Germany)
• Electrical systems and operating resources (e.g., GUV-V A3
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, (Betriebs sicherheitsverordnung), Article 1.
Where no explosion protection is stipulated for the pumping
of foul wastewater at the installation location, pumps without
explosion protection may also be used.
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

Circuitry
/
Alterations to the circuitry are to be made using crimp con-
nectors (X). The new crimp connection must be professionally
made.
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.
Only slow-blow fuses or automatic fuses with C or D charac-
teristics are to be used as pre-fuses for the pump. Necessary
fuse protection for for star-delta start 35 A and 50 A for pumps
300...
The pump must be protected via an overload trip. Setting for
for star-delta start = nominal current x 0.58.
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.
Thermostat connection without explosion
protection
The thermostats are to be connected in such a way that the
motor is switched off via the control circuit when the response
temperature is reached. The motor is switched on again auto-
matically after the winding has cooled down.
Thermostat connection with explosion
protection
The thermostats are to be connected in such a way that the
