Installation Guidelines

Cabinet Mounting: Ensure adequate spacing above and below the unit to allow for heat dissipation. Mount vertically on a flat surface.
Grounding: Proper grounding of the motor and drive is critical for EMC compliance. Connect the shield of the motor cable to the protective earth terminal.
Shielding: Use shielded motor cables to minimize RFI emissions. Ensure the shield is 360-degree clamped at the entry point of the enclosure.
Wiring: Keep control signal wiring separated from power and motor cabling to avoid signal cross-talk.
Parameterization: Use the relevant Siemens software tools or the Intelligent Operator Panel (IOP) to configure the drive parameters before commissioning.
