NoteIn order to ensure sufficient cooling of the motor,the distance (D) between the end of the fan coverand a wall or other fixed objects must always beat least 50 mm, irrespective of motor size.See fig. 3.Carry out the electrical connection according to local regulations.Check that the supply voltage and frequency correspond to thevalues stated on the nameplate.WarningDo not make any connections in the terminal boxunless the power supply has been switched offfor at least 5 minutes.Make sure that the power supply cannot beaccidentally switched on.TM05 5236 3512The motor must be earthed and protected againstindirect contact in accordance with localregulations.DFig. 3Minimum distance (D) from the motor to a wall or otherfixed objectsIf the power supply cable is damaged, it must bereplaced by the manufacturer, the manufacturer’sservice partner or a similarly qualified person.Note6.1 Protection against electric shock, indirect contact5.5 Outdoor installationWhen installed outdoors, the motor must be provided with asuitable cover to avoid condensation on the electroniccomponents. See fig. 4.NoteThe user or the installer is responsible for theinstallation of correct earthing and protectionaccording to local regulations. All operationsmust be carried out by a qualified electrician.WarningWhen fitting a cover to the motor, observe theguideline in section 5.4 Ensuring motor cooling.The cover must be sufficiently large to ensure that the motor isnot exposed to direct sunlight, rain or snow. Grundfos does notsupply covers. We therefore recommend that you have a coverbuilt for the specific application. In areas with high air humidity,we recommend that you enable the built-in standstill heatingfunction. See section Standstill heating, page 27.The motor must be earthed and protected againstindirect contact in accordance with localregulations.Protective-earth conductors must always have a yellow/green(PE) or yellow/green/blue (PEN) colour marking.6.1.1 Protection against mains voltage transientsThe motor is protected against mains voltage transients inaccordance with EN 61800-3.6.1.2 Motor protectionTM05 3496 3512The motor requires no external motor protection.

6.4 Additional protection6.4.1 Single-phase motorsIf the motor is connected to an electric installation where an earthleakage circuit breaker (ELCB) or ground fault circuit interrupter(GFCI) is used as additional protection, this circuit breaker orinterrupter must be marked with the following symbol:ELCB(GFCI)NoteWhen an earth leakage circuit breaker or groundfault circuit interrupter is selected, the totalleakage current of all the electrical equipment inthe installation must be taken into account.The motor must be connected to a power supply with a qualitycorresponding to IEC 60146-1-1, class C, to ensure correct motoroperation at phase unbalance.This also ensures long life of the components.6.5 Functional modulesVarious functional modules are available for this product.The selection of module depends on the application and therequired number of inputs and outputs.Possible functional modules: Basic functional module (FM 100) Standard functional module (FM 200)The leakage current of the motor can be found in section15.2 Leakage current. Advanced functional module (FM 300).6.4.2 Motors supplied from a renewable-energy sourceThe descriptions and terminal overviews in this section apply toboth single- and three-phase motors.This section only applies to motor variants designed for supplyfrom a renewable-energy source (1 x 90-240 V - 10 %/ 10 %,50/60 Hz, PE or 30-300 VDC).Overvoltage and undervoltage protectionOvervoltage and undervoltage may occur in case of unstablepower supply or a faulty installation. The motor will be stopped ifthe voltage falls outside the permissible voltage range. The motorwill automatically be restarted when the voltage is again withinthe permissible voltage range. Therefore, no additional protectionrelay is required.NoteThe motor is protected against transients fromthe power supply according to EN 61800-3.In areas with high lightning intensity, werecommend external lightning protection.6.6 Connection terminals on functional modulesFor maximum tightening torques, see section Torques, page 33.6.6.1 Basic functional module (FM 100)The FM 100 has only the most necessary inputs for closed- andopen-loop operation. The module also enables communicationvia a GENIbus connection.The FM 100 has these connections: analog voltage input two digital inputs or one digital input and one open-collectoroutput GENIbus connection.See fig. 10.NoteDigital input 1 is factory-set to be start/stop inputwhere open circuit will result in stop. A jumperhas been factory-fitted between terminals 2 and6. Remove the jumper if digital input 1 is to beused as external start/stop or any other externalfunction.NoteAs a precaution, the wires to be connected to theconnection groups below must be separatedfrom each other by reinforced insulation in theirentire lengths.Overload protectionIf the upper load limit is exceeded, the motor will automaticallycompensate for this by reducing the speed and stop if theoverload condition persists.The motor will remain stopped for 8 seconds. After this period,the motor will automatically attempt to restart. The overloadprotection prevents damage to the motor. Consequently, noadditional motor protection is required.Overtemperature protectionThe electronic unit has a built-in temperature sensor as anadditional protection. When the temperature rises above a certainlevel, the motor will automatically compensate for this byreducing the speed and stop if the temperature keeps rising.The motor will remain stopped for 8 seconds. After this period,the motor will automatically attempt to restart. Inputs and outputThe inputs and output are internally separated from themains-conducting parts by reinforced insulation andgalvanically separated from other circuits.All control terminals are supplied by safety extra-low voltage(SELV), thus ensuring protection against electric shock.6.4.3 Three-phase motors If the motor is connected to an electric installation where an earthleakage circuit breaker (ELCB) or ground fault circuit interrupter(GFCI) is used as additional protection, this circuit breaker orinterrupter must be of the following type:A galvanically safe separation must fulfil the requirements forreinforced insulation including creepage distances andclearances specified in EN 61800-5-1. It must be suitable for handling leakage currents and cutting-inwith short pulse-shaped leakage. It must trips out when alternating fault currents and faultcurrents with DC content, i.e. pulsating DC and smooth DCfault currents, occur.Mains supply (terminals N, PE, L or L1, L2, L3, PE).For these motors an earth leakage circuit breaker or ground faultcircuit interrupter, type B, must be used.This circuit breaker or interrupter must be marked with thefollowing symbols:ELCB(GFCI)NoteWhen an earth leakage circuit breaker or groundfault circuit interrupter is selected, the totalleakage current of all the electrical equipment inthe installation must be taken into account.The leakage current of the motor can be found in section16.2 Leakage current.9English (GB)Protection against phase unbalance
