Choke types The recommended location for the AC choke is the bottom part of the enclosure, where it should be installed close to the rear wall. For a possible later installation of a fuse switch, it may be practical to install the AC choke somewhat to the left. Fasten the choke on an assembly plate or using mounting rails. Figure 4. Installing the AC choke NOTE! An upper support plate must be installed above the choke if the cabinet is transported in a horizontal position. A possible fixed support plate must be equipped with air circulation holes. See Figure 17 on page 21.

9 INSTALLING THE POWER MODULE 9 5. INSTALLING THE POWER MODULE 5.1 Preparing the enclosure To facilitate a possible future replacement of boards as well as other service work, it is recommended that the power module be mounted on rails. Fasten mounting rails to the sides of the cabinet at distances given under F (from the top) and G (from the bottom) in the table below. Leave a space (A) between the module and the walls on both sides for the internal cooling air circulation. A A E B C F D G Figure 5. Preparing the enclosure for the power module The power module should be fastened to the rear side of the enclosure as shown in Figure 6. For this purpose, install two fixing bars on the rear wall of the cabinet at appropriate levels. Note the following dimensions that are essential for placing the power module. All dimensions in mm: A B C D E F G 50* (290) (590) Table 7. A = Minimum distance to the side walls or adjacent components. * = Note that the two cabinets, in which the modules of ATV780C56Y to ATV 780C71Y are installed, require no clearance between them. B = Minimum distance from the top of the cabinet; This space is needed for the power cables (see Figure 9). C = Module height 5

10 10 INSTALLING THE POWER MODULE D = Minimum distance from the bottom of the enclosure if the AC choke is installed at the bottom of the enclosure. If the choke is installed in another location, the distance must not, however, be smaller than what is given in parentheses E = Minimum distance from the cabinet door. F = Minimum distance from the mounting rails to top of the cabinet. G = Minimum distance from the mounting rails to the bottom of the cabinet. If the choke is installed in another location, the distance must not, however, be smaller than what is given in parentheses See also the dimensional drawings in chapter Mounting the power module NOTE! If the space around the power module is narrow, lead the internal power cables along the wall and fasten them in brackets before mounting the power module. See chapter 6. Fasten the power module to the rear wall of the enclosure utilising the fixing holes in the frame. Figure 6. Mounting the power module NOTE! If the power module is installed before the AC choke, the centre of gravity is very high at this stage. Make certain that the enclosure does not fall over during the assembly.

11 INSTALLING THE POWER MODULE Grounding the power module Install a PE rail, for instance at the bottom front of the enclosure. Connect a grounding cable from the grounding connector at the lower right hand side of the power module frame to the PE rail of the enclosure. Use a copper grounding cable with a cross-sectional area of at least 35 mm 2 per power module, which obeys the local regulations for grounding cables. See Figure 7 on page 11. NOTE! The PE rail must be connected to external ground at the installation site according to local regulations. Grounding cable PE rail Figure 7. Grounding the power module 5

16 16 PREPARING FOR EXTERNAL POWER CONNECTIONS 8. PREPARING FOR EXTERNAL POWER CONNECTIONS 8.1 Installing mounting plate and input terminals For further installation of other devices (breakers, fuses, EMC grounding), it is recommended that an installation plate be mounted in front of the AC choke, leaving the bottom part open for air circulation. Install input terminals on the plate and connect them to the input terminals (the uppermost terminals) of the AC choke using busbars or flexible busbars according to Table 10. Voltage range V Product ATV780C20Y... ATV780C31Y ATV780C35Y...ATV780C50Y ATV780C56Y...ATV780C71Y Table 10. Copper busbars Cu busbar, size 30*6 mm 40*6 mm 2 pcs 30*6 mm L1 L2 L3 Figure 12.

17 PREPARING FOR EXTERNAL POWER CONNECTIONS Installing fuses The power module contains no internal fuses. To protect the device and allow the installation of a main switch in the enclosure, it is recommended that a fuse switch be installed. Use ar type fuses according to Table 11, and install them in the same enclosure as the frequency converter, or in another enclosure in the immediate vicinity.

Fuse recommendations 8.3 Installing EMC grounding The output cables to the motor must be 360 o EMC earthed. The EMC grounding clamps can, for instance, be installed on the mounting plate in front of the AC choke as shown in the figure below. The EMC grounding clamps must be suited to the output cable diameter to give a 360 o contact with the cables. Refer to the User's Manual for output cable diameters. EMC grounding PE rail Cable fixing clamps Figure 13. Installing EMC grounding 7

18 18 PREPARING FOR EXTERNAL POWER CONNECTIONS 8.4 Understanding the power unit topology Figure 14 shows the principles for mains and motor connections of ATV780C20 to ATV780C71. ATV78C50 has double input devices and requires an even number of supply cables but an uneven number of motor cables can be used. ATV780C56 to ATV780C71 consist of two power modules and require an even number of supply and motor cables. See Figure 14 and Table 12. M M M Note! Min cable length 5m ATV780C20Y to ATV780C45Y Single input Single output ATV780C50Y Double input* Single output ATV780C56Y to ATV780C71Y Double input Double output Figure 14. Topology of mechanical sizes FR10 FR Connecting input and output power Mains and motor cables The mains cables are connected to terminals L1, L2 and L3 and the motor cables to terminals marked with U, V and W, see Figure 8. In ATV780C50Y to ATV780C71Y an even number of input cables is required. In converters consisting of double power modules (FR12) an even number of input cables and an even number of motor cables is needed. WARNING In types with double inputs (ATV780C50Y to ATV780C71Y) or outputs (ATV780C56Y to ATV780C71Y) is it very important that the same cable dimensions, type and routing is used for all cables. In case the cabling between the converter modules is not symmetrical, unequal load inside converter might reduce loadability or even damage the converter. WARNING In units with double motor outputs the motor cables must not be connected together in the converter end. Always connect the parallel motor cables together in the motor end only. The minimum motor cable length is 5m. The output cables to the motor must be 360 o EMC earthed. The EMC grounding clamps can, for instance, be installed on the mounting plate in front of the AC choke as shown in the figure below. The EMC grounding clamps must be suited to the output cable diameter to give a 360 o contact with the cables. 7

19 PREPARING FOR EXTERNAL POWER CONNECTIONS 19 As a rule of thumb, cables and the fuses can be dimensioned according to the frequency converter nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds the output current. Table 12 shows the minimum dimensions of Cu- and Al-cables and the recommended ar fuse sizes. If the motor temperature protection of the drive (see the Programming Manual, on the CD) is used as an overload protection, the cable should be chosen accordingly. If three or more cables are used in parallel (per block) in bigger units each cable requires a separate overload protection.

20 20 Control of main air flow 9. CONTROL OF MAIN AIR FLOW CAUTION! It is of utmost importance for the operation and lifetime of the frequency converter that the enclosure is well ventilated to keep the temperature below the maximum operating temperature. Repeated overheating will shorten the lifetime of the converter. 9.1 Arranging ventilation of the enclosure The enclosure door must be provided with air gaps for air intake. To achieve sufficient cooling inside the cabinet, the dimensions for the total area of free openings for incoming air given in Table 9 must be followed. For instance, there could be two screened gaps as presented in Figure 0 (Manufacturer s recommendation). This layout ensures a sufficient air flow to the module fans as well as cooling of the additional components. 2 Air outlet gaps must be situated on top of the cabinet. The minimum effective air outlet area per converter frame is given in Table 9.The cooling arrangements inside the cabinet must be such that they prevent hot output air from mixing with the incoming fresh air (see page 21 below). The ventilation gaps must fulfil the requirements set by the selected IP class. The examples in this manual apply to protection class IP21. During operation, air is sucked in and circulated by a fan blower at the bottom of the power unit. If the power unit is placed in the upper part of the cabinet, the fan blower will be in the mid of the cabinet, at the height of the upper ventilation grid. 1 FR10 FR11 FR12 1 2x13 dm 2 2x20 dm 2 2x26 dm dm 2 11 dm 2 14 dm 2 Table 13. Ventilation requirements Figure 15 Ventilation arrangements on the cabinet 7

21 Control of main air flow Steering the internal air flow Cooling air must be sucked in through the ventilation gaps on the door and blown out at the top of the enclosure. To steer the hot air from the power unit to the outlet at the top of the enclosure and prevent it from circulating back to the fan blower, use either of the following arrangements: A. Install a closed air duct from the power unit to the outlet on top of the enclosure (A in the figure below). B. Install shields in the gaps between the power unit and the cabinet walls (B in the figure below). Place the shields above the air outlet gaps at the sides of the module. In ATV780C56Y to ATV780C71Y, close the opposing gaps in the upper part of the cabinets with a sheet metal plate to ensure proper cooling. A Air duct B Sheet metal Shields Touch protection cover Choke upper support Mesh type touch protection Figure 17. Arrangements for steering hot air to the outlet at the top of the cabinet 7

22 22 Control of main air flow NOTE! NOTE! To allow free air circulation, the touch cover at the bottom of the cabinet must be of type meshed sheet metal screen. For the same reason, the busbar touch protection cover and the choke upper support must be equipped with holes. See Figure 17. If a flat roof is used, mount a V-shaped air guide on the underside of the roof to direct the air flow horizontally. See Figure 18. Figure 18. Roof structure seen from the side 9.3 Heat dissipation The efficiency of the frequency converter is a function of switching frequency, operating frequency and load (see User s manual). Based on this information, heat dissipation can be calculated at a certain operating point. For most cases the following general formula based on frequency converter load can be used to estimate the heat dissipation of the power module: P [ kw ] Pmot [ kw ]* loss = The following table shows the heat dissipation from the AC choke.
