1.11 Charging the internal DC link capacitors
After extended storage times or extended downtimes during which no
power is supplied (> 12 months), the capacitors in the internal DC link must
be recharged in a controlled manner in order to prevent damage. To do this,
the DC1 frequency inverter must be supplied with power, with a controlled
DC power supply unit, via two mains connection terminals (e.g. L1 and L2).
In order to prevent the capacitors from having excessively high leakage cur-
rents, the inrush current should be limited to approximately 300 to 800 mA
(depending on the relevant rating). The frequency inverter must not be
enabled during this time (i.e. no start signal). After this, the DC voltage must
be set to the magnitudes for the corresponding DC link voltage
(U
DC
∼ 1.41 x U
e
) and applied for one hour at least (regeneration time).
• DC1-S2…, DC1-12…, DC1-32…: about 324 V DC at U
e
= 230 V AC.
• DC1-34…: about 560 V DC at U
e
= 400 V AC.
1.12 Service and warranty
In the unlikely event that you have a problem with your DC1 frequency
inverter, please contact your local sales office.
When you call, have the following data ready:
• The exact frequency inverter part number (see nameplate),
• the date of purchase,
• a detailed description of the problem which has occurred with the
frequency inverter.
If some of the information printed on the rating plate is not legible, please
state only the data which are clearly legible.
Information concerning the guarantee can be found in the Terms and
Conditions Eaton Industries GmbH.

Due to the internal voltage doubler, the capacitors in
DC1-1D…frequency inverters cannot be regenerated using the
connection terminals!
