Installation 5 INSTALLATION 5.1 Danger information WARNING This equipment carries a dangerously high voltage and has dangerous rotating parts (fans). Ignoring the safety and warning information may result in death, severe personal injury or damage to property. The machine operator is responsible for mounting the power unit, the motor, the transformer and any other equipment in accordance with appropriate safety regulations (e.g.
Installation 5.2 Standardization information Series BUC 6xx are built-in units in the sense of provisional standard EN 50178/VDE 0160/11.94, Section 5.2.6 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.1. They are intended for installation in commercially available control cabinets whose degrees of protection meet the minimum requirements of provisional standard EN 50178/VDE 0160/11.94, Section 5.2.4 (IP 2x, possibly IP4x according to EN 60529/5.1).
Installation Normally, only non-conducting pollutants are produced. When the equipment is out of service, brief conductivity can occur due to condensation. - Overvoltage category III according to IEC 664-1, Table 1 for the air clearances of mains circuits to their environment according to provisional standard EN 50178/VDE 0160/11.94, Section 5.2.16.1. - The rated insulation voltage of the mains circuits for TN and TT systems according to DIN VDE 0100 Part 410/11.83 with a diametric voltage of 3 x 500 V.
Installation 5.3 EMC information General information about converters Modern semiconductor technologies such as MCTs and IGBTs are intended to minimize the power loss in the converter by switching more quickly and, with this, to continually reduce the size of the power section. As a result, when running converters you must meet specific conditions to avoid electromagnetic influences caused by switching operations.
Installation Cabling y To suppress radiated noise outside the converter, you should screen all the connected cabling. Also observe the topics in the section entitled "Screening". Feed/Feed-Back Units BUC 624, 625 Baumüller Nürnberg GmbH 25 5.96024.
Installation y You achieve the lowest possible effective antenna height by routing the cable directly on the ground of the metallic rack. y You should route all lines as close as possible to the conductors of the ground system to reduce the effective loop area for magnetic coupling. y When parallel-routing signal and control lines across power cables, the conductors must be at least 20 cm apart. y Lines of different EMC categories should only cross at an angle of 90°.
Installation y The grounding of reserve wires in cables is mandatory (additional screening, avoidance of capacitively coupled, hazardous contact voltages). Grounding y To meet EMC requirements, the classical star grounding is no longer sufficient to reduce the noise of high frequencies caused by converter operation. Better results can be achieved by a reference surface which must be linked to the units’ ground (e.g.
Installation Screening The screen is effective against magnetic fields if it is connected to frame ground at both ends. y With electrical fields, the screen is effective when it is connected to frame ground at one end. However, in the case of (electrical or magnetic) fields with high frequencies (depending on the length of the line), you must always connect the screen at both ends due to the linkage (electro-magnetic field).
Installation y Proposal for the screen connection Filtering No filters are needed for the converter to function. However, under some circumstances, filters may be needed on the input or the output side to comply with EMC regulations. If you have any queries about filter design, please ask for the description entitled Baumüller Filters for Network Applications, BFN. Filter assembly y Mount the filter directly next to the converter.

Installation NOTE In the 24-V input, the BUC 62x has capacitors; this means that when the 24-V supply switches, absorption currents occur! The 24-V power supply is passed on via connections to the BUS 62x Power modules; this leads to increased current consumption. In the case of continuous operation below 24 V -10% (22.7 V), the cooling power of the internal fan is reduced. Power reduction of the feed unit is available on request.

Commissioning 6 COMMISSIONING 6.1 Danger information WARNING This unit carries a dangerous voltage and contains dangerous rotating parts (fans). Ignoring the safety and warning information may result in death, severe personal injury or damage to property. You are responsible for mounting the power unit, the motor, the line reactor and any other equipment in accordance with appropriate safety regulations (e.g.
Commissioning WARNING Before switching on the drive, you must carefully check the functions of all the higher level safety equipment to prevent injury to people. Faulty drive response During initial commissioning, faulty or uncontrolled motion of the driven machine elements is always possible. At this stage, you should therefore proceed with particular care.
Commissioning 6.2 Operation Switch-on sequence First of all, auxiliary relay D1 must supply power to the charging circuit. After the charging time of between 2 and 10 seconds (depending on the DC link capacitance) has expired, the device switches on the main contactor itself via contact X1:4/5 "Enable main contact". Now the external controller has to switch off the charging circuit from mains with die auxiliary relay D1.
Commissioning 6.3 Voltage/phase failure NOTE This message is not stored. y In the case of a mains failure, the system disables the Ready for use of the Feed/Feed back Unit. y The Feed/Feed back Unit generates the Alert/Disturbance message. y When the mains voltage is restored, the charging circuit must be activated by D1 (see Switch on Sequence). After charging is completed, the Feed/Feed back Unit goes into Ready for use status.
Commissioning y DC link Monitoring The level of the DC link voltage is monitored in the BUC. The system generates a message if the DC link voltage exceeds 840 V. The internal and external Ready for use are disabled. The response of the DC link monitoring is indicated by the red LED "UZK>" and can be reset by means of an external reset.
Commissioning y Ready for Use The external Ready for use closes signal contact X99AB:1,2 when the power unit Ready for use is pending and no monitoring has tripped. At the same time, the system generates internal Ready for use. This signal is evaluated by the devices connected to X99A/X99B. Ready for use isindicated by the green LED "BB int". The Feed/Feed-Back unit is ready for use if none of the before named messages queues.
Maintenance 7 MAINTENANCE WARNING This equipment carries a dangerously high voltage and has dangerous rotating parts (fans). Ignoring the safety and warning information may result in death, severe personal injury or damage to property. You may only carry out maintenance and corrective maintenance work when the unit is deenergized. Do not begin work on the power stage and the connections until you have made sure that the system has been deenergized.
Maintenance 7.2 Environmental conditions If you keep to the environmental conditions during the entire period of storage, you can assume, that the device will not be damaged.
