stainless steel box and sealed with a silicone potting compound. Although power does not pass through the isolator, data is passed through by using optical components in the internal circuit. The cable coming from the red painted end of the isolator always connects to the PMC-R A1 Bidi port which is on the bottom row of connectors on the same end as the red Quickstop button. If the isolator is installed backwards, there will be a broken network at this location.
SKK24 Hose Cable The SKK-24 Hose Cable is a mine-duty cable constructed with an armored hose conduit, internal wiring, and a four-wire connector on each end. A brass staple-lock fitting is used to mechanically secure the connection; the brass ends allow approximately 355 degrees of rotation. This cable is used to connect all pressure and stroke sensors to the PMC-R and for the “Bidi” connection between PMC-Rs.
If the system was delivered with yellow shield-to-shield cables then these must be used for the shield-to-shield connection to maintain MSHA compliance!
