General
This KSB pump set has been developed in accordance with
state-of-the-art technology; it is manufactured with utmost care
and subject to continuous quality control.
These operating instructions contain important information for
reliable and safe operation of the pump.
This pump set must not be operated outside its specified oper-
ating range. The limits stated in the documentation must not be
exceeded under any circumstances.
Non-compliance with this operating manual will lead to forfeit-
ure of any and all rights to claims for damages.
If you need any additional information or instructions exceeding
the scope of this manual or in case of damage please contact

Safety
2.1
Safety instructions
Non-compliance with the safety instructions laid down in this
chapter on ”Safety” and other chapters of this operating manual
may result in hazards to persons and damage to property for
the operator and/or third parties.
Notes on using the operating manual:
- All personal involved in the assembly, installation and main-
tenance of the unit must be
thoroughly familiar with these
operating instructions.
- The operating manual must always be kept close to the loca-
tion of operation of the machine for easy access.
2.2
Personnel qualification and training
All personnel involved in the operation, maintenance, inspec-
tion and installation of the unit must be fully qualified to carry out
the work involved. The operator is responsible for assigning
personnel and providing appropriate training and instruction.
The operator may commission the manufacturer / supplier to
take care of such training. In addition, the operator is respon-
sible for ensuring that the instructions of this operating manual
are observed.
2.3
Compliance with statutory safety requirements
These operating instructions do not take into account local re-
gulations; responsibility for compliance with such regulations
lies with the operator.
Small children and persons who are mentally or physically un-
able to comply with the safety regulations shall be kept away
from the pump.
Instructions which must be adhered to when the pump is
installed in potentially explosive atmospheres are
specially marked with the symbol
2.4
Safety instructions for work on the machine
Work on the machine / unit must be carried out only during
standstill. The shutdown procedure described in the manual for
taking the unit out of service must be adhered to without fail
(section 6.2).
Pump sets handling liquids posing health hazards must be de-
contaminated.
Immediately following completion of the work, all safety-rel-
evant and protective devices must be re-installed and / or re-
activated. The instructions given in section 6 shall be adhered
to.
If the pump/unit is located in a potentially explosive at-
mosphere, it is imperative to make sure that any oper-
ation of the unit outside its design data and operating limits is
absolutely prevented. Non-compliance with this requirement
may result in the given temperature classes being exceeded,
sparking, leakage of explosive mixtures and therefore ex-
plosions.
- Make sure to prevent dust from collecting in hazardous
amounts on the unit, especially in areas of high surface tem-
perature.
2.5
Repair and modification work
Repair and modification work on the pump set are only per-
mitted after consultation with the manufacturer. Original spare
parts and accessories authorized by the manufacturer ensure
safety.
The use of other parts will lead to forfeiture of any and all rights
to warranty claims.
2.6
Explosion protection
Installation of the pump sets in potentially explosive at-
mospheres shall be governed by the provisions of Direc-
tive 94/9/EU (ATEX 100a).
The motors may be connected to electrical low-voltage grids
with nominal voltages and voltage tolerances to IEC 38 or other
grids or power supply facilities with max. nominal voltage toler-
ances of
"
10 %.
The motor must be protected by an overload protection device.
Motor overload protection can be realized by:
- limiting the current (e.g. by means of a motor protection
switch to EN 60 974-2). In this case, the rated current (see
name plate) must be set. The running motor must be cut out
within 15 minutes after 1.15 times the rated current has been
reached.
- limiting the temperature by means of bimetal switches inte-
grated in the stator. The bimetal switches must be connected
to a tripping unit.
The motors can also be operated on frequency inverters. Make
sure to observe the design data of the motor in this case. To pre-
vent an inadmissible heat build-up in the motor, motors oper-
ated on frequency inverters must always be equipped with bi-
metal switches in the stator.
When reaching the temperature limit stipulated for compliance
with the temperature class, the motor must be cut out by means
of an approved tripping unit (to ATEX 100a) connected to the
measuring points provided.
