Usage and Maintenance

Mount vertically; ≥80 mm clearance top/bottom for airflow

Separate power/signal cables; use shielded encoder cables (single‑end ground)

Clean fan/filters every 3–6 months in dusty environments

Check terminal tightness and cooling paths regularly

Load FWA firmware and set parameters via IndraWorks/DriveTop

Avoid frequent power cycling; disconnect power for long‑term shutdowns
