After long storage times or long downtimes without a power supply
(> 12 months), the capacitors in the internal DC link voltage must undergo
controlled recharging, in order to avoid damage. To do this, the DB1 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 cur-
rents, 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 values for the corresponding DC-Link voltage (U
and applied for one hour at least (regeneration time).
• DB1-12...: approx. 324 V DC at U
• DB1-34...: approx. 560 V DC at U
In the unlikely event that you have a problem with your DB1 variable
frequency drive, please contact your local sales office.
When you call, have the following data ready:
• the detailed type description of the variable frequency drive
(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 General Terms and
Conditions (GTC) of Eaton Industries GmbH.
