1.3 PRELIMINARY RECOMMENDATIONS

DANGER!
Always disconnect the main power supply before touching any electrical
device associated with the inverter. Several components may remain charged
with high voltage and/or in movement (fans), even after the AC power supply
has been disconnected or turned off. Wait at least 10 minutes to guarantee
the fully discharge of capacitors. Always connect the equipment frame to the
ground protection (PE).
NOTE!
Frequency inverters may cause interference in other electronic devices. Follow
„
the recommendations listed in
on page
Fully read this manual before installing or operating the inverter.
„
Do not perform a withstand voltage test on any part of the inverter!
DANGER!
Crushing Hazard
In order to ensure safety in load lifting applications, electric and/or mechanical
devices must be installed outside the inverter for protection against accidental
fall of load.
DANGER!
This product was not designed to be used as a safety element. Additional
measures must be taken so as to avoid material and personal damages.
The product was manufactured under strict quality control, however, if installed
in systems where its failure causes risks of material or personal damages,
additional external safety devices must ensure a safety condition in case of a
product failure, preventing accidents.
ATTENTION!
When in operation, electric energy systems - such as transformers, converters,
motors and cables - generate electromagnetic fields (EMF), posing a risk to
people with pacemakers or implants who stay in close proximity to them.
Therefore, those people must stay at least 2 meters away from such equipment.
