Installation Guidelines
Proper installation ensures the longevity and safety of the drive system. Follow these critical steps:
- Mount the unit vertically on a flat, non-combustible surface to ensure adequate convective heat dissipation.
- Maintain minimum clearances around the drive unit to prevent restriction of the cooling fan airflow.
- Use shielded motor cables to minimize electromagnetic interference (EMI) and cross-talk.
- Ensure proper grounding using a dedicated ground terminal.
- Verify that ambient conditions stay within the specified temperature (-20 degC to 60 degC storage) and non-condensing humidity parameters.
