To connect the Ethernet cable:
1. Open the communication gland.
CAUTION!
The gland includes a rubber waterproof fitting, which should be used to ensure proper sealing.
2. Remove the rubber fitting from the gland and insert the CAT5/6 cable through the gland and through
the gland opening in the Connection Unit .
3. Remove the plastic seal from the large opening that has a cut in the rubber fitting.
4. Push the cable into the cut opening of the rubber fitting.
CAT5/5E STP cables have eight wires (four twisted pairs), as shown in the diagram below. Wire colors may
differ from one cable to another. You can use either wiring standard, as long as both sides of the cable
have the same pin-out and color-coding.
