Glossary
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.

[ðSection2.3,Page9]
2.10 Electromagnetic compatibility (EMC)
2.10.1 Interference emission requirements
The EN61800-3 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:

12 / 96
Table4: Categories of intended use
Category Definition Limits to EN55011
C1 Frequency inverters with a supply voltage under 1000V installed in the first
environment (residential and office areas).
Class B
C2 Frequency inverters with a supply voltage under 1000V installed in the 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.
Class A, Group 1
C3 Frequency inverters with a supply voltage under 1000V installed in the second
environment (industrial environments).
Class A, Group 2
C4 Frequency inverters with a supply voltage over 1000V and a nominal current
over 400A installed in the second environment (industrial environments) or that
are envisaged for use in complex systems.
No borderline/
boundary1)
The following limit values and inspection/test levels must be complied with if the generic
standard on interference emissions applies:
Table5: Classification of installation environment
Environment Generic standard Limits to EN55011
First environment (residential and office areas) EN/IEC61000-6-3
for private, business and commercial
environments
Class B
Second environment (industrial environments) EN/IEC61000-6-4
for industrial environments
Class A, Group 1
The frequency inverter meets the following requirements:

Power
[kW]
Cable length
[m]
Category to EN 61800-3 Limits to EN55011
≤ 11 ≤5 C1 Class B
The EN61800-3 standard requires that the following warning be provided for drive systems
that do not comply with category C1 specifications:
This product can produce high-frequency interference emissions that may necessitate
targeted interference suppression measures in a residential or office environment.
2.10.2 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
for symmetric, three-phase devices (professional devices with a total power of up to
1kW)
– EN 61000-3-12
for devices with a phase current of between 16A and 75A and professional devices
from 1kW up to a phase current of 16 A.
2.10.3 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.
1An EMC plan must be devised.

13 / 96
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

handling noxious, explosive, hot or other hazardous fluids.
3. If the pressure booster system has handled fluids whose residues could lead to
corrosion damage in the presence of atmospheric humidity or could ignite upon contact
with oxygen, the pressure booster system must also be neutralised, and anhydrous inert
gas must be blown through the pressure booster system to ensure drying.
4. Always complete and enclose a certificate of decontamination when returning the
pressure booster system. [ðSection12,Page89]
