1.3 PRELIMINARY RECOMMENDATIONS

DANGER!
Only qualified personnel familiar with the CFW-11 Frequency Inverter and associated equipment
should plan or implement the installation, start-up and subsequent maintenance of this equipment.
These personnel must follow all the safety instructions included in this Manual and/or defined by
1
local regulations.
Failure to comply with these instructions may result in life threatening and/or equipment damage.
NOTE!
For the purposes of this manual, qualified personnel are those trained to be able to:
1. Install, ground, energize and operate the CFW-11 according to this manual and the effective
legal safety procedures.
2. Use protection 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 inverter.
Many components can remain charged with high voltages or remain in movement (fans) even after
that AC power is disconnected or switched off.
Wait at least 10 minutes before handling the equipment to assure a total discharge of the capacitors.
Always connect the equipment frame to the protection earth (PE) at the suitable connection point.
ATTENTION!
Electronic boards have components sensitive to electrostatic discharges. Do not touch directly
on components or connectors. If necessary, touch the grounded metallic frame before or use an
adequate grounded wrist strap.
NOTE!
Frequency Inverter may interfere with other electronic equipment. In order to reduce these effects, take
the precautions recommended in the chapter 3 - Installation and Connections, of the user's manual.
NOTE!
Read the user's manual completely before installing or operating the inverter.
