Accumulator
Pressure losses may occur in the piping
downstream of the pressure booster system as a
result of losses due to leakage. The accumulator
serves to compensate for pressure losses and
minimises the frequency of starts of the pressure
booster system.
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Dry running protection
Dry running protection devices prevent the pump
from being operated without the fluid to be
handled, which would result in pump damage.
Switchgear and controlgear assembly
Control cabinet with one or several control units/
switchgears and electrical equipment.

2.8 Unauthorised modes of operation
Always observe the limits stated in the product literature.
The warranty relating to the operating reliability and safety of the pressure booster
system supplied is only valid if the equipment is used in accordance with its intended
use. (ðSection2.2,Page8)
2.9 Electromagnetic compatibility (EMC)
2.9.1 Interference emission requirements
The EN61800-3 EMC product standard is relevant for electric variable speed drives/
control systems. It specifies all pertinent requirements and refers to the relevant
generic standards for complying with the EMC Directive.
Frequency inverters are commonly used by operators as a part of a system, plant or
machine assembly. It should be noted that the operator bears all responsibility for
the final EMC properties of the equipment, plant or installation.
A prerequisite or requirement for complying with the relevant standards or the limit
values and inspection/test levels referenced by them is that all information and
descriptions regarding EMC-compliant installation be observed and followed.
In accordance with the EMC product standard, the EMC requirements to be met
depend on the purpose or intended use of the frequency inverter. Four categories
are defined in the EMC product standard:
Table4: Categories of intended use
Category Definition Limits to EN55011
C1 Frequency inverters with a supply voltage under 1000V installed in the
Class B
first environment (residential and office areas).
C2 Frequency inverters with a supply voltage under 1000V installed in the
Class A, Group 1
first environment (residential and office areas) that are neither ready to
be plugged in/connected nor are mobile and must be installed and
commissioned by specialist personnel.
C3 Frequency inverters with a supply voltage under 1000V installed in the
Class A, Group 2
second environment (industrial environments).
C4 Frequency inverters with a supply voltage over 1000V and a nominal
current over 400A installed in the second environment (industrial
No borderline/
boundary
environments) or that are envisaged for use in complex systems.
The following limit values and inspection/test levels must be complied with if the
generic standard on interference emissions applies:
1)
1) An EMC plan must be devised.

This product can produce high-frequency interference emissions that may necessitate
targeted interference suppression measures in a residential or office environment.
2.9.2 Line harmonics requirements
The product is a device for professional applications as defined by EN 61000-3-2. The
following generic standards apply when establishing a connection to the public
power grid:
▪ EN 61000-3-2
▪ EN 61000-3-12

2.9.3 Interference immunity requirements
In general, the interference immunity requirements for a frequency inverter hinge on
the specific environment in which the inverter is installed.
The requirements for industrial environments are therefore higher than those for
residential and office environments.
The frequency inverter is designed such that the immunity requirements for
industrial environments and, thus, the lower-level requirements for residential and
office environments, are met and fulfilled.
The following relevant generic standards are used for the interference immunity test:
▪ EN 61000-4-2: Electromagnetic compatibility (EMC)
– Part 4-2: Testing and measurement techniques – Electrostatic discharge
immunity test
▪ EN 61000-4-3: Electromagnetic compatibility (EMC)
– Part 4-3: Testing and measurement techniques – Radiated, radio-frequency,
electromagnetic field immunity test
▪ EN 61000-4-4: Electromagnetic compatibility (EMC)
– Part 4-4: Testing and measurement techniques – Electrical fast transient/burst
immunity test
▪ EN 61000-4-5: Electromagnetic compatibility (EMC)
– Part 4-5: Testing and measurement techniques – Surge immunity test
▪ EN 61000-4-6: Electromagnetic compatibility (EMC)
– Part 4-6: Testing and measurement techniques – Immunity to conducted
disturbances, induced by radio-frequency fields

KSB Delta Solo
4 Description
Function The pump (2) is controlled and monitored by a motor-mounted frequency inverter.
As the demand increases or decreases, the pump is started and stopped
automatically.
The standard setting is for the pressure booster system to start automatically as a
function of pressure; the actual pressure is measured by an analog pressure
measuring device (pressure transmitter).
As long as the pressure booster system is in operation, the pump is started and
stopped as a function of demand (standard setting). In this way it is ensured that the
pump operates only in line with actual demand.
The use of this variable speed pump reduces wear as well as the frequency of pump
starts. A fault is output, which can be reported via volt-free contacts (e.g. to the
control station).
If the demand drops towards 0, the pressure booster system slowly runs down to the
stop point.
The pressure booster system is designed with integrated electronic dry running
protection.
A digital lack-of-water display can be connected at the corresponding contacts.
During commissioning and after every power failure, the pressure booster system fills
the piping system slowly to prevent any damage to the piping by surge pressure.
If the pump has not been in operation for 24 hours, a test run is initiated.
