Charging The Internal Dc Link Capacitors; Service And Warranty - Eaton PowerXL DC1 Manual

1.12 Charging the internal DC link capacitors

1.13 Service and warranty

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 variable frequency drive 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
currents, the inrush current should be limited to approximately 300 to
800 mA (depending on the relevant rating). The variable frequency drive
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 ∼ 1.41 x U ) and applied for one hour at least (regeneration time).
DC e
• DC1-12..., DC1-32...: about 324 V DC at U
• DC1-34...: about 560 V DC at U
￫
Due to the internal voltage doubler circuit, the capacitors in
DC1-1D... variable frequency drives cannot be reformed using
the connection terminals!
Please contact your local sales office.
In the unlikely event that you have a problem with your DC1 variable
frequency drive, please contact your local sales office.
When you call, have the following data ready:
• The exact variable frequency drive part number (see nameplate),
• the date of purchase,
• a detailed description of the problem which has occurred with the
variable frequency drive.
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.
