2 Safety SMA Solar Technology America LLC 2 Safety 2.1 Intended Use The Antenna Extension Kit is an accessory set for one SMA inverter and optimizes the SMA inverter’s WLAN radio range. The inverter still complies with the standard after the product has been installed. 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.
2 Safety SMA Solar Technology America LLC Damage to seals on the enclosure lids in subfreezing conditions If you open the enclosure lid of the Connection Unit when temperatures are below freezing, the enclosure lid seal could be damaged. As a result, moisture can get into the Connection Unit. • Only open the enclosure lid of the Connection Unit if the ambient temperature is at least 0°C (32°F) and there is no frost.

4 Mounting SMA Solar Technology America LLC The mounting location of the antenna is crucial for the quality of the wireless connection. Radio waves are emitted in circles from the longitudinal side of the antenna. A circular dead spot begins at the tip of the antenna. If you place the receiver in this dead spot, the receiver cannot receive any radio waves from the antenna.
4 Mounting SMA Solar Technology America LLC Procedure: 1. Danger to life due to high voltages of the PV array When exposed to sunlight, the PV array generates dangerous direct voltage. Touching the DC conductors can lead to lethal electric shocks. Even if the DC load-break switch of the inverter is in the O, position, there will be dangerous direct voltage present in the DC conductors and on the DC-in connecting terminal plate in the Connection Unit of the inverter.
4 Mounting SMA Solar Technology America LLC • Press the multi-hole seal out of the cable gland from the inside. • Route the antenna cable with the cable end with the plug through the swivel nut and the desired hole of the multihole seal. • Push the multi-hole seal along with the antenna cable back into the cable gland. Ensure that any unused openings of the multi-hole seal are sealed with sealing plugs. • Screw the swivel nut of the cable gland on loosely.
4 Mounting SMA Solar Technology America LLC • Lead the antenna cable plug from the antenna bracket’s slot. In doing so, make sure that the washer and the counter nut are on the outside of the antenna bracket and that the antenna cable is not kinked or twisted. • Tighten the counter nut. • Hand-tighten the antenna on the antenna extension cable plug. 6. Danger to life due to electric shock from touching an ungrounded product Touching an ungrounded product can cause a lethal electric shock.
5 Troubleshooting SMA Solar Technology America LLC 5 Troubleshooting Problem Cause and corrective measure The radio range has not improved despite the antenna. The problem can be caused by one of the following: • The inverter has not recognized the antenna automatically. • The antenna is not installed correctly or an unapproved antenna has been used. • The receiver is placed in the dead spot.
6 Decommissioning 6 SMA Solar Technology America LLC Decommissioning 6.1 Removing the Antenna Required tools: ☐ Long-nosed pliers Procedure: 1. Danger to life due to high voltages of the PV array When exposed to sunlight, the PV array generates dangerous direct voltage. Touching the DC conductors can lead to lethal electric shocks.
