NPT-1020 Installation and Maintenance Manual
W
ARNING: To reduce the risk of exposure to hazardous radiation, note the following:
When performing maintenance and other activities on equipment using lasers, it is

recommended that you use protection goggles for the wavelength range of 1300 nm to
1600 nm.
Only authorized personnel must carry out hot insertion or swapping of an optical module

or optical interface module.
To prevent irremediable damage to your eyes, avoid looking into the fiber when

hot-removing and/or inserting a fiber termination.
Place plastic covers on module fiber ports and fiber terminations that are not currently in

use.
Do not operate controls, make adjustments, or perform procedures associated with the

laser device other than those specified herein.
It is strictly forbidden to interfere with any protective devices and interlocks that are used to
prevent direct exposure to the laser beam.
