I. INTRODUCTION
A. NRG Spidar Vertical Profiler
NRG Spidar is a vertical profiling pulsed direct detect Lidar specifically designed for wind measurement
within the wind energy industry. Spidar remains the only direct detect Lidar in use by wind energy
professionals globally for early stage prospecting, wind shear validation, horizontal uncertainty
reduction, and as a permanent met mast replacement on operating wind farms.
B. Direct Detect Lidar and the Cross Correlation Method
Laser pulses from one Spidar beam sample the atmosphere. The reflected intensity of these pulses are
received, analyzed and sampled in time. The sampled time-series represents the aerosol density in the
line of sight of the transmitted pulse.
Figure 1: Spidar Pulsed Sampling
Aerosol density structures persist over time and travel with the wind.

Laser pulses from the downwind Spidar beam sample the atmosphere. The same aerosol density
signature is identified. This establishes the time of flight between the two beam locations. Combined
with the known distance between the two locations, Spidar is able to determine both wind speed and
direction.

II. SAFETY AND WARNINGS
This section details the standards and classifications to which the Spidar system is manufactured and
also highlights potential hazards and handling requirements. These are for guidance purposes only. The
customer should take all necessary care to ensure safe use of the equipment.
A. Laser Safety
The Spidar utilizes a 1550nm fiber-laser source.
The Spidar contains a Class 4 laser source, but the product is equipped with all the laser safety means
needed for the assignment as a Class 1M laser product to comply with the IEC/CE 60825-1 standard, as
well as the CDRH (FDA) Title 21 CFR 1040.10 standard.
Class 1M is eye-safe for naked eye, but may be hazardous if using optical viewing instruments, such an
eye loupes or binocular. Therefore, the product carry a Class 1 M label mentioned, "Do not Stare directly
with Optical Instruments".
B. Laser Safety Warnings
C. Laser Safety Requirements
The Spidar laser source classified as class 4, is assembled inside a metal protective housing and an
additional external envelope that is enclosing the Laser beam inside the protective housing. The only
laser beam is the Class 1M Laser beam that is projected by the housing on the top of the product.
D. Electrical Safety
The Spidar input voltage is 24VDC (low voltage with low risk).
The Spidar is designed in full compliance with the European Safety Directive for electrical equipment for
measurement, control and laboratory use EN601010-1:2001.
Never look directly into the Spidar window.
Never look directly into the Spidar window.
Never cover the Spidar window.
Never cover the Spidar window.
Only certified NRG technicians are authorized to open a Spidar
system. The Spidar internal laser is class 4, and therefore is
hazardous to direct eye exposure. Diffused reflections such as
those from paper or other matte surfaces are not harmful.

E. Ergonomic Safety
Please review the following ergonomic safety instructions and warnings.
Input voltage for the Spidar is 24V DC. Use only the Spidar
supplied power cable.
DC input voltage for the Spidar is 24V DC. Use only the
supplied power cable.
Spidar AC/DC power supply installation ONLY to electrician or
certified NRG technician.
Input voltage rating is 110V to 220V AC (50/60 Hz).
Before servicing the Spidar, ensure turning off the power to the
system by switching the ON/OFF key to the OFF position.
Each Spidar has a case to enable safe transportation of the
system. It is recommended that at least two people are used to
lift and carry them due to their size and weight: 75kg (165lb).
