1 Information on this Document
1.1 Validity
This document is valid for the communication module PC-KP20.BG1 including the corresponding housing.
You will find the type designation on the type label on top of the device.
1.2 Purpose
The purpose of this document is to summarize all for FCC and IC certification relevant technical information
of the PC-KP20 as well as FCC and IC Compliance Information intended for the end user of the host prod-
uct.
2 PC-KP20 Board
The intended use of the PC-KP20 is the integration as the central communication unit into solar inverters or
similar devices (e.g. battery inverter), designed and manufactured by SMA Solar Technology AG. The use of
this module by other manufacturers beside the SMA Solar Technology AG and affiliated companies (herein-
after referred as SMA Solar Technology AG) is not permitted. The PC-KP20 will be attached to the power
unit where it will be supplied and communicates with the processor of the power unit.
For the wireless communication the PC-KP20 provides an IEEE802.11b/g/n for the 2.4 GHz band. This
interface provides:
1x internal antenna for receiving and transmitting

1x external special antenna socket (SMB) for attaching an antenna kit which will be orderable at
SMA Solar Technology AG or its retailers. Operation with other antennas than those specified by
SMA Solar Technology AG for the use with PC-KP20 is not permitted.

3 FCC and IC Compliance Information
This device complies with Part 15 of the FCC Rules and with Industry Canada licence-exempt RSS stand-
ard(s). Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired oper-
ation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est sus-
ceptible d'en compromettre le fonctionnement.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pur-
suant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harm-
ful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connect-
ed.
Consult the dealer or an experienced radio/ TV technician for help.
Changes or modifications made to this equipment not expressly approved by SMA Solar Technology AG
may void the FCC authorization to operate this equipment.
Operation with other antennas than those delivered by SMA Solar Technology AG for the use with inverters
including the module PC-KP20 is not permitted.
RF Exposure Statement
Radiofrequency Radiation Exposure Information:
This equipment complies with FCC radiation limits set forth for an uncontrolled environment. This equipment
should be installed and operated with minimum distance of 8 in. (20 cm) between the radiator and your
body.
