Instruction Sheet
Step 1: Prepare enclosure by drilling a 20mm (0.787”) hole in the
enclosure. Install RJ45 housing into enclosure. The rubber gasket should be
on the outside of the enclosure to insure proper sealing.
Step 2: Remove the thin enclosure nut from the feedthru assembly. This
can be discarded. Loosen the compression nut completely.
Step 3: Insert the RJ45 connector thru the feedthru assembly
Step 4: Tighten the compression nut loosely
Step 5: Screw the entire feedthru assembly into the RJ45-ECS housing
which is already mounted in the enclosure. There should be a rubber gasket
between the two assemblies. Tighten the feedthru assembly to create a seal.
Step 6: The final step is to tighten the compression nut until the gaskets are
tight around the Cat5 cable. Always push the cable toward the connector
while tightening to ensure good strain relief of cable to connector
Disassembly
Step 1: Loosen the compression nut to relieve pressure on the Cat5 cable
Step 2: Unscrew the feedthru assembly from the RJ45-ECS housing
Step 3: Using a small screwdriver depress the RJ45 bayonet lock to release
the RJ45 connector from the socket
