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!
The MW500 inverter may interfere in other electronic equipment. To
„
minimize these effects, carefully follow the recommendations of
INSTALLATION AND CONNECTION on page
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.
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.
