About safety

All Nautel transmitters are designed to meet the requirements of IEC215, Safety Requirements for Radio

Transmitters. Sequenced key interlocks are offered as an option for those customers that require them.

The philosophy of IEC215 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 IEC215, 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 three-phase power and then wait

10 minutes for the capacitor bank to discharge. There are several ultra-brite LEDs that glow inside

the cabinet to remind anyone who has not turned off the power that the system is live and that there

is serious danger.

Mount the transmitter disconnect close to the transmitter so that it can be reached quickly in an

emergency. Clearly label the disconnect.

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).

WARNING: It is not enough to push the front panel button that

removes RF power. The power line is still connected and the three

phase rectifier and the large capacitor bank is still charged and is

LETHAL. Even when the three phase power is switched off and "locked

out," the capacitor bank is still charged and requires 10 minutes to

completely discharge.

WARNING: Do not use an ordinary DVM to check for voltage, since it

may have been left inadvertently on the AMP range, triggering a short

and an arc blast that could result in severe burns and even death.

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.

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.
