Recommendations For The Wireless Signal Power - ABB UNO-DM-TL-PLUS-US Product Manual

ecommendations for the wireless signal power
The radio signal level between the inverter and the wireless router can be
improved in a number of ways:
1. Find a new position for the router considering the different types of
materials which the radio signal will have to pass through:
Material
Open field
Wood / Glass
Stone / Plywood
Reinforced concrete
Metal
The quality of the RF signal can be assessed during the installation stage
where the signal is displayed in dBm.
The antenna has a dead zone at its tip, which should not be positioned
facing the wireless router, as shown in the figure.
2. Install a wireless signal repeater and place it in an area between the
inverter and the router, trying to make sure that the most critical obstacles
are avoided.
