    Study Notes

    Suitability of Packaging

    • Stacking limitations: Only stack up to 2 equally sized crates to prevent property damage.
    • Packaging must comply with local transportation laws and regulations.
    • Crates provide stable protection for packaged goods during transport, ensuring no contact with ground or loading surfaces.
    • Packaged goods are stabilized within crates to avoid movement during transit.
    • Sealed plastic foil surrounds goods, alongside a desiccant to protect against humidity.

    Markings and Symbols

    • Packaging includes safety transport and storage instructions.
    • Mandatory symbols for non-hazardous goods protection include:
      • Protect against moisture
      • Handle with care (Fragile)
      • Attach lifting gear in designated areas
      • Indicate the Center of Mass for balanced handling

    Transportation and Handling Precautions

    • Closed transport crates must always be used; never open during transit.
    • Installation of mounting materials in transport crates is crucial for safety.
    • Only certified personnel should select and secure sling gear.
    • Avoid walking under hanging loads to prevent accidents.

    Assembly Process for Motor-Drive Unit

    • Secure assembly plates to brackets below the on-load tap-changer using a tightening torque of 60 ft·lb (80 Nm).
    • Align the motor-drive unit and insert shims for optimum drive shaft positioning.
    • Drive shaft connects the motor-drive unit and the on-load tap-changer through coupling brackets and bolts.
    • Pre-assembly greasing of coupling components recommended to facilitate connection.

    Drive Shaft Assembly

    • Keep the drive shaft ends aligned throughout the assembly process, maintaining vertical position within 2° deviation.
    • Dimension A between shaft ends must be determined and the square shaft cut accordingly, minus 0.35".
    • Coupling bolts are to be secured with a torque of 7 ft·lb (9 Nm), creating a 0.12" (3 mm) axial clearance.

    Electrical Connections

    • Establish grounding connections between the motor-drive unit housing and the transformer tank.
    • Follow strict electrical safety protocols: switch off, lock, ground, and cover energized parts before connections.
    • Confirm connections align with supplied connection diagrams and voltage specifications.

    Post-Assembly Checks

    • Tighten access door nuts on the on-load tap-changer to a maximum torque of 11 ft·lb (15 Nm).

    Drying Procedures

    • Avoid autoclave drying of the drive and on-load tap-changer to prevent damage.
    • If transformer drying in an autoclave, the drive should be removed before the process.

    Commissioning Procedures

    • Ensure only trained technicians work near the transformer to mitigate risks of explosive gases and injuries.
    • Use appropriate personal protective equipment and ensure the area is free from ignition sources.
    • Confirm that the oil compartment for the on-load tap-changer is filled per instructions, and all safety equipment is operational.

    Operator's Duty of Care

    • Operators must prevent accidents, disruptions, and environmental harm by adhering to safety protocols.
    • Compliance with all warning and hazard notices is mandatory.
    • Regular training on operational safety, operating instructions, and safety guidelines must be provided to personnel.
    • Safety regulations and procedures for accidents and fires should be readily accessible and visible in the workplace.
    • Equipment must be maintained in sound operational condition, with regular checks on safety equipment.
    • Only authorized replacement parts, lubricants, and auxiliary materials should be utilized for repairs or maintenance.
    • Operating conditions and installation site requirements specified by the manufacturer must be strictly followed.
    • Essential devices and personal protective equipment must be available for all applicable activities.
    • Maintenance intervals and regulations should be diligently adhered to.
    • Installation and commissioning must only be performed by qualified personnel in accordance with technical documentation.

    Personal Protective Equipment (PPE)

    • PPE must be worn during work to minimize health risks.
    • Personnel must always use the required PPE specific to their tasks.
    • Information about PPE should be clearly displayed in the work area.

    Warning Notices

    • Warning pictograms are essential for communicating hazards:
      • General danger point
      • Danger from electrical voltage
      • Warning regarding combustible substances
      • Risk of tipping

    General Safety Considerations

    • Thorough reading of the technical file is crucial to ensure safe installation, commissioning, and monitoring.
    • Proper use according to guidelines mitigates hazards throughout the product lifecycle.
    • High-quality assurance systems are in place to uphold health and safety standards.

    Inappropriate Use

    • Using the product against described guidelines is considered inappropriate and voids manufacturer liability.
    • Unauthorized modifications can lead to personal injuries and damage.

    Personnel Qualification

    • Only trained staff familiar with the product's operation should be involved in handling and monitoring.
    • Monitoring systems are designed to detect failures, especially during specific operational protocols.

    Monitoring System Actions

    • In case of malfunction, the monitoring system triggers procedures to stop operation and display error signals.
    • Visual alerts include yellow LEDs for signal errors and red LEDs for vacuum interrupter errors.

    Storage and Protection Measures

    • Stored products must be protected from moisture, dirt, pests, and unauthorized access.
    • Store on elevated structures to prevent moisture damage and facilitate ventilation.
    • Regular inspections of stored items are essential to ensure condition and integrity.

    Installation and Handling After Delivery

    • Products not installed within six months post-delivery require immediate corrective measures.
    • Regenerate drying agents and restore packaging integrity prior to installation.
    • Package handling must be careful to prevent damage and ensure safety during unpacking.
