subject to significant spikes or variation, power conditioning is a worthwhile investment, as the
quality of mains power may have a direct impact on the device operation, performance and/or
reliability. An Uninterruptible Power Source (UPS) or other form of battery-backed system
protects against brown-out and black-out conditions, and condition the power presented to the
adapter.
Evaluate the opportunity for lightning or other similar surges to be present on the powering
system, including the ability for surges to couple to the power wiring system. If an evaluation
indicates that there is a potential likelihood for these conditions to occur, additional surge
protection is recommended for the input power wiring, especially to protect the radio electronics
between the adapter and the radio’s DC input connector.
The above statement is similarly true for every wired connection to the device. While the
configuration for surge suppression or line conditioning is of a different type for each kind of
signal interface, the opportunity for damage to the device, loss of communications and property
is significant. In some cases, there can also be a risk to human life by not protecting against
lightning entering a building through wiring or improper grounding. If you do not have
experience in this type of installation practice, consult a qualified electrician and/or telecoms
professional during the installation and wiring of the equipment.
Power Injector
The r-Series uses a power injector to send DC power to the radio over the CAT5 cable, and
including the Ethernet connections. Figure 9 shows the power injector connectors that connect
the AC adapter (included with the system) and the radio.

Power injector connectors
Connect the network Ethernet connection to the DATA connection of the power injector.
Connect the cable for the radio to the DATA+POWER connection of the power injector.
Ground the power injector using the grounding receptacle. The injector can also be mounted to a
wall using the bottom panel brackets. For proper safety, the ground source should be the same as
that used for AC power ground into the included AC adapter.
