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. If you unplug the terminal plate plate with the connected DC conductors from DC-in slot under load, an
electric arc may occur, which can cause an electric shock and burns.
• 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 of the inverter
is switched off, there will be dangerous direct voltage present in the DC conductors on the DC-in connecting
terminal plate in the Connection Unit of the inverter.
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.
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.

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 Explanation
A 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.
