The "F" means "floating" power bus voltage, because it is not referenced to the chassis. This range is ALWAYS equipped for rear mounting. The motor outputs and the supply inputs are ALWAYS on a terminal bar. The logic inputs - outputs of the X5 rear connector allow the serial connection of the protection signals AMP. READY and POWER READY. All connections are ALWAYS made on the top of the rack (power supply, motors, logics). The "BF/400" rack is to be directly connected to the 400 VAC mains. A progressive loading system is integrated in order to limit the inrush current at power up. A current smoothing reactance coil can be used for improving the current harmonics. But this rack can, of course, also work with an insulation transformer. The whole SMT-BD1-400/15, 30, 45, 60 range is particularly well suited for the "BF/400" rack. The SMT-BD1/400/I amplifiers width is 24 TE. The power supply unit ALWAYS includes the auxiliary supply, the power supply and the braking system. It is mounted on a chassis fixed on the left rack flange. Its width is 12 TE. The braking system is equipped with a safety function indicating its correct operation. This function is called "D/R OK" (braking system OK): it controlls a relay that can be serially used with the "Σ POWER READY" signal of the X5 connector (pins 3 and 4) in order to interrupt the power contactor in case of incorrect operation. The power supply can be equipped with a 70 A or 90 A rectifier bridge. The braking system includes all options D2, Dp and E. Resistor Continuous resistance Peak power OPTION D2 33 Ω on rack flange 280 W 27 KW OPTION dp 33 Ω external 280 W 27 KW OPTION E 2 x 33 Ω = Req = 16,5 Ω 560 W 55 KW The "D2" option is factory mounted and wired on the left rack flange whereas the options "Dp" and "E" require external mounting and wiring. The braking resistor is under high voltage (800 V) and may become very hot. It is mandatory to mount it at a correctly cooled place or outside the cabinet. But, in any case, the resistor housing of D2, Dp and E must be mounted at least 30 cm away from any part that could burst into flame because of the heat radiated by the braking resistor. The "BF/400" rack answers the requirements of the EN 55011 standard regarding the electromagnetic compatibility, with optional input filter for the mains rejection. The common mode filter of the motor output as well as the mains filter of the auxiliary supply are integrated in the rack, as standard. The fan must always be mounted on the top of the rack. Chapter 1 – General description 5 BF RACK / 400 VAC 1.2 – Reference to the standards The SMT-BD1/400/I amplifiers mounted into the BF rack in 400 VAC, which is equipped with the mains filter F-400-70, have been approved for their conformity with the EMC standards: • • EN 55011, Group 1, Class A, regarding radioelectric disturbances CEI 801 - 2 - 3 - 4, regarding the immunity. The tests have been performed by the external laboratory of the SCHAFFNER company, which is approved for its competence regarding EMC. The results of the tests made according to the Low Voltage directive are referenced in the LCIE report n° 413777. Standard for the electrical equipments of industrial machines: EN 60204.1. 1.3 – "CE" mark The racks have been "CE" marked since 1995. 6 Chapter 1 – General description BF RACK / 400 VAC 2 – ORDERING CODE OF THE "BF/400" RACK BF-400 / - A x i s A x i s A x i s 1 2 3 - V 1 axis rack = V01 2 axes rack = V02 3 axes rack = V12 Axis 2 Axis 3 Power supply AXES LOCATION 2 2 spaces (24 TE) NOTE : Decreasing current ratings from left to right.

The ground connection is made by a fastening lug according to the safety standards regarding the grounding. Motor cable Motor cable shield 360° shield connection collar Earth Ø 5 screw Motor screw connector U V W Support module having the chassis as mechanical reference potential 2 Maximum section: 4 mm . Maximum continuous current: 44 Arms. NOTE The conformity with the EMC standards requires the mandatory shielding of the motor cables, with a 360° connection at both ends. The motor cables must not run in the proximity of input command and resolver cables. 6 – 400VAC THREE-PHASE MAINS OPERATION To improve the current harmonics on 400 VAC mains operated items, a reactance sized to match the rack or amplifier current rating can be used. This choke is connected in series with the rack input.. Reactance choke ref.: L-400/25/35/80. The direct mains operation without reactance choke requires an appropriate supply cable section with a factor of 1,5 with regard to the rack rating. The power supply must ALWAYS be three-phase connected via a differential three-phase circuit breaker. EXAMPLE: Type Réfex XC40 + Unit Vigi 300 mA, ref. 20340 (by Merlin Gérin). The circuit breaker sizing is depending on the application or on the rack or amplifier ratings: 10 A = ref. 18134 ; 15 A = ref. 18135 ; 20 A = ref. 18136 ; 25 A = ref. 18137 ; 32 A = ref. 18138 ; 38 A = ref. 18139 (by Merlin Gérin). NOTE Fuses cannot be used on the line input because the blowing of one of the three fuses would reduce the lifetime of the whole equipment. A magnetothermal circuit breaker must be used instead of fuses if not using the recommended differential circuit breaker. The auxiliary supply must ALWAYS be connected to the 230 VAC single-phase mains. The connection to the 230 VAC single-phase mains must made via a phase + neutral circuit breaker: EXAMPLE: Type DPN, curve C, ref. 20743 or DPN N, curve D, ref. 19233 by Merlin Gérin. Chapter 3 – Connections 15 BF RACK / 400 VAC NOTES On the three-phase connection, for the power supply, or the single-phase connection, for the auxiliary supply, all supply must ABSOLUTELY be cut-off to ALL POLES The direct mains connection is more cost effective but it is still possible to use a 400 VAC / 400 VAC insulation transformer (connection similar to the connection diagram with a grounded screen transformer). EMC The motor output is equipped with a common mode choke and the auxiliary supply is also equipped with a mains filter. In order to conform with the EN 55011 standard, group 1, class A, the mains filter for the power is optional and must be mounted before the 400 VAC three-phase rack input and as close as possible to the rack in order to ensure equipotentiality. The BF/400 rack chassis MUST be GROUNDED in order to ensure the user's physical protection in case of mains isolation failure. INFRANOR will withdraw its warranty on any item that does not meet these requirements. 16 Chapter 3 - Connections BF RACK / 400 VAC CONNECTION DIAGRAM K K.1 L1 L2 L3 GND N 400 VAC 1 3 5 N . 1 Aux. relay N 24 V K1 (#) ( ) Power Aux. relay ON 2 Power ON Enable Amp. ready Disable 2 4 Aux.

The curves below show the recordings of the conducted and radiated disturbances according to the EN 55011 standard, group 1, class A, with mains filter BF-400/I. - Mains rejection: curves 8 and 9. - Radiated electrical field: curve 10. MAINS FILTER CONNECTION The mains filter must be connected as close to the BF-400 rack as possible (max. 30 cm). A metallic braiding must connect the filter ground terminal to a fastening screw of the BF-400 rack in order to get the equipotentiality. It is recommended to use the cabinet housing for ensuring the equipotentiality. The current rating must correspond to the rack current rating, that is: - F-400/35 for 35 A - F-400/70 for 70 A. CURVE NR. 8 18 Chapter 3 - Connections BF RACK / 400 VAC CURVE NR. 9 CURVE NR. 10 Chapter 3 – Connections 19 BF RACK / 400 VAC 8 – SPECIAL CONNECTION REQUIREMENTS Wiring and ground connections must be very carefully made. CAUTION Low potential cables MUST NEVER run in the proximity of high potential cables. NC, amplifier, motor and machine housing must be grounded via connections as short as possible. Use the cabinet housing for ensuring the equipotentiality. Use rather braidings than wires, even thick ones. Keep the equipotentiality between NC/amplifier, machine housing and motor. The connectors must be metallic or metallized (according to the CEI 801 standard) and must allow "360°" shield connections. The reference potential is the earth (ground). The input command and the command cables MUST be shielded. The motor cable MUST be shielded and connected at both ends over 360°. Connect the shield to the motor or machine housing, as close to the motor as possible, by means of a metal flange after having removed the paint if the connector is not metallic. The sensor cable must be shielded. The correct sensor wiring is an absolutely necessary condition for the correct operation of the amplifier. If these recommendations are not answered, the described specifications will not be obtained. Further, the wiring will not comply with the EMC requirements and will commit the user's responsibility. The shield connections must be made as follows: The connector housing is metallic or plated and allows an "360" shield connection, according to the CEM - CEI 801 - 2 - 3 - 4 - 5 recommendations.
