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 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 and secure it against reconnection (see the inverter manual).
• Do not remove the DC cable from the connecting terminal plate.
• Do not disconnect the connecting terminal plate with its connected DC cables.
Danger to life due to electric shock from touching an ungrounded product
Touching an ungrounded product can cause a lethal electric shock.
• Ensure that the product is integrated in the existing overvoltage protection.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.

2 Safety
Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other devices (e.g., pacemakers) due to electromagnetic interference.
• Persons must not remain closer than 20 cm (8 in) to the antenna for long periods of time.
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product through electrostatic discharge.
• Ground yourself before touching any component.
2.3
Supported Products
The Antenna Extension Kit must only be installed in the following SMA inverters:
• Sunny Boy 5.0 (SB 5.0-1SP-US-40)
• Sunny Boy 6.0 (SB 6.0-1SP-US-40)

Installation Manual AntExt-Kit-IA-US_en-10 11
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.
Figure 3: Radio waves emitting from the antenna
Position
A
Explanation
Dead spot
Requirements for the mounting location:
☐ An antenna cable length of 3 m (9.8 ft) must be observed. The antenna cable must not be extended.
☐ The antenna cable must be placed in such a way that the minimum bending radius of 35 mm (1.38 in) is maintained.
☐ The receiver must not be in the dead spot of the antenna.
4.2
Mounting the Antenna
Damage to the inverter due to moisture ingress
Moisture penetration can damage the inverter and impair its functionality.
• Never open the inverter when it is raining or snowing, or the humidity is over 95%.
Electrical installations
All electrical installations must be carried out in accordance with the local standards and the National Electrical

• Do not remove the DC cable from the connecting terminal plate.
• Do not disconnect the connecting terminal plate with its connected DC cables.
2. Attaching the cable gland on the inverter:
• Push the sealing plug from the inside out of the second hole from the left in the inverter enclosure and retain it for future decommissioning.
• Unscrew the counter nut from the supplied cable gland.
• Screw the cable gland with the counter nut on the inverter enclosure opening.
3. Connecting the antenna cable plug:
• Unscrew the swivel nut from the cable gland.

• Press the multi-hole seal out of the cable gland from the inside.
SMA Solar Technology America LLC
• 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.
• Remove the protective cover of pin connector ANT. on the communication assembly, if present.
• Insert the plug of the antenna cable into pin connector ANT. on the communication assembly until it snaps
into place. Observe the prescribed cable route (see Section 4.1, page 11).
• Fasten the swivel nut on the cable gland hand-tight. This will secure the antenna cable.
4. Installing the antenna bracket:
• Considering the dead spot of the antenna, move the antenna bracket to the desired position on the wall and hold it firmly.
• Mark positions of drill holes if necessary and drill two holes with 6 mm (0.24 in) diameter each at the marked points and insert screw anchors.
• Attach the antenna bracket to the wall with the screws.
5. Attaching the antenna cable and the antenna to the antenna bracket:
• On the antenna cable, unscrew the counter nut approx.
5 mm (0.2 in) from the plug.

5 Troubleshooting
SMA Solar Technology America LLC
5 Troubleshooting
Problem
The radio range has not improved despite the antenna.
Cause and corrective measure
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.
Corrective measures:
• Ensure that the antenna has been recognized by the inverter:
– Access the web server of the inverter and log in as installer.
– Select Instantaneous values > System Configuration > WLAN >
Antenna Type.
– Check whether the value External Antenna is set.
If the value External Antenna is not set, set the antenna type (see inverter user manual).
• Ensure that the antenna of type “EXTANT-US-40” is installed correctly and that only the supplied antenna cable was used.
• Ensure that the receiver is not placed in the dead spot (see Section 4.1
"Mounting Position and Cable Route", page 11).
