Emission And Immunity Levels - WEG CFW300 Manual Del Usuario

Installation and Connection
4. Grounded power supply.
5. Use short wiring to ground the external filter or inverter.
6. Ground the mounting plate using a flexible braid as short as possible. Flat conductors have
lower impedance at high frequencies.
7. Use cord grips for strain relief on conduits.

3.3.2 Emission and Immunity Levels

EMC Phenomenon
Emission:
Mains Terminal Disturbance Voltage
Frequency range: 150 kHz to 30 MHz
Electromagnetic Radiation Disturbance
Frequency range: 30 MHz to 1000 MHz
Immunity:
Electrostatic Discharge (ESD)
Fast Transient-Burst
Conducted Radio-Frequency Common
Mode
Surges
Radio-Frequency Electromagnetic Field
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).
