Contact configuration

1. Always apply grease before mating

2. Pull out, pull straight out, do not twist around

3. Do not pull on the cable and avoid sharp bends at cable entry

4. When using a bulkhead connector, ensure that there are no angular loads

5. All kinds of connectors should not be exposed to extended periods of heat or direct sunlight

Greasing and mating above water (dry mate)

1. Connectors must be greased with Molykote 44 Medium (recommended brand) before every mating

2. A layer of grease corresponding to minimum 1/3 of socket depth should be applied to the female connector

3. The inner edge of all sockets should be completely covered, and a thin transparent layer of grease left visible on the face of the connector

4. After greasing, fully mate the male and female connector in order to secure optimal distribution of grease on pins and in sockets

5. To confirm that grease has been sufficiently applied, de-mate and check for grease on every male pin. Then re-mate the connector
