  • Page 6 CHAPTER 1: RECEIVING AND INSPECTION CHAPTER 1 RECEIVING AND INSPECTION This L2500 AC drive has gone through rigorous quality control tests at the factory before shipment. After receiving the AC motor drive, please check for the following: Receiving Check to make sure that the package includes an AC drive, the User Manual, and rubber bushings.
  • Page 7 CHAPTER 2 STORAGE AND INSTALLATION 2.1 Storage The AC drive should be kept in the shipping carton before installation. In order to retain the warranty coverage, the AC drive should be stored properly when it is not to be used over for an extended period of time.
  • Page 8 Mount the AC drive vertically and do not restrict the air flow to the heat sink fins. Non-Ventilated Enclosures When selecting non-ventilated enclosures for the L2500 series, please consider the following minimum distance (L) from the drive sides (other than the front or back covers) to the enclosure internal surfaces or box internal volume.
  • Page 9 Wait ten minutes for DC bus capacitors discharge. Any Electrical or mechanical modification to this equipment without prior written consent of WATT Drive GmbH. will void all warranties and may result in a safety hazard in addition to voiding the CE or UL listing.
  • Page 11 Failure to observe this precaution could result in bodily injury. When using L2500 series inverters in EU countries, the EMC directive 89/336/EEC must be observed. To satisfy the EMC directive and to comply with the standard, the following provisions should be obeyed:´...
  • Page 12 CHAPTER 3 WIRING Observe the following provisions for an electromagnetically compatible setup of your drive system: 1. As user you must ensure that the HF impedance between frequency inverter, filter and ground is as small as possible. • Take care it that the connections are metallic and have the largest possible areas (zink-plated mounting plates) 2.
  • Page 13 6. Safety measures • Ensure that the protective conductor terminal (PE) of the filter is properly connected with the protective conductor terminal of the frequency inverter. An HF ground connection via metal contact between the housings of the filter and the frequency inverter, or solely via cable shield, is not permitted as protective conductor connection.
