Installation
I
IMI 66-031 ’
To apply AC power to the KSU, connect the AC power
grounded,
three-wire, 117VAC electrical outlet. A
cord to a properly
plug-in, power line
surge protector should be installed between the KSU power cord and the
AC outlet.
Do not connect the AC power cord until the installation has
been checked per the instructions given later .in this
chapter.
It is recommended that a grounding wire,
separate from the three wire
AC line cord, be used.
Some local codes may require this use- A
ground stud is located at the lower right corner of the KSU for this
purpose. Wire a 810 or #12, insulated,
solid copper wire between this
ground stud and a reliable earth ground such as a metal cold water
pipe or a building frame ground.
mo sets of relay closure contact points, are available at the Jl
c
station connector block. One set (clips 45 and 46) provides a relay
contact closure whenever any of the TELCO lines, connected to the KSU,
ring. The other set (clips 47 and 48) provides a relay contact
closure whenever station 17 rings.
These contact closures track the
ringing pattern in both cases. The contacts are closed during the
ring on period and are open during the silent period.
A typical connection to these terminals is illustrated in Figure 2.
Refer to the paragraph headed -3 ~~JJJJJ &.J+Q&~~ for a discussion
for using these terminals in this alternate paging function.
m
Do not exceed a 0.4 amps at 24 volts load on these control
terminals.
If the load requirements exceed this limit,
connect the load through an external relay.
DO NOT CONNECT
THESE CONTROL TERMINALS DIRECTLY TO THE 117VAC LINE.
