• Always disconnect all power sources before working on the equipment.
• Ensure proper grounding of the equipment.
• Verify all wiring connections comply with local and national electrical codes.
• Do not operate the device if it appears damaged.
• Wear appropriate personal protective equipment (PPE).

3. Product Overview

The Schneider Electric Altistart 01 soft starter is a compact device designed for DIN rail mounting. It features intuitive controls and indicators for easy setup and monitoring.

Figure 1: Front view of the Schneider Electric ATS01N125FT Altistart 01 Soft Starter. The image displays the top power input terminals (1 L1, 3 L2, 5 L3), the Schneider Electric logo, a green "Power ON" LED, a yellow "Full Voltage" LED, and two rotary adjustment knobs labeled "Start Time" and "Initial Voltage". The bottom section shows green control terminals.

3.1. Components

• Power Input Terminals (1 L1, 3 L2, 5 L3): Located at the top, these terminals are for connecting the main power supply to the soft starter.
• Power ON LED (Green): Indicates when the device is powered.
• Full Voltage LED (Yellow): Illuminates when the motor has reached its nominal voltage.
• Start Time Adjustment Knob: Controls the duration over which the motor accelerates to full speed.
• Initial Voltage Adjustment Knob: Sets the starting voltage applied to the motor.
• Control Terminals: Located at the bottom, these are for control wiring (e.g., run command, fault indication).

4. Setup

4.1. Mounting

The ATS01N125FT is designed for DIN rail mounting. Ensure adequate ventilation space around the unit to prevent overheating.

1. Securely attach the soft starter to a standard DIN rail in a suitable enclosure.
2. Ensure the mounting is stable and free from excessive vibration.

4.2. Wiring

All wiring must be performed by qualified electricians in accordance with local and national electrical codes.

• Power Supply: Connect the main power supply (110V to 480V AC, single or 3-phase) to the L1, L2, L3 terminals at the top of the unit.
• Motor Connection: Connect the motor leads to the corresponding output terminals (T1, T2, T3) at the bottom of the unit (refer to the product's wiring diagram for specific terminal assignments, not explicitly visible in the provided image but standard for soft starters).
• Control Wiring: Connect control signals (e.g., start/stop, fault reset) to the low-voltage control terminals as per your application's requirements and the detailed wiring diagram provided with the product.

4.3. Initial Adjustments

The Altistart 01 features two simple adjustment knobs for configuration.

• Start Time: Adjust this knob to set the desired acceleration time for the motor. A longer start time provides a smoother ramp-up, reducing mechanical shock.
• Initial Voltage: Adjust this knob to set the initial voltage applied to the motor at startup. A lower initial voltage reduces starting current and torque.

Refer to your motor's specifications and application requirements to determine optimal settings. Start with conservative settings and adjust as needed.

5. Operating Instructions

5.1. Powering On

Once wired and configured, apply power to the soft starter.

• The green "Power ON" LED will illuminate, indicating the unit is receiving power.
• Initiate the motor start command via your control system. The soft starter will begin ramping up the motor voltage according to the "Start Time" and "Initial Voltage" settings.
• The yellow "Full Voltage" LED will illuminate once the motor has reached its nominal operating voltage and the soft starter has bypassed its internal power electronics.

5.2. Normal Operation

During normal operation, the green "Power ON" LED and the yellow "Full Voltage" LED should both be illuminated when the motor is running at full speed. The integrated bypass feature reduces heat dissipation and noise during full-speed operation.

5.3. Stopping the Motor

To stop the motor, remove the run command signal. The motor will coast to a stop. The yellow "Full Voltage" LED will extinguish, while the green "Power ON" LED will remain lit as long as the unit is powered.

6. Maintenance

The Altistart 01 soft starter is designed for minimal maintenance. Regular inspections are recommended to ensure optimal performance and longevity.

• Visual Inspection: Periodically check for any signs of physical damage, loose connections, or discoloration due to overheating.
• Cleaning: Ensure the unit is free from dust and debris. Use a soft, dry cloth for cleaning. Do not use solvents or abrasive cleaners.
• Ventilation: Verify that ventilation openings are not obstructed to allow for proper heat dissipation.
• Connection Tightness: Periodically check the tightness of all electrical connections.

Always disconnect power before performing any maintenance.
