1.3 PRELIMINARY RECOMMENDATIONS
DANGER!
Always disconnect the general power supply before changing any electric
component associated to the inverter. Many components may remain loaded
with high voltages and/or moving (fans), even after the AC power supply is
disconnected or turned off. Wait for at least ten minutes in order to guarantee
the full discharge of the capacitors. Always connect the grounding point of the
inverter to the protection grounding.
NOTE!
Frequency inverters may interfere in other electronic equipment. Observe the
„
comendatórios of

in order to minimize these effects.
Read the entire manual before installing or operating this inverter.
„
Do not execute any applied withstand voltage test on the inverter!
ATTENTION!
The electronic boards have components sensitive to electrostatic discharges.
Do not touch the components or connectors directly. If necessary, first touch
the grounding point of the inverter, which must be connected to the protection
ground or use a proper grounding strap.
ATTENTION!
Do not touch the frame of the inverter directly. The inverter may be very hot
during and after the operation.
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.
