Definition of Standard IEC/EN 61800-3: “Adjustable Speed Electrical Power Drives Systems”
Environments:
First Environment:
environments that include domestic installations, as well as establishments directly connected
without intermediate transformer to a low-voltage power supply network which supplies buildings used for domestic
purposes.
Second Environment:
includes all establishments other than those directly connected to a low-voltage power
supply network that supplies buildings used for domestic purposes.
Categories:
Category C1:
inverters with a voltage rating less than 1000 V and intended for use in the First Environment.
Category C2:
inverters with a voltage rating less than 1000 V intended for use in the First Environment, not provided
with a plug connector or movable installations. They must be installed and commissioned by a professional.
Category C3:
inverters with a voltage rating less than 1000 V and intended for use in the Second Environment
only (not designed for use in the First Environment).
✓
NOTE!
A professional is a person or organization familiar with the installation and/or commissioning of
inverters, including their EMC aspects.
3.3.3 Characteristics of the RFI Filter
CFW320 inverters, when installed with external filter, comply with the directive for electromagnetic compatibility
(2014/30/EU). The use of RFI filter kit indicated in the
, or equivalent, is required to reduce the
disturbance conducted from the inverter to the power line in the high frequency band (
>
150 kHz) observing the
maximum conducted emission levels of electromagnetic compatibility standards, such as EN 61800-3.
