2.1 General Precautions
Ensure you take the following precautions when installing the SL2100 system.
• 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 chassis.
• 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 chassis should not be placed on unstable surfaces.
• To avoid damage the plastic parts, never use an electric screw driver to tighten the screws.
• To prevent overheating, do not bundle AC power cords together.
• Make sure the chassis has proper earth ground.
• If Expansion Chassis are installed, turn the power on/off in the following order:
Expansion 2 Chassis, Expansion 1 Chassis and then Main Chassis
2.2 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.
2.3 Site Requirements
･The system should be wall-mounted only. Ensure enough space exists to allow the installation
of additional Chassis and/or a battery box.
･A dedicated 100V-120V/220V/230V/240VAC circuit located within two meters of the Chassis is
required. A separate dedicated AC outlet is necessary for each Chassis.
