Maintenance and inspection
PowerXL frequency inverters are maintenance free.
However,external influences may affect the function
and the lifespan of the PowerXL frequency inverter. We
therefore recommend that the devices are checked regularly
and the following maintenance measures are carried out at
thespecifiedintervals.
If the PowerXL frequency inverter is damaged by external
influences, contact Technical Service.

Storage
If the frequency inverter is stored before use, suitable
ambient conditions must be ensured at the site of storage:
•
Storage temperature: –40 °F to 158 °F (–40 °C to 70 °C)
•
Relative average air humidity: <95%, noncondensing
(EN 50178)
•
To prevent damage to the DC link capacitors, storage
times longer than 12 months are not recommended
Charging the internal DC link capacitors
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 PowerXL variable frequency drive must be supplied
with power, with a controlled DC power supply unit, via
two mains DC bus connection terminals. Please consult
thefactory for detailed instructions.
