 the BUSINESSCOM PLUS 36 KSU-B (P/N 15201)
according to the preceding paragraph.
2 .   Remove the top of the KSU.
3. Position the Expansion Cabinet on top of the KSU.
4. Drill pilot holes at these points, and insert
fasteners having a 
 shank diameter. Screw
in fasteners until the clearance between the
fastener head and the mounting surface is 
 inch.
5. Refer to Figure 2-4 BUSINESSCOM 64 KSU-B

Connect the gray ribbon cables  and  in
the Expansion Cabinet to the connectors in the
KSU, and make sure that the connections are
secure.
Connect the two power cables on the KSU to the
connector in the Expansion Cabinet. Make sure that
the connections are secure.
Install the two metal plates on the sides of the
two cabinets (where the cabinets meet).
Tighten each fastener until the Expansion Cabinet
is securely attached to the plywood backboard.
Place the top of the KSU on top of the Expansion
Cabinet.
Expansion
Install an additional small piece of 14 AWG wire
to the ground lug on the side of the KSU.
Connect the other end of the wire to the ground
lug on the expansion cabinet.
Mounting the
Power SupplyMount the power supply for a BUSINESSCOM PLUS system
(with/without a Battery Backup Box 
 at least six
inches above the KSU or to one side of it, and mount
it within six feet of the dedicated AC outlet as
follows:
1. Mark four points on the plywood backboard. These
points correspond to the centers of the mounting
holes.
2. Drill pilot holes at these points, and insert
fasteners having a #10 shank diameter. Screw in
fasteners until the clearance between the fastener
head and the mounting surface is 
 inch.
3. Hang the power supply on the four fasteners.
4. Tighten each fastener until the power supply is
securely attached to the backboard.
  
* For installation of the Battery Backup Box, see
Battery Backup Box in INSTALLING OPTIONAL EQUIPMENT.

							II-2INSTALLING THE KSU AND POWER SUPPLY
Grounding the
Power Supply ,The power supply is grounded through the third-wire
ground lead in the AC power cord.
For BUSINESSCOM PLUS 
 systems, connect a
grounding wire 
 AWG or heavier) between the KSU
grounding lug and the power supply ground lug to
prevent electromagnetic interference.
Connecting the
Power Supply to the KSU
WARNING: BEFORE CONNECTING OR DISCONNECTING THE POWER
SUPPLY, THE POWER SUPPLY MUST BE OFF.
---
Turn off the power,and connect the power supply to
the KSU with the supplied cable. On a BUSINESSCOM PLUS
the connection for the power supply is on the
bottom of the KSU. On a BUSINESSCOM PLUS 
this connection is on the right-hand side and the
connection for the KSU is on the lower left-hand
corner (cover removed).The ground lugs of KSU-Bs are
on the left side of the 
Installing the
Surge Protector 1.Install the power line surge protector at the
dedicated AC receptacle to minimize the effects
from high static voltage, low level transients,
and ripple effects.
2. Connect this unit according to the manufacturers
instructions.
For information on fuses,see POWER SUPPLY FUSES in
Part 3 MAINTENANCE AND TROUBLESHOOTING.
Powering up
the System 1. Plug the AC power cord into the power line surge
protector.
2. Turn on the power supply.
o On the BUSINESSCOM PLUS 
 the three power,
 on the right side of the power supply should
light.
o On the BUSINESSCOM PLUS  all the power supply  (green and red) should light. If they 
do not,see TELEPHONE TROUBLESHOOTING in Part 3). . 
Powering down
the System1. Turn off the power supply.
2. Unplug the AC power cord.

							II-2 INSTALLING THE KSU AND POWER SUPPLY
Initializing
the SystemFor a complete system initialization:
 Disconnect lithium battery on B-MPU- or 
PCB.
2. Place the WR switch in the up position (initial)
position (see Figure 2-5
Programming Switch WR,
B-MPU-PCB).
3. Plug in the power supply, and turn it on.
After approximately 10 seconds:
1. Move the WR switch to the down position
(i.e.,
normal).
2. Plug in the lithium battery.
Data in memory is now
protected against power failure.
3. Remove Programming Button Access Door. Use a 
edged,non-conductive item to press programming
button (see Figure 2-6
Entering the Programming
Mode).
Program 91 initializes the Speed Dial Number bins,
resets the Alarm settings,
and loads default values
under the telephone DSS keys.
1. Enter Program Access Code 91.
2 .  Press 
Display reads: 91 A
3 .  Press 
and press # to exit program.
To exit programming mode,
Reinitializingpress programming button.
the System
If it is necessary to reinitialize the system but
retain the contents of Speed Dial Number bins and
DSS key assignments, proceed as follows:
1. Without disconnecting the lithium battery, move
WR switch to up (initial) position.
2. After the power supply has been off for at least
10 seconds,
move WR switch to down (normal)
position.
3. Reprogram the system.

programmable and may differ from the above. The 600
ohm resistor must be installed across the AT/AR leads
for the programmed extensions.
Mount a modular jack assembly, 
 or  at
each station location.
Use two-pair twisted station cable from the KSU and
station blocks to the modular jacks at the telephones.
Home run station cabling to the connecting block. The
cabling should not exceed 1,000 feet for 24 AWG wire
or 1,500 feet for 22 AWG wire.

An Off-Premises Extension  on a BUSINESSCOM PLUS
system requires 
 OPX lines.
Do not run cable from
the KSU to extensions or stations in other buildings.
For an OPX,the BUSINESSCOM PLUS
