    Introduction The purpose of this manual is to provide you with the basic information needed to install, start-up and troubleshoot the ILVFE Adjustable Frequency AC Drive. Who should use this manual? This manual is intended for qualified personnel. You must be able to program and operate Adjustable Frequency AC Drive devices.
  • Page 7: General Precautions

    General Precautions ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors have discharged before performing any work on the drive. Measure the DC bus voltage at the DC– and DC+ terminals on the Power Terminal Block (refer to Chapter 1 Power Terminal descriptions).

    ATTENTION: The following information is merely a guide for proper installation. Indulogix, cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this drive or associated equipment.
  • Page 10: Mounting The Unit

    Mounting the unit Mount the drive upright on a flat, vertical and level surface. Install on 35mm DIN-Rail (for frames A and B) or install with screws (see table 1.A below). Table 1.A Screw mounting recommendations Minimum Panel Thickness Screw Size Mounting Torque 1.9 mm (0.0747 inch.) M4 (#8-32)
  • Page 11: Ac Supply Source Considerations

    AC supply source considerations Ungrounded Distribution Systems ATTENTION: ILVFE drives contain protective MOVs that are referenced to ground. These devices must be disconnected if the drive is installed on an ungrounded or resistive grounded distribution system. Disconnecting MOVs To prevent drive damage, the MOVs connected to ground shall be disconnected if the drive is installed on an ungrounded distribution system where the line-to-ground voltages on any phase could exceed 125% of the nominal line-to-line voltage.
  • Page 12 Input Power Conditioning The drive is suitable for direct connection to input power within the rated voltage of the drive (see Appendix A). Listed in Table 1.C are certain input power conditions which may cause component damage or reduction in product life. If any of the conditions exist as described in Table 1.C, install one of the devices listed under the heading Corrective Action on the line side of the drive.
  • Page 13: General Grounding Requirements

    General grounding requirements The drive safety ground (PE) must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be periodically checked Figure 1.3 Typical grounding Safety Ground –...
  • Page 14: Fuses And Circuit Breakers

    RFI Filter Grounding Using single phase drives with integral filter, or an external filter with any drive rating, may result in relatively high ground leakage currents. Therefore, the filter must only be used in installations with grounded AC supply systems and be permanently installed and solidly grounded (bonded) to the building power distribution ground.
  • Page 15: Power Wiring

    Power wiring ATTENTION: National codes and standards and local codes outline provisions for safely installing electrical equipment. Installation must comply with specifications regarding wire types, conductor sizes, branch circuit protection and disconnect devices. Failure to do so may result in personal injury and/or equipment damage. ATTENTION: To avoid a possible shock hazard caused by induced voltages, unused wires in the conduit must be grounded at both ends.
  • Page 16 Reflected wave protection The drive should be installed as close to the motor as possible. Installations with long motor cables may require the addition of external devices to limit voltage reflections at the motor (reflected wave phenomena). See Table 1.E for recommendations. The reflected wave data applies to all frequencies 2 to 10 kHz.

  • Page 18: I/O Wiring Recommendations

    I/O wiring recommendations Important points to remember about I/O wiring: • Always use copper wire. • Wire with an insulation rating of 600V or greater is recommended. • Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot). Important: I/O terminals labeled “Common”...
