present, replace the O-ring.
When replacing the O-ring,
first clean the O-ring
surface inside the housing and the O-ring groove in the end cap using a lint-
free cloth or paper towel, and then apply a
light coat of silicone grease to the
O-ring before installing it.
2.
Insert the chassis into the housing and align the locator pin in the end cap with the
slot in the housing.
3. Push the connector end cap into the housing until it is fully seated.
