Compliance with various system level guidelines:
The harmonic current data in the table are given in accordance with IEC/EN61000-3-12 with reference to the Power Drive Systems product standard. They may
be used as the basis for calculation of the harmonic currents' influence on the power supply system and for the documentation of compliance with relevant
regional guidelines: IEEE 519 -1992; G5/4.
2.9.7 Immunity Requirements
The immunity requirements for frequency converters depend on the environment where they are installed. The requirements for the industrial environment are
higher than the requirements for the home and office environment. All GE frequency converters comply with the requirements for the industrial environment and
consequently comply also with the lower requirements for home and office environment with a large safety margin.
In order to document immunity against electrical interference from electrical phenomena, the following immunity tests have been made on a system consisting
of a frequency converter (with options if relevant), a screened control cable and a control box with potentiometer, motor cable and motor.
The tests were performed in accordance with the following basic standards:
• EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD): Simulation of electrostatic discharges from human beings.
• EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modulated simulation of the effects of radar and radio communi-
cation equipment as well as mobile communications equipment.
• EN 61000-4-4 (IEC 61000-4-4): Burst transients: Simulation of interference brought about by switching a contactor, relay or similar devices.
• EN 61000-4-5 (IEC 61000-4-5): Surge transients: Simulation of transients brought about e.g. by lightning that strikes near installations.
• EN 61000-4-6 (IEC 61000-4-6): RF Common mode: Simulation of the effect from radio-transmission equipment joined by connection cables.
