Abstract
Abstract An add-on module for a variable speed drive includes a casing containing an electronic circuit and a connector to plug into a corresponding connector on the variable speed drive. The casing is generally L-shaped with a front portion carrying the connector and positioned along the front of the variable speed drive and a side portion accommodated on one side of the variable speed drive. The electronic circuit includes front and side printed circuit boards electrically connected to each other and the angle between which is substantially equal to the angle between the two portions of the casing.
