- Converter operation: Requires Motion-Connect or shielded connection cables with high electrical conductivity. Shielding must be connected at both ends.
Usage Features
Safety Information: The document emphasizes safety, including warnings about rotating or live parts, thermal hazards (surfaces exceeding 100°C), electromagnetic fields (potential interference with pacemakers), and electrostatic sensitive devices (ESD). Qualified personnel are required for installation, commissioning, and maintenance. Five safety rules are outlined: disconnect the system, protect against reconnection, ensure equipment is de-energized, ground and short-circuit, and cover or enclose adjacent components.
Preparations for Use:
- Shipment and packaging: Upon receipt, check for completeness and transport damage. Report any issues immediately. Safety instructions are part of the supply. The rating plate is supplied separately and should be located near the motor.
- Transport and storage: Use suitable load-bearing equipment for transport. Lifting eyebolts are provided. Motors should be stored in a dry, dust-free room with relative humidity less than 60% and temperature not dropping below -15 °C. Protection against humidity and condensation is crucial.
- Installation: Motors must be installed on a flat, vibration-free base. Ensure proper alignment and secure fixing. Output elements must be attached correctly, observing shock-hazard protection measures. Feather keys must be secured if no output element is fitted.
Commissioning:
- Measures prior to commissioning: Verify electrical connection (correct rotation, insulation resistance, grounding, brake operation, speed limit), and proper functioning of monitoring equipment and cooling systems.
- Performing a trial run: Observe for hot steam during water cooling, ensure proper ventilation, and check for danger from rotating parts.
- Checking insulation resistance: Measure winding resistances and insulation resistances.
- Switching on the motor: Ensure frequency converter parameters are correctly assigned. Monitor for abnormal noises or vibrations. Observe maximum rotational speed.
- Cooling: Ensure cooling water supply is connected and temperatures are monitored. For forced ventilation, the fan must always be switched on.
Operation:
- Safety instructions: Do not remove covers when the motor is running. Immediately report any deviations from normal operation (e.g., increased power consumption, unusual noises). Be aware of hot surfaces.
- Stoppages: For extended periods of time, run the motor at regular intervals. For long shutdown periods, switch off the cooling water supply.

Spare Parts: A diagram and list of spare parts are provided, categorized by component (e.g., DE bearing assembly, rotor, stator, NDE bearing assembly, fan module, terminal box, encoder). Spare parts are available from Siemens Service Centers by specifying the motor designation.
Decommissioning and Disposal:
- Decommissioning: Components should be sorted for recycling (electronics waste, iron, aluminum, non-ferrous metal, insulating materials). Process materials and chemicals (oil, grease, solvents, paint residues) must be disposed of according to local regulations.
- Disposal: Environmentally friendly disposal is a priority. Contact a certified waste disposal organization. Follow safety rules, disconnect electrical connections, remove liquids and cables, detach fixings, and transport to a suitable location for disassembly.
- Dismantling the motor: Heavy parts must be secured to prevent falling. Motors can be recycled or returned to the manufacturer. Encoder electronics must be disposed of as electronic waste.
- Disposing of permanent magnets: Must be demagnetized prior to disposal, either by thermal treatment from a specialist company or by returning the machine to the manufacturer. Rotors with undemagnetized permanent magnets must not be transported.
- Disposing of components: Metals (steel, copper, aluminum) are recyclable. Winding insulation is incinerated during copper recycling. Insulating materials, cables, wires, and electronic waste should be sorted.
- Disposing of insulating liquid: Used MIDEL 7131® or similar insulating liquids must be incinerated or disposed of by a waste disposal company.
