1.1 Before Installing the KSU(s)

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 loca-
tions.
• 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.
• If Expansion KSU(s) are installed, turn the power on/off in the following order:
Expansion 2 KSU, Expansion 1 KSU and then Main KSU

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 demarca-
tion, and earth ground location. The installation site must meet the following site / environmental
requirements.

1.1.3 Site Requirements

Each Main or Expansion KSU(s) can have the optional Battery Box connected, before deciding on the
mounting location refer to
INSTALLING THE EXTERNAL BACKUP BATTERY on page
• 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 additional KSU(s) 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 each 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.
