This document provides comprehensive operating instructions for a built-in device designed for air conveyance. It covers safety regulations, technical specifications, connection procedures, startup, integrated protective features, and maintenance guidelines.
The device is intended for use in stationary systems for conveying air within a specified ambient air pressure range (800 mbar to 1050 mbar) and within its permitted ambient temperature range. It is designed to operate with all protective devices in place and in accordance with the provided operating instructions. The device is suitable for power systems with grounded neutral (TN/TT), phase conductor grounding, or IT power systems, and in networks with quality characteristics as per EN 50160. All maintenance work should be performed as described in the manual.
Improper use, which is prohibited and potentially hazardous, includes operating the device in an unbalanced state (e.g., due to dirt or ice), in resonant operation with severe vibration (including vibration transmitted from the customer installation), or in medical equipment with life-sustaining or life-support functions. Conveying solids, abrasive particles, highly corrosive air (unless specifically designed for it), or air with high dust content (e.g., sawdust) is forbidden. Painting the device, allowing connections to loosen during operation, opening the terminal box during operation, or operating it near flammable materials or in an explosive atmosphere are also prohibited. The device must not be used as a safety component or for safety-related functions, nor should it be operated with protective devices that are completely or partially disassembled or manipulated.
The device features an integrated EMC filter for compliance with EMC limits, meaning reactive currents may be measured in the supply line even when the motor is at a standstill and the line voltage is switched on. The effective power in this operating state (operational readiness) is typically less than 5 W. For installations requiring a residual current device (RCD), only AC/DC-sensitive residual current devices (type B or B+) are permissible. Pulsed charging currents from the capacitors in the integrated EMC filter can cause instant tripping of RCDs, so residual current breakers with a trip threshold of 300 mA and delayed tripping (super-resistant, characteristic K) are recommended. The device also includes locked-rotor protection, ensuring the starting current (LRA) is equal to or less than the nominal current (FLA).
The device is equipped with various protective features that automatically switch off the motor in case of faults. These include rotor position detection error, blocked rotor, line undervoltage (line voltage outside of permitted nominal voltage range), and phase failure. In cases of rotor position detection error or blocked rotor, an automatic restart follows once the blockage is removed. If the line voltage returns to permitted values after an undervoltage event, the motor restarts automatically. In the event of a phase failure lasting at least 5 seconds, the motor will automatically restart after 10-40 seconds once all phases are correctly supplied again.
Maintenance features include regular checks for proper operation and soiling, with cleaning frequency adapted to the degree of soiling. The preferred cleaning method is dry cleaning, such as using compressed air. Aggressive cleaning agents, high-pressure cleaners, acids, alkalis, solvents, or pointed/sharp-edged objects should not be used. Any cleaning agents used must be completely removed. If severe corrosion is visible on load-bearing or rotating parts, the device must be switched off immediately and replaced, as repair of such parts is not permitted. After cleaning, the fan should be operated for 2 hours at maximum speed to evaporate any ingressed water. If cleaning does not eliminate vibrations, rebalancing may be necessary. The fan is equipped with maintenance-free ball bearings with a lifetime lubrication designed for a service life of 40,000 hours. If bearing replacement is needed after this period, ebm-papst should be contacted. Maintenance intervals should be adapted to the actual level of dust exposure.
A safety inspection involves checking the contact protection cover for intactness or damage, inspecting the device for damage to blades and housing, ensuring proper fastening of cables, checking cable insulation for damage, and inspecting the impeller for wear, deposits, corrosion, and damage. The tightness of cable glands and condensation drainage holes should also be visually inspected. Abnormal bearing noise requires acoustic inspection, and a vibration test is recommended to check for excessive vibration levels.
The device's electronics housing features an LED that indicates motor status with various colors and flash codes. Green signifies no warning or fault, orange indicates a warning (no user intervention required), and red indicates at least one error. Flash codes have a frequency of 2 Hz, followed by a 3-second pause. If multiple simultaneous errors occur, their associated flash codes are displayed in succession. If both warnings and errors are present, only the errors are displayed.
For long-term storage in a dry environment, the device should be started and operated at full speed for at least one hour every four months. In damp environments (e.g., outdoors), it should be started and operated at full speed for at least two hours once a month to move the bearings and allow any condensate to evaporate.
