About Safety
All Nautel transmitters are designed to meet the requirements of EN60215, Safety Requirements for
Radio Transmitters. The philosophy of EN60215 is that the removal of any cover or panel that can only
be opened using a tool is a maintenance activity, and that any person performing a maintenance
activity is expected to be trained for that activity. Under EN60215, it is assumed that trained personnel
will be knowledgeable and will take precautions such as removing all power to the transmitter before
accessing its components.
Electrical Hazards
To remove power from the transmitter, switch off and lock out the ac power. Some transmitter models
will have amber LEDs at the bottom rear of the cabinet that glow to remind anyone who has not turned
off the power that the system is live and serious danger is present.
DANGER - HIGH VOLTAGE
Indicates dangerous voltage (in excess of 72 volts), capable of causing a fatal
electrical shock, are present on or near parts bearing this label.
Mount the transmitter ac power disconnect switch/breaker close to the transmitter so that it can be
reached quickly in an emergency. Clearly label the switch/breaker (e.g., EMERGENCY SWITCH ).
After turning off the power, always perform a measurement to confirm that the power is off before
touching anything within the transmitter. If the wrong breaker was opened, the equipment will be live.
Use only a non-contact voltage probe or a safety voltmeter (available from vendors such as Fluke, Ideal,
and Teagam).
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.
WARNING: It is not enough to switch off RF power. The power line is still
connected. Disconnect and lock out the upstream supply before servicing.
WARNING: Do not use an ordinary multimeter to check for voltage, since it may
have been left inadvertently on the AMP (A) range, triggering a short and an arc
blast that could result in severe burns and even death.

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 containing 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.
