Incorrect wiring can damage the sensor and void the warranty! Before applying power, make sure all connections are correct and secure!
The following figure illustrates how to remove the terminal block.
Figure 16: Removing the Terminal Block
The electronics box has two compression fittings to provide water sealing for the fiber optics cable and the electronics cable. The compression fitting must be tightened with a wrench around the cables to achieve water sealing. To achieve sealing for the fiber optics cable, hand tighten the compression fitting around the cable, and then use a wrench to tighten another 1 1/2 to 2 turns. If the cable is too thin then it may be necessary to add a bushing or heat shrink material to increase the cable diameter in order to ensure sealing. Hand tighten the compression fitting around the cable, and then use a wrench to tighten another 1½ to 2 turns.
