  • Page 2: Safety Instructions

    Preface Thank you for purchasing our EQ5 series inverter. This product is used to drive a 3-phase electric motor at variable speed. As incorrect use of this product may result in personal injury and/or property damage, please read all safety and operating instructions before using. Safety Instructions Please read this manual carefully before installing, connecting (wiring), operating, servicing, or inspecting the inverter.
  • Page 3 • Turn off the power before starting the wiring, otherwise electric shock may result. • Wire the inverter after installation is complete, otherwise electric shock or injury may occur. • Confirm that the phases and rated voltage of this product match those of the AC power supply, otherwise injury may result.
  • Page 4 Instructions on maintenance, inspection, and replacement: • Wait a minimum of five minutes (30HP/CT, 40HP/VT or less) or ten minutes (40HP/CT, 50HP/VT or more) after power has been turned off (open) before starting an inspection. (Also confirm that the charge lamp is off and that DC voltage between terminals P (+) and N (-) does not exceed 25V.) Otherwise electrical shock may result.
  • Page 5 Connector must be fixed using the crimp tool specified by the connector manufacturer. * Connect the power supply to main power supply terminals via the Molded-case circuit breaker (MCCB) or a ground fault circuit interrupter (GFCI) to conform to the UL Listing Mark.

    10. Electromagnetic Compatibility (EMC) 10-1 General In accordance with the provisions described in the European Commission Guidelines Document on Council Directive 89/336/EEC, the EQ5 series of inverters is chosen to be classified as "Complex Components". Classification as a "Complex Components" allows a product to be treated as an "apparatus", and thus permits compliance with the essential requirements of the EMC Directive to be demonstrated to both an integrator of EQ5 Inverters and to his customer or the installer and the user.
