from the assembly.
Install the panel mount equipment in the following arrangement
4.
from top to bottom: 1U blank panel, EAS/EAS2, 1U blank panel,
Controller A, Controller B. Secure the equipment to the main
brackets with black M6 screws (20 places).
Cable the units as shown in sections 3 (Pre-Installation), 4
5.
(Installation), and Appendix C (Cabling Diagrams) of this manual.
Note the following exceptions to ground and power connections.
Cable ties are provided to appropriately dress cables.

Motorola offers a standard EBTS cabinet circuit breaker panel that
8.
receives an external —48V DC power source and provides DC
distribution/overload protection and signal interconnection for the
Site Controllers and EAS/EAS2, however, customers may prefer to
design their own DC power system. In this instance, the customer is
responsible for ensuring that their power source is capable of
sourcing the total power needed for the units. Table 3-3 shows the
power system requirements for the Site Controllers and EAS/EAS2.
Two cables are provided to connect the site controllers and the EAS/
EAS2 to the standard Motorola EBTS circuit breaker panel. The
3083609X01 cable supplies power to both Controller A and the
EAS/EAS2 while cable 3082082X02 supplies power to Controller B.
Both cables employ keyed 3 position female receptacles that
properly plug into the "RTN —48V" input power connectors at the
rear of the Site Controllers and EAS/EAS2. The opposite ends of
these cables employ male connectors that are compatible with the
output of the standard Motorola EBTS circuit breaker panel. For this
installation, the male connectors should be removed. Cut off the
connectors at an appropriate cable length and attach the wire ends to
the power source for the Site Controllers and EAS/EAS2. Table 3-2
shows the proper color coding for these wires.
