Problem Cause and corrective measure
The radio range has not im-
proved 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.
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12).
