Preliminary Recommendations - WEG CFW501 V1.8X Programming Manual

Safety Instructions

1.3 PRELIMINARY RECOMMENDATIONS

DANGER!
1
Only qualified personnel, familiar with the CFW501 inverter and related equipment must plan or
perform the installation, commissioning, operation and maintenance of this equipment.
The personnel must follow the safety instructions described in this manual and/or defined by local
standards.
The noncompliance with the safety instructions may result in death risk and/or equipment damage.
NOTE!
For the purposes of this manual, qualified personnel are those trained in order to be able to:
1. Install, ground, power up and operate the CFW501 in accordance with this manual and the safety
legal procedures in force.
2. Use the protective equipment in accordance with the relevant standards.
3. Give first aid.
DANGER!
Always disconnect the general power supply before touching 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 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 of the equipment to the protective
earth (PE) at the proper point for that.
ATTENTION!
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 or use proper
grounding strap.
NOTE!
Frequency inverters may interfere in other electronic equipments. Observe the recommendations of
chapter 3 - Installation and Connection of the user's manual in order to minimize these effects.
Read the user's manual completely before installing or operating this inverter.
NOTE!
The operations to copy the inverter parameters by means of the CFW500-MMF accessory must be
preceded by a power-up cycle. That is, after the modification of one or more parameters, it will be
available for copy on the plug-in module after the next power-up of the CFW501.
