not be used in hazardous situations such as lightning storms. It is intended to be used
for temporary connections only.
The BNC, bantam and RJ connectors must be connected to Safe Extra Low Voltage
(SELV) circuits only and must not be connected to any circuit carrying dangerous
voltages.
1.8.3 Laser safety
The following only applies if optical interfaces are fitted:
WARNING: Class 1 Laser Product.
Optical radiation with wavelengths of 1310nm and/or 1550nm is present at the optical
connectors. Each interface is active if the yellow LED next to the connector is on. The
laser warning icon, , is also displayed with a yellow background when the ANT-5
laser source is active. Maintenance and repair work on the laser sources should only
be carried out by qualified service operatives familiar with the risks involved.
WARNING: Invisible laser radiation.
Laser light can cause irreparable damage to the eyes, particularly to the retina.
• To deactivate the ANT-5 laser source (Tx), clear the Laser On checkbox in the
Interface Setup Tx panel. See Section 4.4.2 for further details.
• Never look directly into the generator outputs or the connector end surfaces of the
connected cables (free ends) if the laser sources are activated.
• Never use a microscope to check generator outputs if laser sources are activated.
• Do not activate laser sources until all measurement connections have been made.
1.8.4 Cleaning optical connectors
To maintain error-free operation, the ANT-5 optical connectors should be regularly
cleaned using a pressurised optical duster which is intended for the purpose. The
optical connectors are provided with dust caps which should always be used when an
optical patch lead is not connected.
Patch lead connectors should also be cleaned by an approved method, such as a
pressurised optical duster or a cassette-type cleaner, according to the manufacturer’s
instructions. Dust caps should be fitted to the patch leads when they are not in use.
1.8.5 Optical attenuators
WARNING: Equipment Damage
Care must be taken not to connect a long-haul (high power) transmitter directly to the
receiver, since this can overload or even damage some receiver modules. By
connecting an external optical attenuator this restriction can be overcome.
