Basic application wiring: 4~20mA control signal input positive to terminal 2 Al1, negative to terminal
4 GND. start terminals 10 and 12 have been factory connected, default power on start.
lf you need to install a starting switch on the control cabinet, you can make 10 and 12 as a switch.
Safety reminder: it is recommended to use the alarm output function of the power conditioner when
designing the electrical wiring, the power conditioner for the load and power supply has a perfect
alarm function, when there is any abnormality, it can be the first time alarm output.
