Abstract: The present invention comprises a fish guidance rack (2) for use in a fish guidance system in a watercourse (W) at a run-of-river hydropower plant or a water intake. The rack comprises a series of vertical bars (1) mounted on a rack frame (7) along a longitudinal axis (L) of the rack between a first end (5) of the rack and a second end (6) of the rack. The rack comprises bars with a hydrodynamic curved form, and a generally increasing inter-bar spacing (sb) in the downstream direction.

Abstract: An outlet modular enclosure (OME) is configured to receive a compatible Snap-In/Snap-Out (SISO) outlet unit. The outlet modular enclosure includes an electrically conductive housing with a first aperture sized to receive the outlet unit and a second aperture sized to receive a wire harness. The electrically conductive housing forms at least a portion of a Faraday cage around the outlet unit. The modular unit (MOU) assembly includes the OME and a compatible Snap-In/Snap-Out (SISO) OU with a front side faceplate. The opposing rear side of the SISO is receivable within the first aperture of the OME, while a wire harness adapted to deliver power and data to the OU is received by the second aperture. The wire harness has an electrically conductive shield overbraid at a first end thereof that is electrically connectable to the outlet modular housing.
