2.1 Safety Symbols
The following symbols are used in this guide:
WARNING
Indicates a potentially hazardous situation that could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could result in minor or moderate injury. It can also be used to alert against unsafe practices.
NOTICE
Indicates important information, including situations that can result in damage to equipment or property.
2.2 Quali€ed Personnel
Correct and reliable transport, storage, installation, operation, and maintenance are required for the troublefree and safe operation of the frequency converter. Only quali€ed personnel are allowed to install or operate this equipment.
Quali€ed personnel are de€ned as trained sta‚, who are authorized to install, commission, and maintain equipment, systems, and circuits in accordance with pertinent laws and regulations. Also, the quali€ed personnel must be familiar with the instructions and safety measures described in this installation guide.
2.3 Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation, start-up, and maintenance by qualified personnel can result in death or serious injury.
•Only qualified personnel must perform installation, start-up, and maintenance.
WARNING
UNINTENDED START
When the frequency converter is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage. The motor can start with an external switch, a fieldbus command, an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up Software, or after a cleared fault condition.
To prevent unintended motor start:
•Press [Off/Reset] on the LCP before programming parameters.
•Disconnect the frequency converter from the mains.
•Completely wire and assemble the frequency converter, motor, and any driven equipment before connecting the frequency converter to AC mains, DC supply, or load sharing.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not powered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait the specified time after power has been removed before performing service or repair work can result in death or serious injury.
•Stop the motor.
•Disconnect AC mains and remote DC-link supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
•Disconnect or lock PM motor.
•Wait for the capacitors to discharge fully. The minimum waiting time is specified in the chapter Safety in the operating instructions supplied with the frequency converter.
•Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.
