2.1 Intended Use
The Antenna Extension Kit is an accessory set for SMA inverters: By installing the Antenna Extension
Kit in an SMA inverter with WLAN interface, the inverter's radio range can be optimized within the
WLAN network.
The Antenna Extension Kit must only be installed in the following SMA inverters:
• STP 50-40 (Sunny Tripower CORE1)
• STP 50-JP-40 (Sunny Tripower CORE1-JP)
The inverter still complies with the standard after the product has been installed.
The product must only be used in countries for which it is approved or released by SMA Solar
Technology AG and the grid operator.
The product is suitable for indoor and outdoor use.
Use this product only in accordance with the information provided in the enclosed documentation
and with the locally applicable standards and directives. Any other application may cause
personal injury or property damage.
Alterations to the product, e.g. changes or modifications, are only permitted with the express written
permission of SMA Solar Technology AG. Unauthorized alterations will void guarantee and
warranty claims and in most cases terminate the operating license. SMA Solar Technology AG
shall not be held liable for any damage caused by such changes.
Any use of the product other than that described in the Intended Use section does not qualify as the
intended use.

2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with
the product.
To prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
DANGER
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources on the AC and DC sides as described in the inverter manual. When doing so, note
that even if the DC load-break is switched off, there will be dangerous direct voltage present
in the DC conductors of the inverter.
