This document is an instruction manual for the high-performance compact inverter, providing information on the handling procedure for correct use and the potential issues that may arise from improper handling. It is recommended to deliver this manual to the end user and keep it in a safe place. For instructions on using optional devices, refer to their respective instruction and installation manuals.
This instruction manual covers the correct handling, installation, wiring, operation, and maintenance of the FRENIC-Multi series of inverters. The device is specifically designed to drive a three-phase induction motor for fan and pump applications. Improper handling may result in incorrect operation, a short life, or failure of the product and motor.
The manual provides detailed safety precautions regarding installation on nonflammable materials, proper wiring procedures including the use of circuit breakers and grounding, and operational guidelines such as terminal cover usage and keypad settings. It also outlines maintenance and inspection procedures, emphasizing that these tasks should only be performed by qualified persons after turning the power off and waiting for the DC link bus voltage to drop below 25 VDC.
The product is designed specifically to drive a three-phase induction motor for fan and pump applications.
You must turn the power OFF and wait at least five minutes, then verify that the DC link bus voltage between terminals P (+) and N (-) is lower than 25 VDC.
The filter circuit may overheat if the wiring length between the inverter and motor exceeds 10 m.
