Long-term storage
After one year at the latest, the frequency inverter must be connected to the
mains supply for 60 minutes. In addition, the fail-safe input (safe pulse block)
must be supplied with voltage ´(24V) or must be operated in its start-up
configuration. This cycle must be maintained for the storage period.
EMC
When using wiring that conforms to EMC requirements, as per BU 0500 DE, the
thresholds can be observed up to a line length of 20 m between the safety
switching device and the inverter.
