AC Power Supply Requirements
ECI offers the AC_PS-B1U AC/DC converter module for customers who require to power the NPT-1020 from
an AC power source. The AC_PS-B1U plugs directly into the NPT-1020 in the PSA and PSB slots (that is
regularly used to install two INFs when the platform is powered by DC) and provides up to 180 W.
When an extension platform, EXT-2U is also required to be fed from AC, the AC_PS-E2U module can be
used. The module plugs into the EXT-2U and provides up to 180 W.
The following table lists the recommended AC source circuit breakers for feeding the AC/DC convert units.

Laser Safety Requirements
This section describes the laser safety requirements.
3.6.4.1
Laser Classification
The equipment and components with laser devices described in this manual comply with the International
Electrotechnical Commission (IEC) safety standards, including IEC-60825-1 - Safety of Laser Products
(AS/NZS 2211.2) and IEC-825 – Safety of Optical Fiber Communication Systems.
With specific regard to the laser, NPT-1020 equipment complies with laser product performance standards
set by government agencies for Class 1 laser products. The product and its accessories do not emit
hazardous light, and the beam is totally enclosed during all operating modes and maintenance.
