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 Wall-Mounting the KSU on page 2-3
BATTERY on page 2-14.
• 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.
