27 Commander SE User Guide
www.controltechniques.com Issue Number 8
Commander SE sizes 3, 4 and 5 drives include DC chokes, AC reactors are only
required for harmonic reduction.
*These input reactors are not stocked by Control Techniques. Therefore they
should be ordered directly from the manufacturer, Skot Transformers, or sourced
locally.

They can be ordered using the above part numbers or Skot reference numbers:
4400-0240 = 35232
4400-0241 = 35233
Line reactors also improve the input current waveform and reduce the input current
harmonic levels. Further information is included in the EMC Data sheet which is
available from Control Techniques’ Drive Centres or Distributors.
4.4.5 Input line reactors for Harmonics standards EN61000-3-2 & IEC61000-3-2
The following input line reactors allow the Commander SE 0.25 - 0.55kW drives to
conform to harmonic standards EN61000-3-2 and IEC61000-3-2
EN61000-3-2 and IEC61000-3-2 applies to equipment with a supply voltage of 230Vac
and a line current up to 16A, single or three phase. Professional equipment with rated
input power exceeding 1kW has no limits - this applies to the 0.75kW drive.
Further information on EN61000-3-2 and IEC61000-3-2 is included on the EMC data
sheets available from your local Control Techniques Drive Centre or distributor.
4.4.6 Voltage fluctuation (Flicker) standard EN61000-3-3 (IEC61000-3-3)
Those models which fall within the scope of EN61000-3-3, as stated in the Declaration
of Conformity, conform to the requirements for manual switching, i.e. the voltage dip
caused when a drive at room temperature is switched on is within the permitted limits.
The drive does not of itself cause periodic voltage fluctuation in normal operation. The
installer must ensure that the control of the drive is such that periodic fluctuations in
supply current do not infringe the flicker requirements where applicable. Note that large
periodic load fluctuations in the frequency range of between 1Hz and 30Hz are
particularly inclined to cause irritating lighting flicker and are subject to stringent limits
under EN61000-3-3.
4.5 Electromagnetic compatibility (EMC)
This section gives installation guidelines for ensuring electromagnetic compatibility.
Further detailed information is provided in the EMC Data sheets which are available
from Control Techniques’ Drive Centres or distributors.
The drive meets the standards for electromagnetic immunity stated in section 3.2
without any special installation precautions. To prevent possible nuisance tripping, it is
recommended that all inductive circuits associated with the drive, for example relay
coils, electromagnetic brakes etc. should be fitted with appropriate suppression.
The following precautions should be taken to prevent the drive from causing
interference with other electronic equipment.
For general use the guidelines in section 4.5.1 Routine EMC precautions should be
followed. These are sufficient to prevent interference to general purpose industrial and
similar equipment of good quality recent design.
