NOTE!
For the purposes of this manual, qualified personnel are those trained to be able to:
1. Install, ground, energize and operate the Frequency Inverter according to this manual and the
effective legal safety procedures.
2. Use protective equipment according to the established standards.
3. Give first aid services.
DANGER!
!
Always disconnect the input power before touching any electrical component associated to the
frequency inverter.
Many components may remain loaded with high voltages and/or moving (fans), even after the AC
power supply input is disconnected or turned off.
Wait for at least ten minutes in order to guarantee the full discharge of the capacitors. Always
connect the frame size of the equipment to the protective earth (PE) at the proper point for that.
WARNING!
!
Electronic boards have components sensitive to electrostatic discharge. Do not touch directly the
component parts or connectors.
If necessary, first touch the grounded metallic frame size or use proper grounding strap.
