Installation 
SYSTEM 
HIRING 
System cabling may be routed concealed or visible as the installation 
location requires. Good engineering practices 
must 
be observed and 
all applicable building codes 
must be adhered to. 
Tables 2-1 through 
2-5 and Figures 2-2 through 2-5 illustrate the system wiring and 
connection points. 
AC Power Connection 
- 
To apply AC power to the KSU, 
connect the AC power cord to the NEMA 
S-1SK outlet which supplies the dedicated 117VAC @ 15 AMP electrical 
power. 
A plug-in, power line surge protector should be installed 
between the KSU power cord and the AC 
outlet. 
00 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 SO-pin, 
male connector. A 25-pair cable, properly terminated, must be 
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 oevices are installed, 
and properly grounded, in 
all connected TELCO lines. 
Station Connections 
_-_--- -_- 
Connections between the 
KSU and the stations are typically via type 
66M-xx connector 
blocks which are cable connected to the KSU SO-pin 
male connector. 
The maximum distance allowed from the KSU to the 
station is 1500 feet using #24 gauge, twisted-pair 
cable. 
If spare conductors exist in the cables that are run between the KSU 
66M-xx connector 
block and the station jacks, it is a good practice to 
connect them to earth ground. Doing this may help prevent them from 
inducing radio frequency and/or AC interference into the system.
