KSU Grounding
To ensure proper system operation and for safety purposes, a good earth ground is required.
A metallic cold water pipe usually provides a reliable ground. Carefully check that the pipe
does not contain insulated joints that could isolate the ground path. If insulated joints exist,
another earth ground source must be used or, if allowed, the joints may be bridged.
A #14 insulated AWG or larger copper wire should be used between the ground source and
the KSU. The wire should be kept as short as possible. It is recommended that the wire be no
longer than 25 feet.
Figure 3-5: Earth Cable between KSU and External RGU
Grounding Instructions
1. Remove about 1½inches of insulation from both ends.
2. Attach one end of the wire to the Ground Lug on the lower left side of the Cabinet 0 by
inserting the wire under the lug screw and tightening the screw securely.
3. Attach the other end of the wire as appropriate to the ground source.
4. Take a DC resistance reading and an AC Volt reading between the chassis ground point
(cold water pipe) and AC ground (third wire AC ground).
The limit is 1V AC and 5 Ohms DC resistance. If a higher reading is obtained, choose a
differentchassisgroundpointandrepeatthisstepuntilasuitablegroundpointisfound.
Grounding to an electrical conduit is NOT considered a good ground!

Power Line Surge Protection
The AC outlet should be equipped with an additional power line transient surge protection
device. Systems using such devices are more resistant to damage from power line surges
than unprotected systems. Power line surges often occur during switching operations and
especially during violent thunderstorm activity.
Protector Specifications-- Installation of a surge protector meeting these specifications
prevents or minimizes the damage resulting from power line surges.
†The Isolation Transformer/Surge Protector shall be a 15 amp self-contained unit that
plugsintoastandardgrounded117VACwalloutlet.
†The wall outlet must be designed to accept a 3-prong plug (2 parallel blades and ground
pin).
†The protector should be fast operating and capable of protecting transients greater than
200 volts.
Lightning Protection
The system provides secondary protection per UL 1459 Specifications. Primary protection
circuitry is the installers responsibility and should be installed per the National Electric Code
(NEC).
KSU AC Power Plug
1. Before plugging the KSU power cord into the AC source, verify that the Power switch on
the AC/DC front panel is in the OFF position.
2. Plug the KSU power cord into the AC outlet and turn the AC/DC Power switch to ON. The
red/green LED on the PSUs should illuminate.
It is recommended that the AC outlet be equipped with an isolation transformer/
surge protection device that utilized MOV protection.

Optional Mounting Racks
Mounting Rack (Floor Model)
1. To install on the floor, use the optional foot.
2. To install the second or third Cabinets, use the screws provided to connect them as in
Figure 3-6.
3. The installation position of the optional foot can be adjusted according to the
environment.

Optional Rack (Cabinet Model)
1. To mount rack, use the optional BRK (Bracket for installation on the rack). Usable rack is
the standard 19”rack. Any 19”open rack can be used.
2. After placing the rack on a flat floor, attach the Cabinet to the rack using provided BRK
with bolts and nuts on both sides as shown inFigure 3-7.

							Ring Generator Unit Installation 3-13
Chapter 3 - System Installation
Ring Generator Unit Installation
The Ring Generator Unit (RGU3) is needed if a SLIB is to be installed in a Cabinet. The RGU3
provides ring voltage and a Message Wait Source. A cable for connecting the RGU3 and KSU
is provided.
1. Mount the unit inside the Cabinet to the bottom side panel on the right with the two
screws provided.
2. Connect the unit to the backplane via CN14 connector (marked on PCB).
PowerSupplyUnitInstallation
The Power Supply Unit (PSU) provides power for the system boards and telephones,
converting AC voltage input to appropriate DC voltages.
Voltage Selector Switch
The PSU can operate from either 110/115 or 220/230 Volts AC based on the setting of the AC
SELECT switch on the lower front of the PSU.
†If local AC is 115 volts, move the switch to the left position to display“115”.
†If local AC is 230 volts, move the switch to the right position to display“230”.Defaultsetup
of the product is 115VAC.
The range of input voltage and the fuse rating of the PSU are as follows:
Power Capacity
The power capacity of the PSU is as follows:
Although, the PSU is equipped with power-line transient protection, an external
Power Line Surge Protector should be installed at the AC outlet to give additional
protection, especially during violent thunderstorm activity. Refer to
“Lightning
Protection”.

Before Installation-- Ensure that the AC plug connected to Cabinet 0 is NOT plugged into
the AC outlet.
1. Place the PSU in the left-most slot in Cabinet 0, aligning the card guides with the PSU PCB
and PSU frame flanges.
2. Slide the PSU into place using the injectors to seat the PSU fully in the Cabinet.
3. Then affix the PSU to the Cabinet with the two screws provided.

PCB Handling and General Installation
Inserting a PCB
1. Hold the PCB by the injector tabs and, with the components facing right, align the top
and bottom edge of the PCB in the card guides.
2. Slide the card into the system and use the injectors to seat the PCB firmly into the
backplane connector.
While it is possible to install and remove system cards with power on, it is not
recommended and could void your warranty.
The system PCBs contain digital circuitry which, while extremely reliable, can be
damaged by exposure to excessive static electricity. When handling PCBs, a grounded
wrist strap should be used to protect the boards from static discharges.

sure when the PCBs are inserted into the card guide and secured in their respective card slots,
that the ground tab on each card mates with the ground tab on each card guide. This ensures
a good ground potential to reduce RFI and EMI interference possibilities.

DIP Switch Positions (SW3)
The MPB also has an eight-position DIP switch, SW3. The default setting is: All ON position.
The function of each switch position is as follows:
Before programmingthe system, dip switch 8 (database default switch) should be placed in
the on position and power cycled off and on to initialize the system database to default. Once
the database has been initialized, switch 8 should be placed in the off position to protect the
database.

Use extra care when removing RS-232 cables from the MPB or SIU boards. Hold the
MPB/MISB card in the card slot before removing the RS-232 cable. Failure to perform
this action may result in the MPB/MISB card being pulled from its slot.
