Powering 4-20mA sensor with 4-20mA Current Loop Receiver

Hi! I was wondering if anyone could provide me with more information on powering / reading results from a two wire sensor with this product: https://store.ncd.io/product/industrial-iot-long-range-wireless-4-20ma-current-loop-receiver/. Unfortunately, my electrical engineering background is a bit lacking.

My main question is: where should I affix the two wires on the NCD device to the corresponding wires on the sensor? And do I need to solder them together? And information would be super appreciated. Thank you!

This product will work with 2 wire sensors.
The wiring diagram can be found on product page under resources.
