Usage and Maintenance

Install the drive vertically and ensure adequate ventilation inside the cabinet.

Keep ambient temperature below 45 °C during operation.

Install the firmware module correctly and complete all wiring before commissioning. Configure parameters via IndraWorks software.

Clean internal fan and heat sink every 6 months, and inspect terminal connections periodically. Calibrate control loops every 2 years to maintain stable operation.

Transfer the firmware module to a new unit directly for rapid system recovery when drive replacement is needed.
