While it may seem simple, please consult a licensed electrician to come do the replacement. Below are the steps they would follow to complete the replacement.
To wire a Nuvo’s Intention pendant light, an electrician would first need to insert the green grounding screw into the hole with two raised dimples.
Then, they will wrap the ground wire from the fixture around the green grounding screw and connect it to the ground wire from the outlet box.
Next, they will wire certain wires to a black or white power source. Once they have completed putting the wires together, the electrician will connect the fixture wires to the wall wires and the wire installation will be complete.
