Compliance with this standard isachieved through the use of an unscreened motor feed cable.5.3.2 Control cablesPay attention to sufficient distance from powerlines and motor wires to prevent interferences. Thecontrol cable may not be longer than 30 m. Screened control cables must be used when the cablelength is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.only to the control unit with the protective ground (keep cable short and with as little inductance aspossible!).5.3.3 Harmonics current for devices ≥ 4 and ≤ 16 AAccording to EN 61000-3-2 these devices are to be classified as “professional” devices.Connection to a low voltage supply (public networks) is allowed insofar as this has been clarified withthe respective energy supply company responsible.5.3.4 Harmonics current and line impedance for devices > 16 A and ≤ 75 AExtract from EN 61000-3-12, valid for equipments with rated current > 16 A and ≤ 75 A, connected topublic low-voltage systems.This equipment complies with IEC 61000-3-12 provided that the short-circuit power SSC is greater than or equalto RSCE x Sequ at the interface point between the user's supply and the public system.It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distributionnetwork operator if necessary, that the equipment is connected only to a supply with a short-circuit power SSCgreater than or equal to RSCE x Sequ.SSC Short-circuit power from line at the interface point between the user's supply and the public systemSequ Rated - apparent power for three phase devices: Sequ = √3 x UI x Iequ(UI = phase to phase voltage Technical data “Line voltage”)(Iequ = rated current of the device Technical data “Rated current input”)RSCE Short-circuit ratioFor this devices: RSCE ≥ 1205.4 Mains connection5.4.1 Line voltagePower from the mains is connected to terminals: PE, L1, L2, L3 and N (depending on type). Here, itmust be strictly observed that the mains voltage lies within the allowable tolerance specifications (Technical data and nameplate affixed to the side).The neutral conductor connection “N” is only available for the device types with 22 A rated current forthe reduction of the leakage current. It is irrelevant for the device’s functionality, for those supplynetworks without neutral conductors the connection is not required. Because however, higher leakagecurrents can flow through the “PE” conductor connection, undesirable erroneous activation may occuron systems equipped with FI circuit breakers.Attention!• Not suitable for IT system!• Do not operate on Grounded Delta System!• To activate the on current limitation, you must wait at least 90 seconds after switching off the linevoltage before switching back on!Operating Instructions Fcontrol – model series FXDM Electrical installationL-BAL-E072-GB 1642 Index 008 Part.-No.16/105
