E.0 CBR Installaton 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. Page 1 of 3
