Ensure that the air intake path is clear and that the facility's ambient temperature remains within the specified limits to prevent thermal derating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding for EMC:\u003c\/strong\u003e High-power PWM switching generates significant electromagnetic noise. Use a dedicated, low-impedance ground connection for the drive chassis. Use braided metallic shielding for all motor cabling and bond the shield 360 degrees to the motor terminal box and drive housing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance Schedule:\u003c\/strong\u003e Due to the high electrical stress at these power levels, perform an annual inspection of all power terminal screws to ensure they are torqued to manufacturer specifications.
