5.7 Mechanical preparation of a common cable entry cubicle
Some filters are equipped with a common cable entry cubicle. This optional cubicle
(WxDxH = 600 x 600 x 2150 mm excluding base frame) may act as a single top or bottom
cable entry point for the active filter. This cubicle contains a bus bar system to which the
supply cables have to be connected and which distributes the power to the power units
