There's a black cord running from the opener to the ceiling outlet, as well as a thin brown cable running to a brown box thats plugged into the same outlet, but also bolted/screwed in to the outlet.
I would guess this is common, though I'm changing the battery and don't know if I need to unplug both the brown box and the black cord, or just the black? Is there anything else I need to unplug before changing the battery? Thank you for any info.
