| Engineering Category | Detailed Mechanical & Electrical Requirements |
|---|---|
| Mounting & Positioning | Install the AC drive strictly in a vertical orientation inside a dust-free control cabinet. Ensure the mounting plane is flat and rigid to shield the electronics from mechanical vibrations and sudden physical shock waves. |
| Thermal Clearance | Because this unit utilizes natural cooling convection, maintain an open, unobstructed safety clearance perimeter around the chassis. Allow sufficient airflow so that internal cabinet temperatures remain well below environmental thresholds. |
| Power Wiring Sizing | Dimension all electrical input mains and output motor cables based on load configurations. Ensure copper wire cross-sections comply with continuous input ratings (Heavy Duty: 19.3 A / Normal Duty: 21.8 A) and local NEC electrical code mandates. |
| Grounding & Noise Safety | Establish a direct, low-impedance ground circuit connection between the drive chassis terminal and the main power panel PE ground bus. Correct bonding is essential to suppress electromagnetic noise and eliminate leakage hazards. |
| Environmental Factors | Do not install the electronics assembly in processing areas exposed to high concentrations of conductive carbon dust, fine moisture aerosols, or aggressive chemical compounds that trigger circuit trace failures. |
