Even with friendly fire turned off these effects can still hit players. The Sledge turret can be used directly by holding it and using it on another player. This actually causes a few other bugs as a result. The Stun Baton's repulsor effect does the same but you can't hit a player directly. Instead they have to be standing either near you or a zombie you're hitting when you hit something for it to go off. The second one in particular has pretty much completely stopped the ability for me to participate in a melee fight with my buddy in co op. In some cases it's really bad such as knocking him off the roof of a skyscraper POI despite him standing behind me while I was meleeing zombies. In other cases this can actually cause someone to ragdoll inside of blocks like when I stunned him in our horde base and he got trapped in the wall.
