Page 2: General Precautions
1. General Precautions The system must be used only in accordance with the required protection level. The sensor must be protected against accidental knocks and used in accordance with the instrument’s ambient characteristics and per- formance levels. Sensors must be powered with non distributed networks. For outdoor installations or with cables longer than 30 m*, proceed as indicated at paragraph 3. - Page 3 Electrical connections RATIOMETRIC AND VOLTAGE AMPLIFIED OUTPUT POWER SUPPLY Black White OUTPUT CURRENT AMPLIFIED OUTPUT – mod. E POWER SUPPLY SIGNAL Black Interfaces with SRP/CS and voltage devices The interface with SRP/CS (Safety Related Part of a Control System) is made by mean of multipolar connectors showed on pictures below, where the connections are specified in case of amplified voltage output (3 wire) or current output (2 wire system, the sensor is connected in series with the current loop).
