Radio-Frequency Interference (RFI) issues can affect electrical devices sharing the same or close proximity electrical networks, and can manifest themselves in a multitude of ways.

Typically, the BMCS is the first item that suffers from communications issues. However, medical facilities may have sensitive imaging equipment or life critical systems which could be particularly sensitive to RFI.  Multi tenant buildings can also have a multitude of sensitive / business critical electrical equipment such as financial servers.

Locating the source, cause and best method of retroactive mitigation techniques can become very costly.

Controlstore has allowed for VSDs that comply with the highest level of RFI compliance under the current Australian standard AS61800-3 which is C1. One of the key differences between a C1 and a C2 product installation is the requirements of an “EMC Expert”.

C1 has no requirement to have an EMC Expert as the onus for RFI compliance is on the product and documenting how to install it. However, with C2 (supplied by other brands), according to AS61800-3 requires that installation and commissioning is carried out by an ‘EMC expert’ to ensure the entire system meets harmonics requirements.

Also, there is a huge difference is the level of noise emitted with drives that have C1 filter is much lower compared to the ones with C2 filter.  For more info about the difference in noise levels between the C1 and C2 click here.
