1. Corrosion Precautions Rinse the MicroCAT with fresh water after use and prior to storage All exposed metal is titanium other materials are plastic No corrosion precautions are required but avoid direct electrical connection of the MicroCAT housing to mooring or other dissimilar metal hardware Connector Mating and Maintenance Note See Application Note 57 Connector Care and Cable Installation CAUTIONS e Do not use WD 40 or other petroleum based lubricants as they will damage the connectors e For wet pluggable MCBH connectors Silicone lubricants in a spray can may contain ketones esters ethers alcohols or glycols in their propellant Do not use these sprays as they will damage the connector I O cable Clean and inspect the connectors and cable before every deployment and as part of your yearly equipment maintenance Inspect connectors that are unmated for signs of corrosion product around the pins and for cuts nicks or other flaws that may compromise the seal When remating 1 Lightly lubricate the inside of the cable connector with silicone grease DC 4 or equivalent 2 XSG Connector Install the cable connector aligning the raised bump on the side of the cable connector with the large pin pin 1 ground on the MicroCAT Remove any trapped air by burping or gently squeezing the connector near the top and moving your fingers toward the end cap OR MCBH Connector Install the cable con
