User Manual of A90 Series Inverter 3.3.5 Wiring of multi-function output terminals The multi-function output terminal Y1 is powered on by the internal 24V power supply of the inverter or an external power supply, as shown in Fig. 3-14: a: Use of internal power supply b: Use of external power supply Fig. 3-14 Wiring of Multi-function Output Terminals Note: (1) An anti-parallel diode must be included in the relay wire package. The absorption circuit components should be installed at both ends of the coil of the relay or contactor. (2) For the A90-4T017B model and below, the terminals COM and GND should be connected internally.
3.3.6 Wiring of analog output terminals The analog output terminals (M1 and M2) are connected with external analog meters to represent physical quantities. The dial switch is set to the output current mode (0-20mA) or (0-10V). M1 corresponds to S3, and M2 corresponds to S4 (for the inverter of 90KW and power, M1 corresponds to S2, and M2 corresponds to S3). M1 only outputs the voltage (0-10V). Wiring of the dial switch and terminals is as follows: S4/S3 41 M1 Inverter M2 V S3/S2 M2 is for analog voltage output M2 is for analog current output V I M2 is for analog voltage output
