Transport and storage conditions

CONNECTION AND START-UP

Connecting the mechanical system

CAUTION
Cutting and crushing hazard when removing the fan from the packaging

• Carefully remove the device from its packaging, holding it by the centre of the blades only. Make sure to avoid any shock.
• Wear safety shoes and cut-resistant safety gloves.

NOTE

• Damage to device from vibration Bearing damage, reduced service life
• Forces or impermissibly high vibration levels must not be transmitted to the fan from system components.
• If the fan is connected to air ducts, it should isolated from vibrations, for example using compensators or similar elements.
• Fasten the fan to the substructure without distorting it.
• Check the device for transport damage. Damaged devices must no longer be installed.
• Install the undamaged device according to your application.

CAUTION

• Possibility of damage to the device
• Serious damage may result if the device slips during assembly.
• Keep the device fixed in position at the installation location until all attachment screws have been tightened.
• The fan must not be strained on fastening.

Connecting the electrical system

DANGER

• Electric voltage on the device Electric shock
• Always install a protective earth first.
• Check the protective earth.

DANGER Incorrect insulation

• Risk of fatal injury from electric shock
• Use only cables that meet the specified installation requirements for voltage, current, insulation material, load etc.
• Route cables such that they cannot be touched by any rotating parts.

CAUTION Electrical voltage

• The fan is a built-in component and features no electrically isolating switch.
• Only connect the fan to circuits that can be switched off with an all-pole separating switch.
• When working on the fan, you must switch off the installation/machine in which the fan is installed and secure it from being switched on again.

NOTE

• Water penetration into leads or wires
• Water enters at the cable end on the customers side and can damage the device.
• Make sure that the cable end is connected in a dry environment.
• Connect the device only to circuits that can be switched off using an all-pole disconnecting switch.

Prerequisites

• Check that the data on the type plate match the connection data.
• Before connecting the device, ensure that the supply voltage matches the operating voltage of the device.
• Only use cables designed for current according to the type plate.
• For determining the cross-section, follow the basic principles in accordance with EN 61800-5-1. The protective earth must have a cross-section equal to or greater than the outer conductor cross-section.
• We recommend the use of 105°C cables. Ensure that the minimum cable cross-section is at least AWG26/0.13 mm².

Protective earth contact resistance as per EN 60335

• Compliance with the resistance specifications as per EN 60335 for the protective earth connection circuit must be verified in the application. Depending on the installation situation, it may be necessary to connect an additional protective earth conductor by way of the extra protective earth terminal provided on the device.

Voltage control

NOTE

• Excessive current may occur with speed control using transformers or electronic voltage regulators (e.g. phase angle control). In addition, depending on how the unit is installed, noise and vibration can occur with phase angle control. Vibrations can lead to bearing damage, which can lead to premature failure.
• Heating-up of the motor when using voltage control must be checked by the customer following installation in the end device.

Frequency inverter

• Please use a frequency converter only after consultation with ebm-papst.
• For operation with frequency converters, fit sinusoidal filters that work on all poles (phase-phase and phase-earth) between the frequency converter and the motor.
• During operation with frequency converters, an all-pole sine filter protects the motor against high-voltage transients that can destroy the winding insulation system, and against harmful bearing currents.
• Heating-up of the motor when using a frequency converter must be checked by the customer following installation in the end device.

Connection of the cables

• External leads are brought out of device.
• First connect the “PE” (protective earth) connection.
• Connect the lines according to your application. When doing so, observe chapter 4.4 Connection screen.

Connection screen

Checking the connections

• Make sure that the power is off (all phases).
• Secure it from being switched on again.
• Check the correct fit of the connection lines.

Switch on device

• The device is not to be switched on until it has been installed properly and in accordance with its intended use, including the required protective devices and professional electrical connection. This also applies to devices which have already been equipped with plugs and terminals or similar connectors by the customer.

WARNING

• Hot motor housing Fire hazard
• Ensure that no combustible or flammable materials are located close to the fan.
• Inspect the device for visible external damage and the proper function of the protective features before switching it on.
• Check the air flow paths of the fan for foreign objects and remove any that are found.
• Apply the nominal voltage to the voltage supply.

NOTE

• Damage to device by vibrations Bearing damage, reduced service life
• The fan must operate free of vibrations throughout its speed control range.
• Strong vibrations can result from improper handling, imbalance resulting from damage during transport, or component-induced or structural resonances.
• When putting the fan into service, determine the speed ranges with excessive vibration levels and also any resonance frequencies that may be present.
• When regulating the speed, pass through resonance ranges as quickly as possible or find another remedy.
• Operation at excessive vibration levels can lead to premature failure.

Switching off the device

• Disconnect the device from the supply voltage at the main switch for the supply line.
• When disconnecting, be sure to disconnect the earth wire connection last.

MAINTENANCE, MALFUNCTIONS, POSSIBLE CAUSES AND REMEDIES

• Do not perform any repairs on your device. Return the device to ebm-papst for repair or replacement.

WARNING

• Terminals and connections have voltage even with a unit that is shut off Electric shock
• Wait five minutes after disconnecting the voltage at all poles before opening the device.

CAUTION

• The motor restarts automatically when operating voltage is applied, e.g. after a power failure.

Danger of injury

• Keep out of the danger zone of the device.
• When working on the device, switch off the mains supply voltage and secure the latter from being switched on again.
• Wait until the device stops.
• If the device remains out of use for some time, e.g. when in storage, we recommend switching the device on for at least two hours to allow any condensate to evaporate and to move the bearings.

Cleaning

• To ensure a long service life, the fans have to be regularly checked for proper operation and degree of soiling. The frequency of the checks is to be adapted to the occurrence of soiling.

DANGER

• Risk of injury from rotating fan.
• Only clean when not in motion. Interrupt the power supply, secure against renewed switch-on. Secure against start-up, prevent air flow.
• Dirt deposits on the motor housing could lead to overheating of the motor.
• Dirt on the impeller can cause vibration which would shorten the service life of the fan.
• Severe vibration could destroy the fan.
• In such cases immediately switch off and clean the fan.
• The preferred method of cleaning is dry cleaning, e.g. using compressed air.
• Use is never to be made of corrosive cleaning agents!
• NOTE Damage to the device during cleaning Malfunction possible
• Do not clean the device using a water jet or high-pressure cleaner.
• Do not use any acid, alkali or solvent-basedcleaning agents.
• Do not use any pointed or sharp-edged objects for cleaning
• Completely remove any cleaning agents used.
• Immediately switch off and replace the device if severe corrosion is apparent at load-bearing or rotating parts.
• Repairs to load-bearing or rotating parts are not permissible!
• Operate the fan for 2 hours at maximum speed to permit the evaporation of any water which may have ingressed.
• If cleaning does not eliminate vibration, the fan may have to be re- balanced. In such cases please contact ebm-papst.
• The fan is provided with maintenance-free ball bearings. The lifetime lubrication of the ball bearings is designed for a service life of 40,000 hours.
• Please contact ebm-papst if bearing replacement is required after this period.
• Adapt the maintenance intervals to the dust pollution occurring.
