a) Mains suppression filter
To achieve full functionality of the filter you must fix it to a bright and well
earthed mounting plate, paying attention to having good contact at both sides.
The screen (earth) is to be connected to the special labelled screw terminal on
the filter.
b) Mains transformer
The transformer is to be fixed to the mounting plate, too. Contacting has to be
performed with as large a surface area as possible (remove a possibly existing
coat of lacquer). Additionally, earth the transformer via a short cable (≥ 2.5
mm2) to the mounting plate using the twin blade terminal (6.3 mm) on the
transformer.
Connect the mains earth wire resp. the screen of the mains cable coming from
the filter to the ‘PE’ labelled terminal.
Connect the screen of the Controller supply to the twin blade terminal on the
transformer.
c) Controller
Each inserted module is earthed via a special contact socket in the upper
metal angle (metal frame with
devices) at the back of the Controller.
Connect
