Power
The Repeater is powered from an AC or DC power source
depending on the model chosen.
AC power requirements are 120/240 Vac, 50/60 Hz,
15 W. The power cord connection to the Repeater is
a standard IEC 320 plug. Different types of power
cords can be used to adapt to various power
sources.
DC power requirement is 24Vdc, 15W. It is important to
note that the CBR-2DC is considered to have a perma-
nent connection to the power supply. A readily accessi-
ble disconnect device is required between the power
connections on the Repeater and its power source. This
shall be provided during the installation of the unit in a
manner to comply with local electrical regulations. The
power wiring should also be protected from electrical
surge.
Installation
The Repeater is connected to segments of the Carrierband
network like any other station through a drop cable and a
tap. The following should be considered when installing a
Repeater:
The Repeater should be installed in accordance with the
hazardous area control drawing on the last page of these
installation instructions.
Place the Repeater where its indicator lights can be seen.
This will help identify and isolate network problems if
they occur.
While the Repeater is fully enclosed, it is not waterproof.
Install the Repeater in a dry place.
The Repeater operates at temperatures
between -20 and +65 degrees Centigrade
(-4 to 150 degrees F). However, do not install
the Repeater in places where it will be heated
by other equipment or where there is no airflow.
No special requirements for mounting. 19” rack mount-
ing kits for Repeaters are available:
CBR-A0050A Single
CBR-A0060A Double
For guidance on Carrierband networks and Industrial fiber
optics, see Relcom's “Carrierband Network Handbook” and
“Guide to Industrial Fiber Optics” on our website:
www.relcominc.com.
More detailed operational information for the repeaters is
available on our website in document 500-375.
Grounding
Both F-connectors are grounded to the Repeater’s
case to reduce RFI emissions.
On AC powered Repeaters the case is connected
to the mains ground and to the ground stud.
On DC powered Repeaters the case is
connected to the ground terminal and ground stud.
Attach a ground wire from the ground stud to the
grounding facilities provided in the building. Use a
grounding wire that has a current carrying capacity
equal or greater than that of the drop cable outer
conductor.
Front Panel Connectors
Test: F-type (Normally not connected. See manual
for information.)
A: F-type (connected to an IEEE-802.4 tap drop port).
(torque to 35 in-lbs.)
B: ST-type front panel fiber-optic connectors.
Note: OEM models have the power and ground con-
nections on the front of the unit.
DC Models:
WARNING: FOR PERMANENTLY CONNECTED EQUIP-
MENT, A READILY ACCESSIBLE DISCONNECT DEVICE
SHALL BE INCORPORATED IN THE FIXED WIRING.
AVERTISSEMENT: POUR LES ÉQUIPEMENTS RACCOR-
DÉS EN PERMANENCE, UN DISPOSITIF DE DÉCONNEX-
ION FACILEMENT ACCESSIBLE DOIT ÊTRE INCORPORÉ
DANS LE CÂBLAGE FIXE.
