Operating instructionsR2E225-RA92-09Translation of the original operating instructions4. CONNECTION AND STARTUP4.1 Mechanical connectionCAUTIONCutting and crushing hazard when removing fan frompackaging→ Carefully remove the device from its packaging, by the fanimpeller. Strictly avoid shocks.→ Wear safety shoes and cut-resistant safety gloves.; Check the device for transport damage. Damaged devices are not tobe installed.; Install the undamaged device in accordance with your application.CAUTIONPossible damage to the deviceIf the device slips during installation, serious damage can result.→ Ensure that the device is securely positioned at its place ofinstallation until all fastening screws have been tightened.4.2 Electrical connectionDANGERVoltage on the deviceElectric shock→ Always connect a protective earth first.→ Check the protective earth.DANGERFaulty insulationRisk of fatal injury from electric shock→ Use only cables that meet the specified installationregulations for voltage, current, insulation material, capacity,etc.→ Route cables so that they cannot be touched by anyrotating parts.CAUTIONVoltageThe fan is a built-in component and has no disconnecting switch.→ Only connect the fan to circuits that can be switched off withan all-pole disconnection switch.→ When working on the fan, secure the system/machine inwhich the fan is installed so as to prevent it from beingswitched back on.NOTEWater ingress into wires or cablesWater ingress at the customer end of the cable can damage thedevice.→ Make sure the end of the cable is connected in a dryenvironment.Only connect the device to circuits that can be switched off withan all-pole disconnection switch.4.2.1 Requirements; Check whether the data on the nameplate match the connection dataand the data for the operating capacitor.; Before connecting the device, make sure the power supply matchesthe device voltage.; Only use cables designed for the current level indicated on thenameplate.For determining the cross-section, note the sizing criteria accordingto EN 61800-5-1. The protective earth must have a cross-sectionequal to or greater than that of the phase conductor.We recommend the use of 105 °C cables. Ensure that the minimumcable cross-section is at leastAWG 26 / 0.13 mm².Ground conductor contact resistance according to EN 60335Compliance with the impedance specifications according to EN 60335for the protective earth connection circuit must be verified in the endapplication.Depending on the circumstances of installation, it may be necessary toconnect an additional protective earth conductor to the extra protectiveearth terminal on the device.4.2.2 Voltage controlWith speed control using transformers or electronic voltageregulators (e.g. phase control), excessive current may occur.In addition, depending on how the device is installed, noisescan occur with phase control.4.2.3 Variable frequency drivePlease use a variable frequency drive only after consultation with ebm-papst.When a variable frequency drive is used for speed adjustment, themaximum safe operating speed (see 3.2 Nominal data) may not beexceeded.For operation with variable frequency drives, install sinusoidalfilters that work on all poles (phase-phase and phase-ground)between the drive and the motor.During operation with variable frequency drives, an all-polesine filter protects the motor against high-voltage transients thatcan destroy the coil insulation system, and against harmfulbearing currents.Heating of the motor due to use of a variable frequency drive must bechecked in the application by the customer.4.3 Connecting the cablesThe device has external leads.; First connect the "PE" (protective earth).● Connect the cables according to your application. When doing so,observe Chapter 4.4 Connection diagram.Item no. 10989-5-9970 · ENU · Change 89188 · Approved 2016-04-18 · Page 6 / 9ebm-papst Mulfingen GmbH & Co.
