SECTION 1 INSTALLING THE MAIN & EXPANSION KSUS
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
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 Figure 2-4 Horizontal Arrangement of KSUs on page 2-6 and
INSTALLING THE EXTERNAL BACKUP BATTERY on page 2-20.
• 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.
