Important safety instructions

The following options for the ANT-20SE are fitted with laser output devices:
• BN 3035/90.40 through BN 3035/90.59
• BN 3035/91.40
• BN 3035/91.41
• BN 3035/91.53 through BN 3035/91.59
Optical radiation with wavelengths in the range 1300 to 1600 nm is present at sockets [18], [47]
and [103].
Maintenance and repair work on the laser sources should only be carried out by qualified
service operatives familiar with the risks involved.
The laser source is active if the yellow LED next to the connector is on.
Invisible laser radiation
Laser light can cause irreparable damage to the eyes, particularly to the retina.
⇒ Never look directly into the generator outputs [18], [47] and [103] or the connector end
surfaces of the connected cables (free ends) if the laser sources are activated.
⇒ Never use a microscope to check the generator outputs if the laser sources are activated.
Caution
⇒ Do not activate the laser sources until all measurement connections have been made.
The output power at socket [18] of the STM-4/OC-12 module is within the limits for a
CLASS 1 LASER PRODUCT.
The output power at socket [47] or [103] of the STM-16/OC-48 module or STM-64/OC-192 is
also within the limits for a CLASS 1 LASER PRODUCT (IEC 825-1: 1993) during normal
operation. Under fault conditions, the output power level may exceed these limits and the output
is then a CLASS 3A LASER PRODUCT (IEC 825-1: 1993).
