7.3 APPLYING SILICONE DIELECTRIC COMPOUND TO AMP CONNECTORS
Silicone Dielectric Compound must be used on the AMP connections for the following reasons:
• To prevent oxidation at the mechanical joint between male and female pins.
• To prevent electrical malfunction caused by low level conductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric Compound to the electrical connectors.
1. To prevent oxidation and low level conductivity, silicone dielectric grease must be packed completely around male and
female pins on the inside of the connector after the mating of the housing to the header. This is easily achieved by
using a syringe to fill the header with silicone dielectric compound, to a point just above the top of the male pins inside
the header. When assembling the housing to the header, it is possible that the housing will become air locked, thus
preventing the housing latch from engaging.
2. Pierce one of the unused wire seals to allow the trapped air inside the housing to escape.
3. Install a hole plug into this and/or any unused wire seal that has silicone dielectric compound escaping from it.
