sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium may be hot
and could cause burns.
For installations in areas subject to explosion hazards, special
regulations apply!
APPLICATION
Explosion-protected submersible pumps from the US series
are suitable for pumping highly polluted or fibrous wastewater
without stones from collection chambers or other hazardous
areas.
When using the pumps, the relevant national laws as well as
national and local regulations must be complied with, for ex-
ample:
• Installation of low voltage systems (e.g. VDE 0100 in Germa-
ny)
• 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 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 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 at the surface: short duration operation S2; see "Tech-
nical Data"
Motor at the surface: intermittent operation S3; see "Techni-
cal data"
The submersible pump is frost-resistant 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 lifted by the handle and never by
the power supply cable! The pump should only be lowered into
deeper 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.
NOTICE! Only qualified electricians may carry out electrical
works to the pump or the controls.
The relevant standards (such as EN standards), country-speci-
fic regulations (such as VDE in Germany), and the regulations of
the local power supply companies must be observed.
NOTICE! Never put the mains plug or a free lead end in water!
If water gets into the plug, this can cause malfunctions and da-
mage.
Circuitry for pumps running on alternating current (24089)
US... EX pumps running on alternating current must not be
used without a control unit.
Pumps in alternating current versions are protected by 2 win-
ding thermostats and a motor contact switch in the AD 4 XE or
AD 8 XE control unit. The two operating condensers in the con-
trol 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
