							PART 2INSTALLATION
INSTALLATION
INTRODUCTIONThe INSTALLATION Section provides detailed procedures
for installing BUSINESSCOM PLUS Systems. This section
presents the system installation in five parts:
o PREPARING FOR INSTALLATION
shows how to select an installation site. It also
indicates the tools and test equipment needed to
install the system.
o INSTALLING THE KSU AND POWER SUPPLY
shows how to install, connect, and ground the
systems KSU and power supply. It tells how to
install a surge protector and explains how to
power up and power off the system.
o INSTALLING STATION CABLING AND SYSTEM CONNECTIONS
shows how to mount the connecting blocks, install
the systems station cabling, and connect the CO
lines.
o INSTALLING THE  AND CHECKING WIRING
explains the static precautions to observe when
handling 
and install them in the KSU. Shows
how to verify the DC voltage measurements of the
systems station cabling and wiring from the MDF
 Block.
o INSTALLING OPTIONAL EQUIPMENT
explains how to install the equipment and
accessories required for the optional features.
WARNING: ALTERATIONS OR MODIFICATIONS OF THIS EQUIP-
MENT NOT EXPRESSLY SHOWN IN THIS MANUAL VOIDS APPLI-
CABLE WARRANTIES, FOR PROTECTION AGAINST RISK OF
FIRE, REPLACE FUSES ONLY WITH FUSES OF THE SAME TYPE
AND RATING.
Read this entire section before proceeding with the
actual installation.

							PREPARING FOR INSTALLATION
Site
RequirementsMeeting and maintaining established environmental
standards maximizes the life of your system. Be sure
that the site you select for installing the KSU is:
o a clean, dry,and secure location.
o not accessible to unauthorized personnel
o free from static electricity (e.g., dry copiers)
and excessive vibration (e.g., heavy machinery)
o removed from caustic chemicals
o environment-controlled
This site must also comply with the standards out-
lined in the Bell Functional Product Class Criteria
of September, 1978, in PUB 48002. Paragraph 3.4.3.2
Indoors With Environmental Control:
Equipment intended for use in a controlled environ-
ment is exposed to temperatures between 40 degrees 
 degrees  and 100 degrees  (38 degrees  and
relative humidities between 5 percent and 95 percent.
Mount the KSU on the wall only. Provide  ample  room  at
the installation site for mounting the KSU along with
the necessary connecting blocks and any ancillary
equipment.Maintain at least 3 feet (915 cm) between
the room ceiling and the top of the KSU. Always allow
adequate space for air circulation.
The site must have a dedicated NEMA 
 outlet with
a 117 VAC 
 60 Hz and a  circuit for the power
The AC service outlet must be located within
six feet of the power supply location. The AC service
must provide a third-wire  ground.
In addition to the third-wire ground in the AC circuit,
be sure to provide a separate earth ground for the
KSU.(The third wire of the AC line cord is not an
acceptable earth ground.) The earth ground must be
within 25 feet (7.6 
 of the installation. A cold
water pipe that is metallic throughout (including all
joints and sections) generally provides a good earth
ground.
Site Summary
CheckBefore installing the KSU, check the following
conditions:
o Location acceptable
o AC line installed
o Provisions for ground
o 
 lines available
o Primary protection installed

female type 57 connector on the other) for station
connections
o 25-pair cable terminated with a female connector on
one end,male on the other,
for connection to 
o Modular line cord for each extension (for 
tion to   jacks)
o Two-pair twisted station cable, enough to connect
each modular jack to KSU 
 not use random twisted
I-wire inside [quad] cable or 25-pair cable.)
o 14 AWG (or heavier) grounding wire
o 
 connecting blocks with bridging clips
o 
 or  modular station jacks with 
type terminals
o Power line surge protector (should be a 
contained,
three-prong grounded receptacle with a
 capacity or equivalent, such as EFI Model
DPI 253, TII Model 439)
o Appropriate mounting hardware and fasteners
o Bridging clips for the blocks

							PREPARING FOR INSTALLATION
Before installing the system, be sure to:
o Unpack all the telephone equipment.
o Compare the equipment received with a list of
equipment ordered.
o Check for any physical damage.
o Check that all components are on site.
o Verify that a building plan is complete and on
site.This plan should show the location and type
of telephone instrument, extension numbering, and
any special considerations.
Hanging the
BackboardReview the installation layout drawing (Figures 2-1
through 
and locate the area for the backboard.
Plan the layout of equipment on the backboard. Con-
sider optional equipment and future expansion. The
Main Distribution Frame 
 is mounted on the same
plywood backboard that is used for mounting system
equipment. If located in a damp environment or on
masonry,the plywood should be painted or sealed.
CAUTION: ALLOW ROOM FOR CHANGES AND EXPANSION WITH
YOUR KSU AND CONNECTING BLOCK MOUNTING LOCATIONS.
PLACE EQUIPMENT ON MOUNTING SITE FOR GOOD VENTILATION,
DIRECT LIGHTING, AND EASY SERVICE.
Attach the plywood to the designated location with the
proper  fasteners. Using the installation layout, mark
the equipment layout on the backboard.
Mounting the KSU 
When unpacking the KSU from the shipping carton,
be sure to remove 
 hardware.
2. Remove the mounting bracket screws from the KSU,
and position the brackets.
3. Using the KSU  a s  a  guide,
mark four points on the
plywood backboard.
These points correspond to the
centers of the mounting holes.
4. Drill pilot holes at these points, and insert
suitable fasteners having a #10 shank diameter.
5. Hang the KSU on the four fasteners.
6. Tighten each fastener until the KSU is securely
attached to the backboard.
NOTE: D o  not install 
 at this time. If a modular
connector is used on the BUSINESSCOM PLUS 
 the
KSU mounting brackets must be repositioned. (See
Modular Connector in INSTALLING OPTIONAL EQUIPMENT.)
Grounding
the KSU 1 .  Connect the ground wire from the cold water pipe
ground or ground rod to the side of the KSU. This
wire should be as short as possible and no longer
than 25 feet (7.6
