The following safety hazards must be observed when performing site prep installation procedures.
DANGER
Electric-shock hazard
Working in severe weather can result in personal injury or death and damage to the equipment.
Never install or perform maintenance during severe weather (high winds, lightning, blizzards, hurricane, etc.).
WARNING
Electric-shock hazard
Some parts of all electrical installations are energized. Failure to observe this fact and the safety warnings may lead to bodily injury and property damage.
For this reason, only trained and qualified personnel (electrical workers as defined in IEC 60215 or EN 60215 + A1 or in the National Electrical Code or ANSI/NFPA No. 70) may install or service the installation.
WARNING
Electric-shock hazard
The power supply lines to the network element are energized. Contact with parts carrying voltage can cause health problems, possibly including death, even hours after the event.
Open and lockout the load disconnect switch in the distribution box to completely de-energize the network element.
WARNING
Inhalation hazard
Inhalation of Beryllium Oxide (BeO) can result in serious illness. The RF transmitter units include components which contain Beryllium Oxide (BeO). In this form, BeO ceramics do not constitute a hazardous material as long as components remain intact.
Do not physically damage or pulverize components which contain Beryllium Oxide.
CAUTION
Service-disruption hazard
Sudden changes in the weather may lead to the formation of condensation on components. Operating the unit when condensation moisture is present can destroy the unit.
Units which show signs of condensation must be dried before being installed and energized.
CAUTION
Electrostatically Sensitive Components
Semiconductor elements can be damaged by static discharges.
The following rules must be complied with when handling any module containing semiconductor components:
Wear conductive or antistatic work clothes (for example., coat made of 100% cotton).
Wear grounded ESD wrist strap.
Wear shoes with conductive soles on a conductive floor surface or conductive work mat.
Leave the modules in their original packaging until ready for use.
Make sure there is no difference in potential between yourself, the workplace, and the package before removing, unpacking, or packing a module.
Hold the module only by the grip without touching the connection pins, tracks, or components.
Place modules removed from the equipment on a conductive surface.
Test or handle the module only with grounded tools on grounded equipment.
Handle defective modules exactly like new ones to avoid causing further damage.
