Mounting in a Rack
Multiple repeaters can be mounted in an open rack without degradation of specification.
12.1.4
AC and DC Input Power Requirements
This section describes the power requirements for the AC and DC inputs, as well as ground, battery,
RF antenna, and system cable connections.
12.1.4.1
AC Input Power Requirements
The SLR 5000 Series Repeater is equipped with a switching power supply, and this assembly operates
from 100–240 VAC at 47–63 Hz AC input power. A standard 3-prong line cord is supplied to connect
the power supply to the AC source.
Use a standard 3-wire grounded electrical outlet as the AC source.
CAUTION: The AC socket outlet must be installed near the equipment and must be easily
accessible.
The outlet must be connected to an AC source capable of supplying a maximum of 500 VA. For a
nominal 110/120 VAC input, the AC source must supply 5 A (minimum). Per R56, the minimum
ampacity of the circuit (and protective breaker) feeding the repeater should be no less than 15 A. For a
nominal 220/240 VAC input, the ampacity requirements can be halved.
12.1.4.2
DC Input Power Requirements
The DC source operates from 11 VDC to 14.4 VDC (17 A max). This DC source must be located in the
same building as the repeater, and it must meet the requirements of a SELV circuit. The appropriate
DC disconnects and current limiting devices must be chosen and implemented per R56.
12.1.4.3
Ground Connection
The repeater is equipped with a ground screw on the back panel of the repeater. Figure 81: Back
Panel Connector Names and Locations on page 129 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:
See the Motorola Solutions 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.
12.1.4.4
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 129 for the location of the DC inlet connector.
