Physical Installation Guide for how to properly install the Milesight CT305, set this up within the app, and the reporting requirements for the device to work.
Physical Installation Guide:
1. Device Assembly
Plug the CT clips into each of the corresponding locations on the Blue Transformer device. The CTs can be connected to the connectors of transceiver without any specific order matching
requirement.
2. Antenna Installation
Rotate the antenna into the antenna connector. The antenna should be installed vertically and
kept away from metal objects and obstacles.
Screw the antenna clockwise onto the port until secure, and position the antenna vertically to optimize LoRaWAN signal strength.
Note: Keep the device away from metal objects, obstacles, or the environment surrounded by
other electrical equipment that may cause interference. If necessary, please select a magnetic
antenna.
3. Transformer Installation
Open the current transformer to clip it around a single-phase wire. Then close the clip with a
slight “click” sound to make sure the clip firmly grips the wire.
Do not place Phase wire and Neutral wire within a single current transformer.
Please make sure that you at least connect a Phase A CT to phase A wire, otherwise the device will be powered off.
4. Transceiver Installation
The transceiver can be put or hang in any suitable position or to be fixed via cable-ties.
