REQUIREMENTS
High Leakage Current
Connect permanent earthing conductor before connecting telephone lines.

A supplementary equipment earthing conductor is to be installed
between the product or system and earth, that is, in addition to the
equipment earthing conductor in the power supply cord.

The supplementary equipment earthing conductor may not be
smaller in size than the unearthed branch circuit supply
conductors. The supplementary equipment earthing conductor is
to be connected to the product at the terminal provided, and
connected to earth in a manner that will retain the earth connection
when the power supply cord is unplugged. The connection to earth
of the supplementary earthing conductor shall be in compliance

BATTERY BACKUP
The InfoSet 408 system has battery backup functions for system backup and for
memory backup.
10.1
System Backup
During a power failure, the system is backed up using a rechargeable
battery. This battery backup supports all system operations for
approximately 30 minutes.
10.2
Memory Backup
The B408-B10 KSU has a lithium battery installed to provide backup of
system memory. The system memory (programmed data) is retained for a
minimum of two years.
1 - 12
System Overview

Installation

SECTION 1
BASIC INSTALLATION
This section provides instructions for the basic installation of the system. Before
the system is operational the backup battery must be attached, the lithium battery
that retains system memory must be installed, the memory backup switch must be
moved to the "Hold" position, and the system must be wall mounted.
There are two standard configuration which can be expanded to a maximum of
four trunk lines (ports) and eight telephones by purchasing the necessary
expansion boards and installing them. Instructions for installing the expansion
boards are provided in Section 2 Installing Electronic Telephone Units on page
2-10.

Opening the KSU and Attaching the Batteries
The two batteries, located in the lower left corner of the KSU, provide
complete system backup power for approximately 30 minutes during power
outages. This provides backup for the entire system (the key system and
telephones) in case of a power outage. It is important that these be
connected before the system is installed.
1.
Remove the cover by loosening the two bottom screws with a Phillips
head screwdriver (the screws remain in the cover to keep from
misplacing them). Pull the cover away from the KSU and lift upward.

2.
Locate the backup batteries in the lower left side of the KSU. Identify
the battery cables, which are marked with blue and yellow tags.
Attach the blue tagged battery cable connector to the blue battery
terminal labeled CN3 (BATT1) and the yellow tagged battery cable
connector to the yellow battery terminal labeled CN4 (BATT2). The
battery terminals are located on the backplane of the KSU. The
connector tab should be placed over the terminal tab. There is only
one direction the tabs can be placed into the connector terminals,
therefore, you cannot attach them incorrectly.

Wall Mounting the KSU
A wall mounting template is provided with the KSU to help mark the
position of the KSU on the wall.
1.
Use the wall mounting template to mark the position of the KSU on
the wall. Be sure to select a sturdy wall (not metal).
2.
Insert two of the provided Phillips head wood screws into the wall.
Leave about 1/2" of the screw extruding from the wall.
3.
If the cover has been replaced, remove the KSU cover by loosening
the two bottom screws with a Phillips head screwdriver (the screws
remain in the cover to keep from losing them). Pull the cover away
from the KSU and lift upward.
4.
Hang the KSU onto the wall by matching the holes on the back of the
KSU with the screws in the wall. Lift up on the KSU and then lower
the KSU over the screws.
5.
Insert the two remaining Phillips head wood screws into the holes
located at the bottom corners of the KSU and tighten all of the wood
screws.

Overview , Section 3 Power Requirements on page 1-5 for AC input
requirements.) Your system should now be fully operational. You
can use the system with the factory selected defaults or you can use
PC Programming or Telephone Programming to customize your
system. (Refer to Chapter 6 Telephone Programming on page 6-1

function that requires a relay contact. The power ratings are: 24 Vdc. 1A
or 120 Vac, 0.5A.
1.
Be sure the system is turned off during the installation process.

ECTION 2
INSTALLING ELECTRONIC TELEPHONE UNITS
Electronic Telephone Units (ETUs) can be installed at the same time that the KSU
is initially installed or individually as needed. The instructions for each individual
ETU assumes the unit is being installed at a later time, therefore, there are steps
which will not apply (i.e., turning the KSU off/on and removing the cover). If
installing the unit(s) at the same time as the KSU, ignore the steps that are not
applicable.
2.1
Installing the ESI(3)-B10 ETU
This board allows three additional telephones to be connected to the
system. A maximum of eight telephones can be connected to the system
when this board is installed.
1.
Be sure the system is turned off during the installation process.
2.
Remove the cover by loosening the two bottom screws with a Phillips
head screwdriver (the screws remain in the cover to keep from
misplacing them). Pull the cover away from the KSU and lift upward.
(Refer to Figure 2-1 Removing the Front Cover on page 2-2.)
3.
Carefully remove the ESI board from the protective packaging. Use
a wrist strap that is connected to the frame ground on the KSU to
avoid static discharge and possible damage to the KSU.
4.
Locate the area on the KSU backplane marked ESI and slide the ESI
board between the grooved posts. Press firmly down on the board
until the connector on the ESI board (labeled CN1) and the connector
terminal on the KSU backplane (labeled CN7) are securely attached.
