Installation Manual
LED next to the
"Grid-Meter" jack is
out for more than
10 seconds.
Reading head/grid feed-in and purchased electricity meter is not
transmitting data continuously.
Corrective measures:
• Check whether the meter for grid feed-in and purchased electricity
displays a value.
If the grid feed-in and purchased electricity meter displays a value,
the reading head may not be connected correctly or may be
defective:
– Make sure that the plug of the reading head or of the extension
cord has been correctly inserted into the "Grid-Meter" jack.
– Make sure that the plug of the reading head and the plug of the
extension cord have been correctly inserted into the designated
jacks (see Section 6.3.3).
– Make sure that the reading head of the grid feed-in and
purchased electricity meter is aligned correctly. Here, slowly turn
the reading head on the grid feed-in and purchased electricity
meter clockwise until the LED next to the "Grid-Meter" jack starts
flashing (see Section 7).
– If the LED next to the "Grid-Meter" jack does not flash, replace the
reading head.
