Caution
As soon as the energy supply is present at the infeed terminals (-X1:U1/V1/W1) of the
Active Line Module, the DC link will be precharged (U
DC link
= U
Supply
x 1.35). An enable,
etc., is not required.
Once the "Enable Pulses" enable signal is also present on the Active Line Module, the
boost converter increases the DC link to the specified setpoint p3510 (e.g. U
DC link
= 600 V
for U
Supply
= 400 V).
Note
The Active Line Module (16 kW, 36 kW) and the Smart Line Module (16 kW, 36 kW)
interfaces are identical.
