Abstract: The invention relates to a cooling arrangement in a frequency converter, the arrangement being configured to convey heat generated at the frequency converter to a space surrounding the frequency converter, comprising a power part (10) of the frequency converter, a control part (20) and cooling means, comprising a cooling motor (31) and a transfer means (32) for producing cooling. In accordance with the invention, a cooling frequency converter is arranged in connection with the frequency converter to control the cooling means. The power part of the cooling frequency converter comprises a rectifier (11) of the frequency converter, an intermediate circuit (12) of the frequency converter as well as a unique power unit (43) of the cooling frequency converter.

Abstract: An arrangement for fastening a capacitor to an electrotechnical device and for protecting the capacitor from stresses caused by the environment. The arrangement includes a disk-like frame, one or more openings pierced in the frame, a capacitor to be fastened to each opening and one or more substantially hollow domed fastening and protection means, inside of which one of the capacitors is arranged, wherein each of the fastening and protection means is arranged into one of the openings in the frame.

Abstract: The present invention relates to a frequency converter comprising a power part and a control and adjustment part. The frequency converter is characterized in that the control and adjustment part is arranged to be a separate control and adjustment unit separated from the power part and in that the control and adjustment unit forming the control and adjustment part is arranged to be connected to the power part by a telecommunication unit. The telecommunication unit is a wired optic connection or a wireless connection, the control and adjustment part and the power part then being galvanically separated.

Abstract: The present invention relates to a grounding arrangement, particularly in connection with a shielded cable. The arrangement comprises clamping means to connect a shield surrounding the cable to a ground potential, the clamping means being arranged to be attached to a base. The arrangement is characterized in that an elongated frame of the clamping means comprise projecting gripping means and an installation element. The base comprises a locking element for receiving the frame equipped with the gripping means and a tightening element for receiving the installation element. The frame of the clamping means is arranged in the locking element and the installation element is turned over the at least partly peeled shielded cable and attached to the tightening element by connecting means.
