Mount the drive vertically with a minimum clearance of 150 mm above and below the housing to facilitate effective natural convection. In enclosed cabinets, ensure that the ambient temperature is monitored and kept below the maximum rated limit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Shielding:\u003c\/strong\u003e To minimize electromagnetic interference (EMI), ensure the motor output cables are shielded and that the shield is terminated to the drive's PE (Protective Earth) terminal with a low-impedance connection. Keep signal cabling (I\/O) physically separated from power lines to prevent signal cross-talk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommissioning Protocol:\u003c\/strong\u003e Before engaging the run signal, verify that the drive’s parameters—specifically the motor nameplate data (voltage, frequency, and rated current)—are accurately programmed.
