1.10 Maintenance and inspection
DC1 series variable frequency drives will be maintenance-free as long as the
general rated operational data (see annex) is adhered to and the specific
technical data (see annex) for the corresponding ratings is taken into account.
Please note, however, that external influences may affect the operation and
lifespan of a DC1 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 for DC1 variable frequency drives
There are no plans for replacing or repairing individual components of DC1
variable frequency drives!
If the DC1 variable frequency drive is damaged by external influences, repair
is not possible.
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 DC1 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 frequency drive’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“).
