Signal and Power Input Connections 77.1 INTRODUCTIONThe following describes how to connect your sensors to your meter with andwithout sensor excitation and how to connect the AC power to your meter.Prior to wiring the sensor to the meter, check with a multimeter that a properexcitation exists.WARNING: Do not connect ac power to your meter until you havecompleted all input and output connections. Failure to do so may result ininjury! This device must only be installed electrically by specially trainedelectrician with corresponding qualifications.7.2 SIGNAL INPUT CONNECTIONSThe following figures (7-1 through 7-5) show the connections for voltage,current and potentiometer inputs:(4-20mA)(+)(-) + -NC+S–S123P9METERNCNCNC123P3Figure 7-1.
