Grabbing the Acc from the fuse panel is fine, just be sure to grab the protected side of the fuse so your Acc lead is protected from shorts too. Don't want to run a screw through the lead and smoke something further up the line.
Opus (and many forum members, including myself) do not reccomned taping the fuse panel for the main power lead of the Opus. The Opus documentation recommends main power be taken directly off the battery. One of those "Best Practice" things.
Oh, yeah, don't forget to fuse the main power lead CLOSE to the battery. 6 inches or less is a good rule of thumb. (10 amp for the Opus 90, 15 for the 150).
