Installation Guidelines

• Mounting: Mount the drive vertically in an upright position. Ensure the supporting structure can accommodate the unit's weight and dimensions.
• Cooling: Although IP55-rated, ensure sufficient clearance is maintained for thermal management to prevent internal overheating.
• Wiring: Use appropriately shielded cables to connect the motor. Ensure the brake chopper connection is wired to a suitably rated external braking resistor if required by the application dynamics.
• Grounding: A dedicated, low-impedance earth connection to the chassis is essential for safety and to minimize electromagnetic interference.
• Protection: Ensure that input power is protected by appropriate circuit breakers or fuses as per the manufacturer's technical documentation.
