INSTALLATION
MOUN’I’ING CONSIDERATIONS
@The KSU and power supply cabinets should be attached vertically to
any sturdy, flat, surface.They may be vertically rack mounted if
desired.The power supply cabinetcan be mounted so that the power
connector and fuses are facing either toward the right side or
toward the left side of the mounting location.
*The power interconnection cableis four feet in length.Locate the
cabinets with respect to each other so that this cable will...

3.Full scale mounting templates are supplied in the packing boxes.Hold or tape them to the mounting surface, and mark the location
of the mounting holes on the mounting surface as they are located
on the templates.The mounting dimensions and general equipment
locations are shown on Figure 2-l.
4.Drill holes in the mounting surface of a proper size to
accommodate the hardware being used.If necessary,prepare these
holes with inserts,anchors or other attachment devices as
dictated by...

SYSTEM WIRING
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-l through
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...

IMI 66-047Installation
The polarity between the individual wires in a particular
voice or data pair is not critical; however, do not connect
the voice circuits to the data circuits.
IMPORTANT NOTE
Station ports are programmed for the type of equipment that
is to be connected to them.A 22 Line/Feature 
Keyset must
be installed at station port 
10 and/or station port 11 as
Class Of Service programming is performed from those ports.
DSS/BLF Console Connections--
The system provides two console ports.The...

Installation
*Connect the auxiliary-pair from the auxiliary connector block to
the desired termination.
@Connect an appropriate line cord between the auxiliary jack and
the auxiliary source equipment.
A-Lead Control Device Connections
__-- ---- --.--------
The KSU can detect an A-lead (A and Al) control signal when it is
applied to lines 13 
- 16.An A-lead control device can be
bridge-connected to these lines via terminal clips on the J-4 station
connector block.Refer to Table 2-4 and Figure...

IMI 66-047Installation
The system defaults to 7-bit data with no parity at a baud rate of
1200.Configure the device,
per the manufacturers instructions, to
match the data format and baud rate that is set by 
CQS programming.Grounding
System
It is required that a grounding wire,separate from the three wire AC
line cord, be used.A ground stud is located on the KSU and on the
power supply for this purpose.Wire 
$10 or #12, insulated, solid
copper wires between these ground studs and a reliable earth ground...

Area Paging Interface 
- Station PA Port
--------- - __-_ - -
Any unused station port can be programmed to be a PA port instead Of a
telephone station port (see Chapter 3 for programming details).
~The audio input of an external paging amplifier can be connected to
the audio pair of the station port as illustrated in Figure 2-3.
l The audio input connection must be isolated with a 600 ohm to 600
ohm audio matching transformer.Terminate the audio input of the
PA system with a 620...

Installation
Key System/Multifunction 
jHybrlLd_r c_O_nfigm-__-~-_------
The system can be configured to operate as either a key system or as a
multifunction (hybrid) system.
Configuration is by way of a wire strap placed between clip terminals
27 and 28 of station connector block J-4.
The KSU is shipped from the factory as a key system (KF).
To convert
operation over to the multifunction 
(MF) system, add the strap.
The KF and MF designations are equipment type 
catagories as stipulated
in...
