12.3.1.2
DC Input Power Connection/ DC Charger Connection
For DC operation, the DC source power is connected to the repeater through the DC power inlet
connector shown in Figure 81: Back Panel Connector Names and Locations on page 124. The
operation is also described in the “Battery Connection” section of this chapter. The DC source must be
located in the same building as the repeater, and it must meet the requirements of an SELV circuit.
CAUTION: Ensure that the appropriate voltage is connected with a nominal 13.6 VDC (11 –
14.4 VDC).
12.3.1.3
Ground Connection
The repeater is equipped with a ground screw located on the back panel. Figure 81: Back Panel
Connector Names and Locations on page 124 shows the location of the grounding screw. Connect the
ground screw to the site ground point. The size of the wire used for this connection must be 8 AWG
minimum.
CAUTION:
Refer to Motorola Quality Standards Fixed Network Equipment Installation Manual R56 (which
can be obtained by ordering CDROM 9880384V83), for complete information regarding
lightning protection.
The repeater should only be connected to a battery supply that is in accordance with the
applicable electrical codes for the end use country; for example, the National Electrical Code
ANSI/NFPA No. 70 in the U.S.
12.3.1.4
Battery Connection
Battery backup interface offers the capability of connecting to battery backup power in the event of an
AC power line failure. The battery backup system is connected to the repeater through the DC inlet
connector on the rear panel of the repeater. See Figure 81: Back Panel Connector Names and
Locations on page 124 for the location of the DC inlet connector.
CAUTION: The repeater should only be connected to a battery supply that is in accordance
with the applicable electrical codes for the end use country; for example, the National Electrical
Code ANSI/ NFPA No. 70 in the U.S.
12.3.1.5
RF Antenna Connections
The transmit and receive antenna RF connections are made using two separate connectors. Coax
cables from the receive and transmit antennas must be connected to their respective connectors. The
position of these connectors is shown in Figure 81: Back Panel Connector Names and Locations
on
page 124, and their respective connector types are noted in Table 42: Connector Type and Primary
Function on page 124.
12.3.1.6
System Cable Connections
System connections are made through the Aux and/or Ethernet connectors located on the back panel
of the repeater. The positions of the Aux and Ethernet connectors are shown in Figure 81: Back Panel
Connector Names and Locations on page 124.
See Auxiliary (Aux) on page 71 for a description of the signaling that is supported by the Aux
connector.
