LEROY SOMER SP 2,5 T

BRAND : LEROY SOMER

It is recommended that the internal EMC filter be kept in place unless there is a specific reason for removing it. If the drive is part of a regen system or is a Unidrive SP size 3 to 6 on an IT supply then the internal EMC filter must be removed. The internal EMC filter reduces radio-frequency emission into the line power supply. Where the motor cable is short, it permits the requirements of EN61800-3:2004 to be met for the second environment - for further information see the Unidrive SP User Guide. For longer motor cables the filter continues to provide a useful reduction in emission level, and when used with any length of shielded motor cable up to the limit for the drive, it is unlikely that nearby industrial equipment will be disturbed. It is recommended that the filter be used in all applications unless the ground leakage current (on 400V, 50Hz supply) of 28mA for sizes 0 to 3 and 56mA for sizes 4 to 6 is unacceptable or the above conditions are true.
