Transformer con-
nections IN1 / IN2
The temperature of the external medium-voltage transformer can be monitored and eval-
uated via the IN1 and IN2 connections. The inverter then adjusts the power of feeding in
according to the temperature of the medium-voltage transformer.
If a specific temperature is exceeded, the
inverter reduces the power of feeding in
and a warning message is shown on the
display.
The grid power feed operation is not inter-
rupted.
