Conformal Installation; Emission And Immunity Levels - WEG CFW700 Manual Del Usuario

Installation and Connection

3.3.1 Conformal Installation

1) Inverters with built-in C3 RFI filter CFW700...C3...
2) Sizes A to D inverters with built-in C3 RFI filter capacitors grounding screws and size E with
J1 cable in the position (XE1). For more information see
3) Shielded output cables (motor cables) and connect the shield at both ends (motor and
inverter) with a low impedance connection for high frequency. Use PCSx-01 kit supplied
with sizes A, B and C inverters. For sizes D and E inverters use the clamps supplied with
the product. Ensure good contact between the cable shield and the clamps. Refer to
3.4 and keep the proper separation from other cables according to
Distances. The maximum motor cable length and conduction and radiated emission levels
are presented at table
to have a lower emission level and/or a longer motor cable length. For more information (RFI
filter commercial reference, motor cable length and emission levels) refer to
4) Shielded control cables and separate the remaining cables according to
Distances.
5) Inverter grounding according to the instructions on item
6) Grounded power supply.

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
Surge Immunity

Refer to table B.5 for conducted and radiated emission levels accomplished with and without
external RFI filter. The reference model for the external filter is also presented.
