Han-Power S with the proven Han Q 8/0 connectors is equipped with single or double distribution. The components for energy transmission and distribution make decentrali-zation within IP 65 and IP 67 areas possible. The Han Q 8/0 connector is well-known and used for standard motor control units in the automation technology area. The use of the new Han Q 4/2 connectors is also possible with frequency converters. As frequency converters never work without having a return voltage within the primary circle, the use of non-contact power contacts is required. The use of the Han Q 4/2 “finger safe” connector in the Han-Power S fulfils these requirements and makes it possible to use connectors on frequency converters under consideration of all of the relevant safety measures.
