Power Connector Wiring
CAUTION : The two power cord wires must be kept separate while the power
supply is plugged in. Remove power before wiring.
NOTES:
• If the transmitter and receiver are either older generation units or jumper
configured to the stereo audio position (compatible with the older units), only a
single device needs to be powered in a two-unit system (see “
Signal Jumpers
for Generational Compatibility ” on page 3). The device connected to the
power supply, in turn, provides power to its counterpart. This remote power
application is only available in stereo mode, not mono mode.
•
If the transmitter and receiver are separated by more than 200 feet (61 meters)
of STP/UTP/FTP cable, connect a power supply to both units.
• Do not tin the stripped power supply leads before installing the captive screw
or direct insertion connector. Tinned wires could be pulled out because they are
not as secure in the captive screw and direct insertion connectors.
