ebm-papst W3G800-KU21-D1 Operating Instructions Manual

Operating instructionsW3G800-KU21-D1Translation of the original operating instructions4.8 Checking connections; Ensure isolation from supply (all phases).; Make sure a restart is impossible; Check the cables for proper fit.; Screw the terminal box cover back on again. Terminal box tighteningtorque, see Chapter 3.1 Product drawing.; Route the cables in the terminal box so that the terminal box covercloses without resistance.; Use all screw plugs. Insert the screws by hand to avoid damage tothe threads.; Make sure the terminal box is completely closed and sealed and thatall screws and cable glands have been properly tightened.4.9 Switching on the deviceThe device may only be switched on if it has been installed properly andin accordance with its intended use, including the required safetymechanisms and professional electrical hookup. This also applies fordevices which have already been equipped with plugs and terminals orsimilar connectors by the customer.WARNINGHot motor housingRisk of fire→ Ensure that no combustible or flammable materials arelocated close to the fan.; Before switching on, check the device for visible external damageand make sure the protective devices are functional.; Check the fan's air flow paths for foreign matter and remove anyforeign matter found.; Apply the nominal supply voltage.; Start the device by changing the input signal.NOTEDamage to the device from vibrationBearing damage, shorter service life→ Low-vibration operation of the fan must be ensured over theentire speed control range.→ Severe vibration can arise for instance from inexperthandling, transportation damage and resultant imbalance orbe caused by component or structural resonance.→ Speed ranges with excessively high vibration levels andpossibly resonant frequencies must be determined in thecourse of fan commissioning.→ Either run through the resonant range as quickly aspossible with speed control or find another remedy.→ Operation with excessively high vibration levels canlead to premature failure.4.10 Switching off the deviceSwitching off the device during operation:; Switch off the device via the control input.; Do not switch the motor (e.g. in cyclic operation) on and off via powersupply.Switching off the device for maintenance:; Switch off the device via the control input.; Do not switch the motor (e.g. in cyclic operation) on and off via powersupply.; Disconnect the device from the power supply.; When disconnecting, be sure to disconnect the ground connection last.5. INTEGRATED PROTECTIVE FEATURESThe integrated protective functions cause the motor to switch offautomatically in the event of the faults described in the table.Fault Safety feature description/functionRotor position detection error An automatic restart follows.Blocked rotor ; After the blockage isremoved, the motor restartsautomatically.Line undervoltage (line voltageoutside of permitted nominalvoltage range); If the line voltage returns topermitted values, the motorrestarts automatically.Phase failure A phase of the supply voltagefails for at least 5 s.; When all phases are correctlysupplied again, the motorautomatically restarts after 10-40s.6. MAINTENANCE, MALFUNCTIONS, POSSIBLECAUSES AND REMEDIESDo not perform any repairs on your device. Send the device to ebm-papst for repair or replacement.WARNINGLive terminals and connections even with deviceswitched offElectric shock→ Wait five minutes after disconnecting the voltage at all polesbefore opening the device.CAUTIONIf control voltage or a stored speed set value is applied,the motor will restart automatically, e.g. after a powerfailure.Risk of injury→ Keep out of the device’s danger zone.→ When working on the device, switch off the line voltageand ensure that it cannot be switched back on.→ Wait until the device comes to a stop.→ After working on the device, remove any tools or otherobjects from the device.NOTEIf the device is not operated for a lengthy period in installedcondition in a dry environment, it is to be started up andoperated at full speed for one hour at least every four months. Ifthe device is not operated for a lengthy period in installedcondition in a damp environment (e.g. outdoors), it is to bestarted up and operated at full speed for at least three hoursonce a month to move the bearings and allow any condensatethat may have ingressed to evaporate.Malfunction/fault Possible cause Possible remedyItem no. 56589-5-9970 · ENU · Change 209539 · Approved 2021-02-01 · Page 13 / 16ebm-papst Mulfingen GmbH & Co.
