• Protective measures must be taken against falling parts when mounting with ahanging rotor.• The custom designs must suit the prevailing conditions.• Tighten the fastenings with the specified torques.• Do not allow drilling chips, screws and other foreign bodies to reach the deviceinterior!• Any use below -10 °C is dependent on not being subjected to unusual, sudden ormechanical loads or stresses on the material (min. ambient temperature Technicaldata).• Corrosion is possible at the cutting edges on sendzimir galvanised parts.• Before the first switch-on, remove any items that may be present (borings, screws andother foreign objects) from the intake area - risk of injury from any objects that may flyout!4.2 Connection lead & terminal boxInformationIn demanding environments (wet areas, open air installation) all connections mustincorporate water drainage curves. To ensure that water cannot penetrate through to thecontroller housing from the connections install a terminal box lower than the motor.4.3 Mounting of centrifugal fans4.3.1 Mounting of centrifugal fans, RH designFor attachment to fixed motor flange use screws with property class 8.8 to EN ISO 4014and provide with suitable screw locking.Permissible tightening torques MAThread size M6(Special application with 5-pitch) M8Property class 8.8, friction coefcientμges = 0.129.5 Nm 23 NmScrew penetration ≥ 1.5 x d ≥ 1.5 x dWhen using screws with different friction values or strength classes, different tighteningtorques may be necessary.Information• Pay attention to a sufficient screw-in length in the motor flange.• Excess screw length not permissible and it may result in the rotor being brushedagainst or blocked.• Every screwing case is different. The tightening torque adapted to it must bedetermined by the appropriate screw tests.• In the case of a vertical motor axis, the respective lower condensation drain hole mustbe open.Assembly instructions ECblue MODBUS MountingL-BAL-F041-GB 1820 Index 003 Part.-No. 00296941-GB12/36
