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.
