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.
• If Expansion KSU(s) are installed, turn the power on/off in the following order:
Expansion 3 KSU (V3.5 or higher), 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
demarcation, 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.
