Fans with IEC standard motor
The document stresses the importance of following safety symbols and guidelines to prevent hazards such as electric shock, crushing, and falling loads. Although Rosenberg fans are manufactured to high standards, improper use can be dangerous.
This manual covers various types of radial and roof fans, including those with standard motors and different impeller designs.
Rosenberg radial fans are designed for modern ventilation systems, featuring standard motors and the ability to rotate in 90° increments. They are balanced both statically and dynamically.
Fans should be used within specified performance limits and are suitable for clean or slightly contaminated air, slightly aggressive gases, and mediums with specific temperature and humidity ranges. Compliance with DIN EN ISO standards is required.
Fans must operate at least in a "3-Stage + OFF" mode as per EU regulations. Different motor types offer various control options, and the operator is responsible for compliant operation.
The maximum speed of fans is determined by motor specifications, and care must be taken not to exceed these limits to avoid overloading.
Only authorized accessories should be used, and they must be maintained according to fan cleaning guidelines.
Fans should be stored in dry, weather-protected environments and transported using appropriate equipment to avoid damage.
Installation should be performed by trained personnel, ensuring sufficient space for maintenance. Electrical work must comply with relevant regulations.
1. Ensure protection against foreign objects entering the fan using guards certified to DIN EN ISO 13857.
2. Check the fan for transport damages before installation; do not install damaged fans.
3. In hazardous areas, connect all conductive parts to a voltage equalizing system.
4. Radial fans should not be distorted; ensure no warping or shifting that could cause knocking or grinding of moving parts.
5. Handle the fan only by its base frame or designated lifting points.
6. Roof fans require airtight sealing on mounting surfaces to prevent deformation and ensure free rotation of the impeller.
7. Fans are designed for horizontal installation or up to a 5° incline; use a special inclined roof socket for greater inclines.
1. Radial fans should operate with horizontal shafts; non-horizontal positions may reduce bearing life.
2. Use non-loosening screw connections for installation.
3. Electrical connections must comply with technical and local regulations.
4. Ensure proper grounding and equipotential bonding.
5. For roof fans, ensure the mains supply line is sealed properly and connected to the appropriate terminal box.
1. Remove foreign objects from the fan before checking the direction of rotation.
2. Install protection guards and check the impeller for smooth rotation.
3. Verify the direction of rotation using the direction arrow on the casing.
4. Adjust motor phases to change rotation direction if necessary.
1. The DVNF fan operates via a frequency converter; observe special connection conditions.
2. Ground wire connections must match the power supply cross-section.
3. Fans must operate in neutral point earthed networks with permissible asymmetry less than 2%.
4. Total Harmonic Distortion (THD) must be less than 10%.
5. Follow EN 60204-1 for low-voltage system connections.
6. Use specified fuses for cable protection, not device protection.
1. Motor protection switches are not allowed in the DVNF fan's mains supply circuit.
2. Earth leakage circuit breakers must handle leakage currents and be suitable for pulsating and smooth DC fault currents.
3. Ensure proper earth protection to avoid dangerous voltages on the unit's surface.
4. If leakage current exceeds 3.5 mA, connect a second earth protection cable.
1. Maintain a distance of more than 10 cm between main supply and control cables.
2. Control cable length should not exceed 30m; use shielded cables for lengths over 20m.
3. Insulation tests are only permitted for mains connections, not control terminals.
1. Insulation Test: Conducted using EN 60204-1 standards with a DC voltage of 500VDC. Ensure all connection cables are disconnected at the Controller to avoid high voltages.
2. Pin Connection: The motor PTC must be connected to contacts 11 and 12 for operation. Incorrect connections can damage electronics.
3. Power Supply: For 3-phase devices, mains terminals must be bridged. The power supply should be disconnected for at least two minutes before working on motor wiring.
1. Connection Terminals: Use core sleeves for multi-core cables. Terminals are spring-loaded for easy wire insertion. Stripped wire ends should be 8-15 mm long.
2. Junction Box Overview: Includes motor connection terminals, optional module connectors, and power terminals.
3. Initial Checks: Ensure installation is complete, safety devices are fitted, and no foreign particles are present. Verify connection data with the motor type plate.
4. Operation: Initiate by qualified personnel only. Check for correct rotation and operation.
1. Monitoring Functions: Includes under/over voltage, locked rotor, over temperature, current protection, and phase fault detection.
1. Common Issues: Includes missing power supply, poor electrical connections, and missing control signals. Ensure compliance with safety regulations during maintenance.
1. Alarm Relay: Switches from COM-NC to COM-NO if no fault is detected. Note relay status during startup.
2. LED Indications: Green light indicates no alarm, flashing green indicates active communication, flashing red indicates non-critical alarms, and constant red indicates critical alarms.
1. 0-10V Control Signal: Ensure the potentiometer's 0-10V control signal is correctly connected with a minimum internal resistance of 4 kΩ. Verify the alarm relay function.
2. Motor Protection: If the motor is stopped due to overload or alarm, reset by disconnecting the controller for 60 seconds. Check for blocked impeller and foreign objects.
3. Controller and Motor Issues: Replace defective controllers or motors. Ensure correct phase connections between controller and motor to avoid wrong rotation direction.
1. IEC Standard Motors: As per regulation 640/2009/EC, motors from 2015 must be IE3 or IE2 with a VSD for motors >=7.5kW, and from 2017 for motors >=0.75kW.
2. Maintenance: Conducted by qualified personnel. Fans are largely maintenance-free under normal conditions. Bearings designed for 20,000h lifespan, but should be replaced every 5 years due to grease aging.
1. Components: Consists of a circular lead with pressure measuring devices in the inlet cone.
2. Function: Measures air volume based on pressure difference between static pressures at the inlet cone and inlet area.
3. Calibration: Calibration factor k10 determined with at least 10% accuracy.
1. Disposal: Follow local regulations for disposal. Environmentally friendly design and safety considered in fan development.
2. Dismantling: Conducted by trained personnel. Prepare by contacting waste management, disconnecting power, and removing liquids.
1. Safety: Ensure fan impeller is stopped and electrical circuit is disconnected before maintenance.
2. Cleaning: Regular cleaning prevents distortions. Do not use high-pressure cleaners.
3. Inspection: Check for unusual noises, bearing clearance, and surface protection.
Ensure that machine parts are secured against falling before dismantling to prevent serious injury and property damage.
The machine is primarily composed of metallic materials, which are fully recyclable. Components should be separated into categories such as steel and iron, aluminum, non-ferrous metals, insulating materials, cables and wires, electrical scrap, and plastics. Materials and chemicals should be disposed of according to local regulations, including fats and paint residues. Packaging materials like wood, foam, and cartons should be managed according to regional requirements, with contaminated materials directed to thermal utilization.
Rosenberg products undergo continuous quality control and comply with current regulations. For inquiries, contact the air handling unit constructor, a Rosenberg branch, or directly at Rosenberg Ventilatoren GmbH.
Rosenberg declares that its products meet applicable EC/EU directives. The declaration of conformity is available on the Rosenberg website and is valid for independently operated fans with sinusoidal current supply. The ErP directive compliance is valid only with ErP-related data on the product information and nameplate. The declaration of incorporation applies to products mentioned in the manual and serves as an assembly instruction under the machinery directive Annex XI.
