ACC CONNECTOR (pgs. 3, 4) Used for external equipment control. 7 INSTALLATION AND CONNECTIONS 2 Power Make sure the [POWER] switch is turned OFF when connecting an AC power cable and a backup battery (emergency power supply). The IC-FR3100/FR4100 series can operate with an AC or DC power supply. If AC power is interrupted when operating the repeater with an AC power supply, power is automatically provided to the [BATTERY] terminals. NOTE: When repeatedly to turning the repeater ON and OFF quickly, the repeater may not turn ON. In this case turn OFF the power switch and wait for a while, then turning power ON again. Mounting the repeater D Using the optional MB-78 An optional MB-78 19 INCH RACK MOUNT BRACKET is available for mounting the repeater into a 19 inch rack. The MB-78 can install the repeater's bottom side and top side. · Bottom side installation q Remove the 2 screws (M4 × 8) from both sides of the side panel (front-end). D In AC operation · The [DC] indicator turns OFF. · Use the supplied AC power cable for connection to a domestic AC outlet. · Extension cords should not be used unless absolutely necessary. Using improper extension cords could result in fire risk. · Usually the battery is continuously charged with a small amount of current from an AC power supply through the regulator circuit in the repeater. Discharging is therefore prevented even if the battery is not used for a long time. w Attach the MB-78 to the bottom side of the repeater. D In DC operation CAUTION: Voltages greater than 16 V DC will damage the repeater. Check the source voltage before connecting the power cable. · The [DC] indicator lights up green. · DO NOT place the backup battery on or near the repeater. Lead-acid batteries should be placed at least 5 m away from the repeater. Use a heavy duty cable to make the connection and be sure both the positive (red) and negative (black) terminals are correctly connected. · Connect cables to the battery in the following order. Connect the DC power cable to the repeater first, then the positive (red) terminal and negative (black) terminal to the battery to prevent an electric shock. · After the battery is connected and the [POWER] switch is ON, the repeater continuously supplies approx. [. . . ] no other object or structure is within 1. 5 m (preferably more). It should be relatively easy to fulfil all these recommendations. If for any reason such minimum distances are impossible to guarantee then some type of access control fence or barrier around the antenna installation should be provided. Should a Yagi type antenna be used then you will have to obtain a 3 dimensional polar plot of the radiation characteristic from the manufacturer and evaluate the clearance distances in both vertical and horizontal planes. · Operating Notes All of the above comments on RF safety assume that the radio is transmitting continuously in a constant carrier mode such as FM or RTTY etc. [. . . ]
