The installation is allowed to be carried out by qualified personnelonly. Further statutory standards, regulations and technical rulings have to betaken into account.All outer circuits, wires and lines connected to the device must have a minimumisolation resistance of 250 V. If the voltage exceeds 42 V DC an isolationresistance with 500 kOhm min. is necessary.The section dimension of the power supply wires or the current loop wires shallmeet the technical requirements of the NivuCompact. For information on deviceprotection see chapter 2.3.Particularly regarding Ex protection measures it must be checked if the unitpower supplies must be integrated into the facility’s emergency shutdownconception.6.2 Transmitter Installation6.2.1 GeneralThe transmitters mounting place has to be selected according to certain criteria.Please strictly avoid:- direct sunlight (use weatherproof cover if necessary)- heat emitting objects (max. ambient temperature: +65° C)- objects with strong electromagnetic fields (e.g. frequency converters)- corrosive chemicals or gas- mechanical shocks- vibrations- radioactive radiation- installation close to footpaths or travel ways- to cross the sonic cone- distances below the minimum distance to max. level (see specificationsChap. 2.3, Measurement Range)Please note during installation that electronic components may be destructedcaused by electrostatic strokes. Due to this make sure to have sufficient earthingdevices in order to avoid too high electrostatic charge.
