Installation Guide for the 330907-05-30-70-12-CN

Follow these steps for a proper installation of the 330907-05-30-70-12-CN.

Step 1: Mounting Hole Preparation

Firstly, prepare a mounting hole with M10X1 threads. Ensure the hole depth accommodates at least 15 mm of thread engagement. Then, clean the threads thoroughly to remove any debris. Consequently, the 330907-05-30-70-12-CN will install smoothly without cross-threading.

Step 3: FluidLoc Cable Handling

Then, handle the FluidLoc cable with care during routing. The 12 connector option includes special sealing that prevents oil leakage. Do not kink or crush the cable, as this may compromise the FluidLoc sealing. Consequently, the cable will maintain its fluid containment properties.

Step 4: Cable Connection

Furthermore, connect the 330907-05-30-70-12-CN to your extension cable. Use the miniature coaxial ClickLoc connector for this connection. Push firmly until the connector locks into place with an audible click. Consequently, the connection will resist loosening from vibration.
