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. (
ð Section 2.2, Page 8)
2.9 Electromagnetic compatibility (EMC)
2.9.1 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:
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/
boundary
1)
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:

≤ 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.
1) An EMC plan must be devised.
