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.
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.
After turning off the ac 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.
