SFD系列气动滤波器操作手册说明书
MaintenanceWarningSelection1. Thoroughly and carefully check the purpose of use, required specifications and operatingconditions then select a model with the appropriate specifications.2. Contact SMC beforehand when the product will be used in applications such as a caisson shieldand for breathing and/or medical treatment that affects the human body either directly or indirectly.Mounting1. Operation ManualRead and understand this Operation Manual carefully before mounting and using the productand keep it available for future reference. 2. FlushingFlush and clean the piping before connecting it to the product. If the piping has dust or other contaminants the product may fail or break. Also, ensure that all required mounting parts are firmly fixed before using the product.3. Use tube fittings with resin threads for the piping to the IN and OUT ports. If a fitting with metalthreads is used it may damage the ports. (Only for SFD100)4. Follow directions for the one-touch fitting to connect tubing to the one-touch fitting at the IN andOUT ports.5． Check the flow direction for the tubing indicated by an arrow. Connecting the tubing incorrectlymay damage the element.Installation1. The element may lose its given performance if the pressure difference (pressure drop) betweenthe primary pressure and secondary pressure exceeds 0.1MPa.2. Design your system to allow this product to be mounted in a place without vibrations, which cancause the pressure difference to exceed 0.1MPa.3. Beware of dust from air equipment mounted at the secondary side. If such equipment is mountedthere it may generate dustand decrease the cleanliness of the product. Check the mounting position of the air equipment.4. Set the air-flow capacity with an initial pressure drop of 0.03MPa or less. If the initial pressuredrop exceeds the required value the flow over the rated value will clog the element, which may shorten the product’s life span.5. Determine the appropriate model by assessing the maximum consumption flow rate. When usingcompressed air for an air blow application, calculate the maximum volume of air that will be consumed before selecting the SFD series product size.6． Generally compressed air could contain the following particle contaminants:・Moisture (drain)･Dust sucked from ambient air・Deteriorated oil discharged from compressor・Solid foreign matter such as rust and oil in the piping1) The SFD series is not available for compressed air containing a liquid such as water and oil. 2） Install a dryer, mist separator, micro mist separator, super mist separator, odor removal filter, etc. for the air source used for the SFD series.Piping1. The filter was packed in anti-static closing double packaging in a clean room and the innerpackage should be removed in a clean environment (clean room, etc.).2. For the piping, apply a wrench to two chamfered flats or width-across flats on the IN or OUT side to prevent the product housing from rotating.3. Use the following torque specifications to screw fittings into the product.4. Flush (air blow) the product when the filter is used for the first time or has been replaced. When connecting piping and other fittings flush before first use or when replacing parts to reduce the effect of dust and other contaminants. Also flush the line to eliminate contaminants that may result from installing the pipe line. Be sure to flush the line before actually running the system.1. Follow the procedure described in this manual to replace the element. When the element isreplaced incorrectly it may cause damage and failure to equipment and the machine. 2. Exhaust the air supply completely to release all pressure in the product.3. When the element comes to the end of its life immediately replace it with a new filter orreplacement element (cartridge type). -When to replace the element- ・After one year of operation.・The pressure drop has reached 0.1MPa even before a year elapses.4． Do not disconnect and replace the one-touch fitting.EnvironmentWarningWarning1.Do not use the product in the following environments, which could cause failure.･In or near a place that may be exposed to a corrosive gas, organic solvent or chemicals. ･A place exposed to water, steam or oil. Direct sunlight (ultraviolet) and high temperatures that may deteriorate resin.･A place with a heat source and poor ventilation. (Shade the heat source with heating insulation.)･A place exposed to impact and vibration.･A place exposed to excessive humidity and dust.3. How to mount・Check which side is IN and OUT before connecting.The direction of IN and OUT must follow the arrow marking on the product housing. Arrow marking OUT IN 2.When air blowing, be careful not to contaminate a work piece with entrained ambient air. If air blowing with compressed air the air emitted from a blow nozzle may entrain foreign matter (solid and/or liquid) from the ambient air and attach it to the work piece. Check the ambient environment.1. Description and Function of Each Part・Ensure that each sealing part does not leak.*The figure shows SFD100-C08. ・Keep a space on the cover (at the IN side) to remove the element for maintenance. ・Follow the instructions for the one-touch fitting to connect and disconnect tubing.Warning4. How to replace the elementThe SFD200 element can be replaced. Follow the procedure shown below to replace it.The SFD100 element cannot be disassembled or replaced. It is therefore necessary to replace the entire housing to replace the element. «Reference for the replacement of element»Refer to the following pressure loss value to replace the element.Referential pressure loss for the replacement of element: 0.1MPa (initial pressure loss: 0.03MPa ）«How to replace the element»«Element for replacement»Applicable size Part numberIncludingSFD200 SFD-EL200Element + O-ring (3 pcs)Thread size Material torque (N ･m)Resin 2 to 3 Rc1/4Metal 12 to 141)Stop the operation ・Stop the operation of the product and release the internal pressure.2)Remove the cover・Remove the nut and pull out the tie rod. ・Pull out the cover (1) from the elementand remove the rod cover.・Pull out the element from the cover (2). ・Eliminate dust attached to the inside of the case by air blowing.（Ensure there is no damage on the O-ring.）3)Mount the element・Mount a new element on the cover and return the rod cover.4)Mount the rod cover・Line up the flange on the rod cover with the matching socket on the cover, bottom out the rod cover, insert the tie rod, replace the nuts and tighten.Ensure that the cover cannot be pulled out. ・Mount the plain washer to the tie rod which the bracket does not pass.5)Start the operation・Follow the procedure described in “3．How to mount” to start the operation.WarningNut Cover 2 Element Cover socket Plain washer。

概述
1. 概述
变频器向电机提供的电压不是稳定变化的交流电压，而是脉冲式直流电压。同电网供电的情况一样，三相电 压的和并不为零，从而使电机线圈与地面之间存在共模电压。

注：专业人员是指在安装和/或调试功率传动系统方面（包括 EMC 方面）拥有必要的技术的人员或机构。
EMC 等级 L：符合类别 3 的要求：额定电压低于 1000V 的 PDS，适用于第二环境，不适用于第一环境。
EMC 等级 N：符合类别 4 的要求：额定电压大于等于 1000V 或额定电流大于等于 400 A 的 PDS，适用于第 二环境，不适用于第一环境。注意在这种情况下标准的满足要具体情况具体对待。
2.4 共模滤波器 ............................................................................................................................................. 23
发送到电机的脉冲波非常陡峭，电压变化比（dU/dt）可以达到几个 kV/us。空载时 IGBT 将以大概 6 – 8 kV/us 的速度进行转换，当电机电缆与电机连接时速度会降到 2 kV/us。这些陡脉冲引起的电压对电机的绝缘 可能会产生危险。
高开关速度引起 EMC 影响，在电连接电缆中起辐射干扰与干扰电流的作用。辐射干扰通常通过变频器的金 属外壳并通过删掉屏蔽电缆接地，不会在环境中产生任何问题。为达到电磁兼容的效果，必须过滤掉电耦合 干扰。Vacon NX 范围的变频器装有内部滤波器从而满足传动标准的要求（尤其是 IEC 61800-3:2004），但在 某些情况下，需要使用附加的滤波器。对于 Vacon NX 系列变频器来说，输入滤波器与输出滤波器都可以使 用。另外，也要求对变频器进行保护，防止电网中的过电压变化，因此，在输入侧可以安装射频滤波器，在 输出侧可安装 dU/dt 滤波器或正弦滤波器。
注意滤波器 RFI-0012 -5-5 到 RFI 0061-5-5 适用于直接安装在相应的变频器内。所有其它的滤波器都为活动 式，必须单独与变频器连接。

滤波器必须正确安装与接地。
目前暂无任何标准适用于IT电网（浮动电路）。EMC代码T显示变频器与变频器模块都有极小的接 地电容以使其适用于IT电网。需要使用较小的电容，因为较大的电容会导致接地电路监测回路失 效。推荐使用Bender制造的监控器。
Vacon NX 变频器符合 EN 61800-3; 2004 的抗干扰要求，以第二环境作为标准。
