Programming Guide provides greater

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.

2 Safety

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 qualied personnel can result in death or serious injury.

Installation, start-up, and maintenance must be

•

performed by qualied 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 eldbus 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 [O/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 specied 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 specied 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 certied electrical installer.
