SECTION 1 INSTALLING THE MAIN KSU

1.1

Before Installing the KSU

1.1.1

General Precautions

To avoid shock or equipment damage, do not plug in or turn the system power on before

completing the installation process.
Avoid working with the Equipment during electrical storms.

Use only commercial AC power to prevent shock or fire.

Use the power cord supplied with the KSU.

Install batteries with the correct polarity to prevent damaging equipment.

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected

at the network interface.
To avoid damage, the KSU should not be placed on unstable surfaces.

To prevent overheating, do not bundle AC power cords together.

Make sure the KSU has proper Earth ground.

1.1.2

Preparations

Make sure the necessary tools (screw driver set, pliers set, etc) are available.

Make sure you have a building plan showing common equipment, extensions, the telecom

demarcation, and earth ground location. The installation site must meet the following site /

environmental requirements.

1.1.3

Site Requirements

Main KSU can have the optional Battery Box connected, before deciding on the mounting location refer
to 1.3 Wall-Mounting the KSU and Section 2 INSTALLING THE EXTERNAL BACKUP BATTERY.
The system without the IP4WW-Battery Box should be wall-mounted only. The system with the

IP4WW-Battery Box can be installed on either the floor or wall (horizontally). Ensure enough
space exists to allow the installation of KSU and/or battery box.
A dedicated 100V-120V/220V/230V/240VAC circuit located within two meters of the KSU is

required. A separate dedicated AC outlet is necessary for the KSU.
1.1.4 Environmental Requirements
Meeting established environmental standards maximizes the life of the system. Make sure that the site
is not:
In direct sunlight or in hot, cold or humid places.

In dusty areas or in areas where sulfuric gases are produced.

In places where shocks or vibrations are frequent or strong.

In places where water or other fluids comes in contact with the equipment.

In areas near high-frequency machines or electric welders.

Near computers, telexes, microwaves, air conditioners, etc.

Near radio antennas (including shortwave).
