Consult with Mitsubishi if you are planning to use this product for special purposes, e.g. equipment or systems designed for manned transport vehicles, medical purposes, aerospace, nuclear power, electric power or undersea junctions.
  • Page 3 Please read here first (Continued) Safety Instructions This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the drive unit until you have read through this instruction manual and appended documents carefully and can use the equipment correctly.
  • Page 4 Please read here first (Continued) 1. Usage WARNING The MELIPM series motor is a synchronous motor with high-performance magnets built in its rotor. Therefore, after the drive unit is powered off, there are high voltages at the motor terminals while the motor is running. Before starting wiring or maintenance and inspection, make sure that the motor has stopped.
  • Page 5 Please read here first (Continued) 4. Wiring WARNING Any person who is involved in the wiring of this equipment should be fully competent to do the work. Otherwise, an electric shock or fire can occur. Install a no-fuse breaker or earth leakage circuit breaker. Otherwise, a drive unit failure can cause large currents to flow, resulting in a fire.
  • Page 6 Please read here first (Continued) 5. Operation WARNING Always replace the front cover before switching input power on. While power is on, do not remove the front cover. Doing so can cause an electric shock. Operate the switches with dry hands. Not doing so can cause an electric shock. Prepare an emergency stop switch separately.
  • Page 7 Please read here first (Continued) 6. Maintenance, Inspection and Part (Cooling Fan) Replacement WARNING Any person who is involved in maintenance, inspection or part replacement should be fully competent to do the work. Otherwise, an electric shock or injury can occur. Before starting maintenance, inspection or part replacement, make sure that the motor is at a stop, wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do the work.
