1.10 Maintenance and inspection
DA1 variable speed starters are maintenance-free, provided that the general
rating data, as well as the technical data for the specific models in use, is
observed. Please note, however, that external influences may affect the
operation and lifespan of a DA1 variable frequency drive.
We therefore recommend that the devices are checked regularly and the
following maintenance measures are carried out at the specified intervals.
Table 2: Recommended maintenance
There are no plans for replacing or repairing individual components of DA1
variable frequency drives.
If an FS2 or FS3 (IP20, IP66) DA1 variable frequency drive is damaged or
ruined by external factors, it will not be possible to repair it.
In the case of frame sizes FS4 to FS8, it may be possible for a qualified and
certified service center to repair it ( Section 1.13, „Service and warranty“).
Dispose of the device according to the applicable environmental laws and
provisions for the disposal of electrical or electronic devices.
1.11 Storage
If the DA1 variable frequency drive is stored before use, suitable ambient
conditions must be ensured at the site of storage:
• Storage temperature: -40 - +60 °C,
• Relative average air humidity: < 95 %, non condensing (EN 50178),
• To prevent damage to the variable speed starter’s internal DC link
capacitors, it is not recommended to store the variable frequency drive
for more than 12 months ( Section 1.12, „Charging the internal DC
link capacitors“).
