NX100 Pre-installation Manual
Page xvi Issue 3.2 2017-03-31
Use a proper lockout procedure to ensure that another worker cannot accidentally reapply power
while you are performing maintenance on any part of the transmitter or site.
Lightning Hazards
Before opening the transmitter and touching internal parts, remove and solidly ground the antenna
connection.
RF Hazards
A serious RF hazard and very high voltages exist in the vicinity of the antenna and its networks
during normal operations.
Toxic Hazards
There may be devices used in this equipment that contain beryllium oxide ceramic, which is non-
hazardous during normal device operation and under normal device failure conditions. These devices
are specifically identified with “(BeO)” in the Description column of the Troubleshooting Manual’s
parts list(s).
Do not cut, crush or grind devices because the resulting dust may be hazardous if inhaled.
Unserviceable devices should be disposed of as harmful waste.
Other Hazards
Ensure that appropriate fire alarms and fire extinguishers are available. Extinguishers must be suitable
for use on electrical fires.
Many other site safety risks exist. It is beyond the scope of this manual to identify all the risks and
procedures.
WARNING: It is not enough to ground the antenna terminal with
the antenna still connected. Even a small impedance in the ground
strap will result in lethal voltages during a lightning strike.
