PRELIMINARY Safety Precautions
6.2 Safety Precautions
6.2.1 Installation Guidelines
Use the following guidelines when installing LGC Wireless equipment:
1. Provide sufficient airflow and cooling to the equipment to prevent heat build-up
from exceeding the maximum ambient air temperature specification. Do not com-
promise the amount of airflow required for safe operation of the equipment.
2. Be careful when servicing these products. If you are removing the system, turn it
off and remove the power cord first. There are no user-serviceable parts inside the
components.
3. The internal power supply has internal fuses that are not user replaceable. Con-
sider the worst-case power consumption shown on the product labels when provi-
sioning the equipment’s AC power source and distribution.
6.2.2 General Safety Precautions
The following precautions apply to LGC Wireless products:
• The units have no user-serviceable parts. Faulty or failed units are fully replaceable
through LGC Wireless. Please contact us at:
1-800-530-9960 (U.S. only)

• Although modeled after an Ethernet/LAN architecture and connectivity, the units
are not intended to connect to Ethernet data hubs, routers, cards, or other similar
data equipment.
• When you connect the fiber optic cable, take the same precaution as if installing
Ethernet network equipment. All optical fiber SC/APC connectors should be
cleaned according to the cable manufacturer’s instructions.
• When you connect a radiating antenna to an RAU, DO NOT over-tighten the SMA
connector. Firmly hand-tightening the connector is adequate.
WARNING: To reduce the risk of fire or electric shock, do not
expose this equipment to rain or moisture. The components are
intended for indoor use only. Do not install the RAU outdoors. Do not
connect an RAU to an antenna that is located outside where it could
be subject to lightning strikes, power crosses, or wind.
