It might also work under an open pipe rack or inside a wet pump station. In these places, water and dirt can easily damage internal electrical parts. Because of this risk, buyers frequently request an IP68 electric actuator. However, this rating by itself fails to show the maximum submersion depth. It also leaves out the allowed time underwater.
