ENGLISH
APPLICATION
Explosion-protected
pumps from the US series are suitable
for pumping highly polluted or fibrous
wastewater without stones from col-
lection chambers or other hazardous
areas.
When using the pumps, the relevant na-
tional laws as well as national and local
regulations must be complied with, for
example:
∙ Installation of low voltage systems
(e.g. VDE 0100 in Germany)
∙ 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 re-
sources (e.g., GUV-V A2 in Germany)
∙ Explosion protection EN 60079-0:
2009, EN 60079-1: 2007, EN 60079-
14: 2008, EN 60079-17: 2007 and EN
1127-1: 2011
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
(Gewerbeaufsicht), the Technical In-
spection Agency (TÜV), the building au-
thority (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 organi-
sation of industrial health and safety at
work, (Betriebssicherheitsverordnung),
Article 1.
Modes of operation
with the pumped medium at a tempera-
ture of 40°C:
Motor submersed: continuous opera-
tion S1
Motor at the surface: short duration
operation S2; see "Technical Data"
Motor at the surface: intermittent op-
eration S3; see "Technical data"
The submersible pump is frost-resist-
ant down to -20°C (-4°F) when stored in
dry conditions. When installed, however,
it must not be allowed to freeze in the
water.

Transport
The pump must always be lift-
submersible
ed by the handle and never by
the power supply cable! The
pump should only be lowered into deep-
er chambers or pits using a rope or
chain.

Electrical connection

By using our controls, you can be sure
that the requirements of the EU type-
testing certificate are met.
Only qualified electricians may
carry out electrical works to
the pump or the controls.
The relevant standards (such as EN
standards), country-specific regulati-
ons (such as VDE in Germany), and the
regulations of the local power supply
companies must be observed.
Attention ! Never put the mains plug or
a free lead end in water! If water gets
into the plug, this can cause malfunc-
tions and damage.
Circuitry for pumps running on alterna-
ting current (24089)
US... EX pumps running on alternating
current must not be used without a con-
trol unit.
Pumps in alternating current versions
are protected by 2 winding thermostats
and a motor contact switch in the AD
4 Ex ME or AD 8 ExW control unit. The
two operating condensers in the control
unit must be dimensioned according to
the measurements indicated in the Type
Examination Certificate.
Capacity 8 µF or 20 µF
tolerance ± 10%
Operating voltage 400 V
Operating mode continuous operation
Circuitry for low voltage (23291)
Circuitry for high voltage (23290)
Alterations to the circuitry are to be
made using crimp connectors (X) bet-
ween 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 fu-
ses with C or D characteristics are to be
used as pre-fuses for the pump. Neces-
sary fuse protection for direct on-line
start: 16 A.
The pump must be protected via an
overload trip. Setting for direct on-line
start = nominal current, and for star-
delta start = nominal current x 0.58.

gered, the cause of the malfunction
