Charging The Internal Dc Link Capacitors; Service And Warranty - Eaton PowerXL DA1 Series Installation Manual

1.12 Charging the internal DC link capacitors

1.13 Service and warranty

After long storage times or long down times without a power supply
(> 12 months), the capacitors in the internal DC link mustundergo controlled
recharging, in order to avoid damage. To do this, the DA1 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
• DA1-12..., DA1-32...: approx. 324 V DC at U
• DA1-34...: approx. 560 V DC at U
• DA1-35...: approx. 705 V DC at U
In the unlikely event that you have a problem with your DA1 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 rating plate),
• 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 of Eaton Industries GmbH.
