6. Feed the twisted pair cables and, if applicable, the power cables through the opening
and through the wall box punch-out holes, securing them with cable clamps to provide
strain relief.
NOTES:
• In order to fit in the wall box, the twisted pair cables and RJ-45 connectors
should not have a boot installed.
• One power supply can power both the transmitter and the receiver, so only
one unit needs a power supply (see Power Supply Wiring on page 11 and
Ground Loops on page 14.
7. Trim back and insulate exposed cable shields with heat shrink to reduce the chance of
short circuits.
To prevent short circuits, the outer foil shield can be cut back to the point where the
cable exits the cable clamp.
8. Connect the cables to the rear of the unit.
9. Connect front panel devices (see Transmitter Front Panel on page 6 and Receiver
Front Panel on page 9 for connector details), restore the power supply, and test the
transmitter and receiver system. Make any cabling adjustments before final installation,
as the cables will be inaccessible afterwards.
