Note: After configuring the LTE7490, turn WiFi off.
Step 7 Grounding
Secure a green/yellow ground cable (18 AWG or smaller) to the LTE7490’s rear panel using the M4 ground screw.
Attach the other end of the cable to the ground, either to the same ground electrode as the pole you installed the device on or to the main grounding electrode of the building.
Follow your country’s regulations and safety instructions to electrically ground the device properly. Qualified service personnel must confirm that the building’s protective earthing
terminal is valid.
