 Date of Evaluation:                Monday, January 15, 2018

Information Provided by the Party Requesting the Evaluation

 Functional Description of the Equipment:
 The 9630-9110 is a radio module intended for use in the SEL Wireless Line Sensor System for overhead
 distribution circuits. This system includes sensors that attach to overhead power conductors and wirelessly
 transmit data to concentrators. The system provides fault detection and accurate load data to a centralized
 location for simple integration into a SCADA or outage management system (OMS). The line sensors and
 concentrator communicate via a purpose-built wireless protocol optimized for fault monitoring applications.
 The 9630-9110 operates in the license-free 915 MHz industrial, scientific, and medical (ISM) band.

 Objective:
 To demonstrate compliance with FCC requirements for RF exposure for 2.1091 mobile/fixed devices

MAXIMUM PERMISSIBLE EXPOSURE
(MPE)                                                                                                        EXRPT.2017.10.02




OVERVIEW

Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE
limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since
exposures are assumed to occur at distances of 20 cm or more from persons. ANSI C95.1:2005 + Amd 1:2010
specifies a minimum separation distance of 20 cm for performing reliable field measurements to determine
adherence to MPE limits. If the minimum separation distance between a transmitter and nearby persons is more
than 20 cm under normal operating conditions, compliance with MPE limits may be determined at such distance
from the transmitter. When applicable, operation instructions and prominent warning labels may be used to alert
the exposed persons to maintain a specified distance from the transmitter or to limit their exposure durations
and usage conditions to ensure compliance. If the use of warning labels on a transmitter is not effective or
desirable, the alternative of performing SAR evaluation with the device at its closest range to persons under
normal operating conditions may be used. The field strength and power density limits adopted by the FCC are
based on whole-body averaged exposure and the assumption of RF field levels relate most accurately to
estimating whole-body averaged SAR. This means some local values of exposures exceeding the stated field
strength and power density limits may not necessarily imply non-compliance if the spatial average of spatially
averaged RF fields over the exposed portions of a person’s body does not exceed the limits.

COMPLIANCE WITH FCC 2.1091

 “Mobile devices that operate in the Cellular Radiotelephone Service, the Personal Communications Services,
the Satellite Communications Services, the General Wireless Communications Service, the Wireless
Communications Service, the Maritime Services and the Specialized Mobile Radio Service authorized under
subpart H of part 22 of this chapter, parts 24, 25, 26 and 27 of this chapter, part 80 of this chapter (ship earth
stations devices only) and part 90 of this chapter are subject to routine environmental evaluation for RF
exposure prior to equipment authorization or use if they operate at frequencies of 1.5 GHz or below and their
effective radiated power (ERP) is 1.5 watts or more, or if they operate at frequencies above 1.5 GHz and their
ERP is 3 watts or more. Unlicensed personal communications service devices, unlicensed millimeter wave
devices and unlicensed NII devices authorized under §§15.253, 15.255, and 15.257, and subparts D and E of
part 15 of this chapter are also subject to routine environmental evaluation for RF exposure prior to equipment
authorization or use if their ERP is 3 watts or more or if they meet the definition of a portable device as specified
in §2.1093(b) requiring evaluation under the provisions of that section. All other mobile and unlicensed
transmitting devices are categorically excluded from routine environmental evaluation for RF exposure prior to
equipment authorization or use, except as specified in §§1.1307(c) and 1.1307(d) of this chapter. Applications
for equipment authorization of mobile and unlicensed transmitting devices subject to routine environmental
evaluation must contain a statement confirming compliance with the limits specified in paragraph (d) of this
section as part of their application.”

The device will only be used with a separation distance between the antenna and the body of the user or
nearby persons as shown in the table below and can therefore be considered a mobile transmitter per
47 CFR 2.1091(b).

COMPLIANCE WITH FCC KDB 447498 D01 General RF Exposure Guidance v06


"KDB 447498 D01 General RF Exposure Guidance v06" provides the procedures, requirements, and
authorization policies for mobile and portable devices.

Devices operating in standalone mobile device exposure conditions may contain a single transmitter or multiple
transmitters that do not transmit simultaneously are covered in section 7.1.

Devices containing multiple transmitters capable of simultaneous transmissions are covered in section 7.2.

ASSESSMENT

The exposure level for the radio is evaluated at a 20 cm distance from the radio’s transmitting antenna using the
general equation:

                                             P *G
                                   S 
                                            4* * R            2


Where: S = power density (mW/cm2)
P = power input to the antenna (mW)
G = numeric power gain relative to an isotropic radiator
R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates)
P*G = EIRP

Solving for S, the maximum power density 20 cm from the transmitting antenna is determined. This level is then
compared to the applicable limit for the transmit frequency. If limits were not met at the 20 cm boundary the
evaluation distance is increased until the limit is met as shown in the table below.

For co-located radios, the ratio of the calculated level to the limit is determined. The ratios for each co-located
radio are summed. If the sum is less than or equal to one, then the device is excluded from testing and is
deemed compliant.

Allan Davis, RF Engineer at Distribution Controls & Sensors - R&D, Schweitzer Engineering Laboratories, Inc.
attests that the minimum spacing between the antenna and the body is 23 cm. Regarding the maximum duty
cycle he explained:

          “I was able to confirm that the 13% duty cycle is indeed the maximum over a 6 minute period. If that
          works we will leave the distance at 23 cm in the manual.”
