7 Introduction to the manual 7 Introduction to the manual What this chapter contains This chapter describes the manual. It contains section Precautions before electrical work. Target audience The manual is intended for people who check whether EMC filter options or groundto-phase varistors of the drive need to be disconnected before the drive is connected to different electrical power systems. It is intended for people who disconnect the filter or varistors. Applicability The manual contains instructions for frames R1 to R9 of ACS and ACS for frames R10 and R11 of ACS880-04, ACS880-04XT and ACS for frames R8 and R11 of ACS and ACS Safety Obey the instructions in the hardware manual. Precautions before electrical work These warnings are for all personnel who do work on the drive, motor cable or motor. WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrician, do not do electrical installation or maintenance work. Go through these steps before you begin any installation or maintenance work.

8 8 Introduction to the manual 1. Clearly identify the work location. 2. Disconnect all possible voltage sources. Open the main disconnector at the power supply of the drive. Make sure that reconnection is not possible. Lock the disconnector to open position and attach a warning notice to the disconnector. Disconnect any external power sources from the control circuits before you do work on the control cables. After you disconnect the drive, always wait for 5 minutes to let the intermediate circuit capacitors discharge before you continue. 3. Protect any other energized parts in the work location against contact. 4. Take special precautions when close to bare conductors. 5. Measure that the installation is de-energized. Use a multimeter with an impedance of at least 1 Mohm. Make sure that the voltage between the drive input power terminals (,, ) and the grounding terminal (PE) is close to 0 V. Make sure that the voltage between the drive DC terminals (UDC+ and UDC-) and the grounding terminal (PE) is close to 0 V. 6. Install temporary grounding as required by the local regulations. 7. Ask for a permit to work from the person in control of the electrical installation work. Related manuals See List of related manuals on the inside of the front cover.

10 10 Frames R1 to R9 Checking the compatibility with IT (ungrounded) and corner-grounded delta systems EMC filter EMC filters +E200 and +E202 are not suitable for use on an IT (ungrounded) system. The filters in frames R5 to R9 are also not suitable for use on cornergrounded and midpoint-grounded delta systems. See section Disconnection table (page 11). Disconnect the filter before you connect the drive to the supply network. WARNING! Do not install any drive frame size with EMC filter +E200 or +E202 on an IT system (an ungrounded power system or a high-resistance-grounded [over 30 ohms] power system), or frames R5 to R9 with EMC filter +E200 or +E202 on a corner-grounded or midpoint-grounded delta system. The system will be connected to ground potential through the EMC filter capacitors of the drive. This can cause danger, or damage the drive. Note: When the internal EMC filter is disconnected, the drive EMC compatibility is considerably reduced. Ground-to-phase varistor The ground-to-phase varistor of the drive is not suitable for use on an IT (ungrounded) system. Disconnect it before you connect the drive to the supply network. Check the table on page 11. WARNING! Do not install the drive with the ground-to-phase varistor connected on an IT system (an ungrounded power system or a highresistance-grounded [over 30 ohms] power system). The varistor circuit can be damaged. Corner-grounded and midpoint-grounded 690 V delta systems WARNING! Do not install the drive on a 690 V corner-grounded or midpointgrounded delta system. Disconnecting the EMC filter and ground-to-phase varistor does not prevent damage to the drive.

20 20 Frames R10 and R11 Checking the compatibility with IT (ungrounded) and corner-grounded delta systems EMC filter +E200 (690 V drives and drive modules) internal EMC filter +E200 is not suitable for use on an IT (ungrounded) system. See section Disconnection table (page 21). Disconnect the filter before you connect the drive to the supply network. WARNING! Do not install any drive with EMC filter +E200 on an IT system (an ungrounded power system or a high-resistance-grounded [over 30 ohms] power system). The system will be connected to ground potential through the EMC filter capacitors of the drive. This can cause danger, or damage the drive. Note: When the internal EMC filter is disconnected, the drive EMC compatibility is considerably reduced. EMC filter +E202 and ARFI-10 (ordering code ) 400 V and 500 V drives and drive modules) EMC filter +E202 (ARFI-10 also available with ordering code for ACS880-04XT) is not suitable for use on an IT (ungrounded) system.
