SYSTEM WIRING
System cabling may be routed concealed or visible as the installation
location requires.
all applicable building codes must be adhered to.
2-5 and Figures 2-2 through 2-5 illustrate the system wiring and
connection points.
AC Power Connection

Connect the power interconnection cable between the power supply and
the KSU.
Do not connect or disconnect the power interconnection cable
while the AC power cord is connected to the AC outlet.
To apply AC power to the power supply,

Do not connect the AC power cord until the installation has
been checked per the SYSTEM CHECKOUT instructions given
later in this chapter.
Line
Connections
The KSU interface connection for the TELCO or PBX lines is a 50-pin,
male connector.
connected from the KSU connector to the demarcation point connector
(typically a 66M-xx connector).
To help insure that foreign voltages, which could appear on
the TELCO lines, do not damage the system, verify that gas
discharge tubes or similar protection devices are installed,
and properly grounded, in all connected TELCO lines.
