PRECAUTIONS ON INSTALLATION & WIRING
A CAUTION
★ Do not connect AC wires to any terminal on any unit, as fire or unit damage may occur. Connect only the specified
power source on +, - terminals.
★ Do not install more than one power supply (PS-12C or PS-12F or PS-12A) for an entire LEF system.
★ Do not attempt to install or connect wires on LEF equipment while system’s power supply is plugged in.
★ LEF masters and related equipment, except door station, are designed for indoor use only. Do not install outdoors.
IMPORTANT
★ There is no need to disassemble the equipment for installation, other than to open the unit to connect the wires to the
back case. Do not access the PC board or components unless properly qualified.
★ Any other manufacturer’s products installed with this system (power supply, external signalling device, etc.) are not
covered under Aiphone’s warranty.
★ Do not mount LEF equipment in the following places, as it may cause the system to malfunction:
• Fligh or extreme cold temperature areas: under direct sunlight, near equipment that varies in temperature, in front of
air conditioner, inside a refrigerated area, etc.
• Places subject to moisture or humidity extremes.
• Places subject to environmental conditions, such as dust, oil, chemicals, salt, etc.
★ LEF units are electronic devices, which must not be subjected to water or any other liquid.
★ Severe weather conditions, such as lightning storms, may cause damage to LEF equipment.
We recommend that power surge protection be installed as follows: (Flowever, this does not guarantee that no
damage will occur).
• If the power supply has a GROUND terminal, take it to an earth ground. In this case, a separate surge arrester is
not necessary.
• When using a power supply that has no GROUND terminal, install a surge arrester near the output as shown.
• Additional SA-1 surge arresters can be installed to protect communication lines. One SA-1 per 2 wires on master
station.
