1 Type RF Filters Solve Noise Problems MT orporation type RF filters offer an economical solution to many facility interference problems caused by the high frequency emissions of adjustable speed motor drives and inverters. Type RF filters can prevent drives and inverters from interfering with other sensitive electronic loads by reducing both common mode and differential mode noise emissions. Typical drive and inverter applications include: Motor rives Motor rives Uninterruptible Power Supplies ctive Harmonic Filters attery hargers / lectronic Welders Help Meet M irective The RF series of filters are specially designed to provide sufficient attenuation of the conducted RFI and MI associated with adjustable speed drive and inverter applications. Usually, drive and inverter systems using these filters will be able to meet the stringent requirements of the M irectives (lass ) and the F limits for conducted noise emissions. ctual testing may be necessary to verify system compliance. Touch Safe onstruction In compliance with international safety standards, and in conformance with the low voltage directive, type RF filters are supplied as standard with touch safe terminations on all units rated through 1 amps.

6 ROMMN INSTLLTION PRTIS Filter onnection Our type RF2 and RF3 filters are intended for use at the input side of an adjustable speed drive or inverter. o not attempt to use these on the output (load side) of an inverter or drive. ood wiring practices will minimize RFI problems. Route all conductors as close to the panel as possible Physically separate the filter input and output conductors Keep drive input and output leads separated lways keep power and control wiring separated Use shielded wiring where possible Use single point grounding (connect system ground to filter) FILTR LIN RIV MOTOR onnect the incoming power conductors to the Line side terminals of the filter. onnect the Load side terminals to the line reactor or drive input terminals. Note that the ground termination may also be designated by or N. Keep all wiring as close as possible to the grounded panel (ground plane). Filter Mounting onnect the power system ground (earth connection) directly to the filter ground (earth) termination prior to connecting any other wires. Filter grounding is required to assure safety and desired filter performance. For the best ground connection, use a multi stranded copper conductor or copper strap. Mount the filter as close as possible to the RFI/MI source (drive, inverter, UPS, etc.). For best performance, mount filter directly to a bare metal grounded panel. Use shielded conductors to minimize radiated high frequency noise levels. urrent Ratings The RF series filters are rated in True RMS (trms) amperes. Harmonic current distortion will increase the trms T1 T2 T3 current of a system above the fundamental current (typically motor FL) of the connected loads. Line reactors (3% or 5% impedance) are useful in reducing harmonic current distortion and the trms current. If minimum 3% impedance line reactors are included in the installation, then the trms amperes will be lower and the filter can be sized for the reduced load current. If you know the trms amperes of the load to be connected to the filter, then select the filter directly from the RMS amperes selection tables. If you are not sure of the trms amperes, you can select the filters based on the horsepower (or KW) rating of the load to be connected. etermine if a reactor (minimum 3% impedance) will be used in addition to the RFI filter and select accordingly. Parallel onnection for Higher Ratings Type RF filters may be connected in parallel to achieve higher current ratings provided that identical models are used, and the connection allows each individual filter to share current equally. The use of two separate distribution (terminal) blocks will make this easier. erate each filter by % when ever connecting in a parallel configuration and always follow the N or local electrical codes. Make ground connections first, then for each filter to be parallel connected, precut three leads, of equal wire type and gauge, to the same exact length. Using these leads, connect the filter input terminals,, and to the respective terminal on a separate distribution block. Repeat this procedure for the output terminals.
