A16B-1212-087 Compliance with EN 61800-3:2004 + A1:2012 Definitions EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic equipment to operate without problems within an electromagnetic environment. Likewise, the equipment must not disturb or interfere with any other product or system within its locality. First environment includes establishments connected to a low-voltage network which supplies buildings used for domestic purposes. Second environment includes establishments connected to a network not directly supplying domestic premises. Drive of category C1: drive of rated voltage less than 1000 V and intended for use in the first environment. Drive of category C2: drive of rated voltage less than 1000 V and intended to be installed and started up only by an authorised professional when used in the first environment. Drive of category C3: drive of rated voltage less than 1000 V, intended for use in the second environment and not intended for use in the first environment. Category C1 The emission limits are complied with the following provisions: 1. The optional EMC filter is selected according to the ABB documentation and installed as specified in the EMC filter manual. 2. The motor and control cables are selected as specified in this manual. 3. The drive is installed according to the instructions given in this manual. 4. For the maximum motor cable length with 4 kHz switching frequency, refer to Motor cable length on page 93. In a domestic environment, this product can cause radio-frequency inference, in which case supplementary mitigation measures may be required. Category C2 Applicable to ACS380-042x with an internal EMC C2 filter. The emission limits are complied with the following provisions: 1. The motor and control cables are selected as specified in this manual. 2. The drive is installed according to the instructions given in this manual. 3. For the maximum motor cable length with 4 kHz switching frequency, refer to Motor cable length on page 93. 102 Technical data If it is used in a residential or domestic environment, the drive can cause radiofrequency interference. If it is necessary, take measures to prevent interference, in addition to the requirements for the CE compliance. WARNING! Do not install a drive with the internal EMC filter connected on IT (ungrounded). The supply network becomes connected to ground potential through the internal EMC filter capacitors which may cause danger or damage to the drive. To disconnect the EMC filter, refer to EMC filter disconnection on page 59. WARNING! Do not install a drive with internal EMC filter connected on cornergrounded TN systems; otherwise the drive will be damaged. To disconnect the EMC filter, refer to EMC filter disconnection on page 59. Category C3 This is applicable to ACS380-040x-4 drives with an internal EMC C3 filter. The drive complies with the standard with the following provisions: 1. The motor and control cables are selected as specified in this manual. 2. The drive is installed according to the instructions given in this manual. 3. For the maximum motor cable length with 4 kHz switching frequency, refer to Motor cable length on page 93. WARNING! To prevent radio-frequency interference, do not use a category C3 drive on a low-voltage public network which supplies domestic premises. Technical data 103 Category C4 This is applicable to ACS380-040x-1 drives. If the provisions in Category C3 are not met, the requirements of the standard can be met as follows: 1. It is ensured that no excessive emission is propagated to neighboring low-voltage networks. In some cases, the inherent suppression in transformers and cables is sufficient. If in doubt, the supply transformer with static screening between the primary and secondary windings can be used. 2. An EMC plan for preventing disturbances is drawn up for the installation. A template is available from the local ABB representative. 3. The motor and control cables are selected as specified in this manual. 4. The drive is installed according to the instructions given in this manual. WARNING! To prevent radio-frequency interference, do not use a category C4 drive on a low-voltage public network which supplies domestic premises.

After disconnecting the input power, always wait for 5 minutes to let the intermediate circuit capacitors discharge before you start working on the drive, motor or motor cable. • The drive is to be used in a heated, indoor controlled environment. The drive must be installed in clean air according to the enclosure classification. Cooling air must be clean, free from corrosive materials and electrically conductive dust. • The maximum ambient air temperature is 50°C (122 °F) at rated current. Except for the R0 frame size, the current is derated for 50 to 60 °C (122 to 140 °F). • The drive is suitable for use in a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 480 V (or 240 V) maximum when protected by the UL fuses given in the table on page 85. The ampere rating is based on tests done according to the appropriate UL standard. • The cables located within the motor circuit must be rated for at least 75 °C (167 °F) in UL-compliant installations. • Integral solid state short circuit protection does not provide branch circuit protection. The input cable must be protected with fuses. Suitable IEC fuses are listed on page 84 and UL classified fuses on page 85. These fuses provide branch circuit protection in accordance with the National Electrical Code (NEC) and Canadian Electrical Code. For installation in the United States, also obey any other applicable local codes. For installation in Canada, also obey any applicable provincial codes. Note: Circuit breakers must not be used |
