AC Power
The AC adapter easily connects to the device. The AC rating of the adapter accepts most standard
voltages and frequencies worldwide. Refer to the input voltage requirements stated on the label affixed
to the adapter to ensure that the adapter can be used with the AC mains supply.
The AC plug outlet provided with the adapter may need to be replaced to match the country
configuration. The adapter cable uses a standard connector for this cable for use of a pre-wired cable
appropriate to the outlet configuration. If the appropriate cable is not available, the existing AC plug
end can be severed and a replacement plug affixed. Consult a qualified electrician for this activity.
Do not plug the adapter into the mains power. First, verify that the RF connector is properly terminated
(see Power
), and then plug in the radio-side connector from the AC adapter to the radio. If the AC mains
can be turned off using a switch, disable the power, plug the AC side of the adapter into the AC mains
socket, and then enable power to the circuit. If the AC mains cannot be turned off, plug in to the AC
main socket to apply power.
Verify that the radio is active by observing LED activity. All LEDs on the radio flash at initial power
cycle.
It is strongly encouraged that the AC mains supply be fused or on a separate breaker to ensure against
over-voltage and/or over-current situations and to provide some form of protection to the radio
electronics and other devices connected to the same supply. In addition, if the AC power is 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.
DC Power
The device accepts DC power within the voltage specifications. For some EX-2.4i terminals, the DC
voltage is 48 volts, nominal. For all other i-Series models, the DC voltage input accepts either 24 volts
or 48 volts, nominal. Ensure that the power source is specified for the proper amount of current delivery
capacity. The DC power may be connected as a positive or negative voltage supply, and be referenced
to ground or ‘floating’ (differential voltage). There are different system grounding considerations
depending on the nature of the DC supply grounding, and consult a qualified electrician or telecoms
professional on the proper wiring and grounding process.
