•The VLT® Operating Instructions provide the necessary information for getting the frequency converter up and running.
•The VLT® Design Guide provides detailed information about capabilities and functionality to design motor control systems.
•The VLT® Programming Guide provides greater detail on working with parameters and many application examples.
•The VLT® DeviceNet MCA 104 Installation Guide provides information about installing the DeviceNet and troubleshooting.
•The VLT® DeviceNet MCA 104 Programming Guide provides information about con€guring the system, controlling the frequency converter, parameter access, programming, troubleshooting, as well as some typical application examples.
Supplementary publications and manuals are available from Danfoss. See www.danfoss.com/BusinessAreas/DrivesSolutions/Documentations/VLT+Technical+Documentation.htm for listings.
DeviceNet is a low-level network that standardises communications between industrial devices (sensors, limit switches, motor controls) and high-level devices (controllers). DeviceNet systems can be con€gured to operate in a master-follower or a distributed control architecture using peer-to-peer communication.
The DeviceNet interface is designed to communicate with any master abiding by the DeviceNet standard.
VLT® DeviceNet MCA 104 is intended for use with:
•VLT® HVAC Drive FC 102
•VLT® AQUA Drive FC 202

2.1 Safety Symbols
The following symbols are used in this manual:
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 authorised to install, commission, and maintain equipment, systems, and circuits in accordance with pertinent laws and regulations. Additionally, the quali€ed personnel must be familiar with the instructions and safety measures described in these operating instructions.
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.
•Installation, start-up, and maintenance must be performed by qualified personnel only.
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:
•Disconnect the frequency converter from the mains.
•Press [Off/Reset] on the LCP before programming parameters.
•The frequency converter, motor, and any driven equipment must be fully wired and assembled when the frequency converter is connected to AC mains, DC supply, or load sharing.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors that can remain charged even when the frequency converter is not powered. 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 the AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
•Disconnect or lock the PM motor.
•Wait for the capacitors to discharge fully before performing any service or repair work. The duration of waiting time is specified in the relevant frequency converter operating instructions, Chapter 2 Safety.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the frequency converter properly can result in death or serious injury.
•Ensure the correct grounding of the equipment by a certified electrical installer.
