Technical Specifications

Installation Guidelines

• Mounting: Mount the soft starter in a vertical position on a flat, non-flammable surface. Ensure the enclosure provides sufficient space for heat dissipation according to the manufacturer's thermal specifications.
• Wiring: Ensure motor and power cables are sized correctly for a 590 A current load to prevent overheating and voltage drop.
• Ventilation: Maintain adequate clearance around the unit to ensure proper air circulation; external cooling fans may be necessary in high-temperature environments.
• Grounding: Securely connect the chassis to a verified earth ground point to ensure safety and maintain immunity from electrical noise.
• Configuration: Follow the technical documentation to set the ramp-up and ramp-down times specific to the motor load characteristics.
