S
6 – conductor connection with additional connection of the power supply at the DC
link:
– for this operating mode, terminals 2U1, 2V1 and 2W1 of the power supply
must be supplied with the line supply voltage between the series reactor and I/R,
otherwise the power supply will be destroyed! This is also valid for the monitoring modules!
S
Monitoring module with line supply connection and additional connection of the power sup-
ply to the DC link:
– for this operating mode, terminals 2U1, 2V1 and 2W1 of the power supply
must be supplied with the line supply voltage between the series reactor and I/R,
as otherwise the power supply will be destroyed.
– terminal 63 must be switched via the ready relay of the I/R
in order to prevent the module, to the right of the monitoring module,
starting during pre–charging.
If a line supply fault is displayed or if the yellow LED is dark, the overvoltage limiting module
must be checked.
Procedure:
1.
Power–down the drive converter (into a no–voltage condition)
2.
Remove the overvoltage limiting module and insert connector X181 on the NE module.
If the NE module functions, then the overvoltage limiting module is defect and must be
replaced.
Otherwise, check the line supply and if required, also the NE module/drive group.
Note
In this way, operation can be continued, but without overvoltage protection.
3.
Insert the overvoltage limiting module 566018.9415.00 up to its end stop, and insert
connector X181 on the overvoltage limiting module.
