Page 6: Introduction
1 Introduction Introduction The 340 / 680/ 1220 DC Drive is a non-isolated speed controller for small brushed shunt wound or permanent magnet DC motors. This "non-isolated" drive has control signals that are NOT isolated from the mains supply, therefore, do not connect any of the terminals to earth or to other non-isolated equipment as when power is applied to the drive ALL terminals are at dangerous line potential. -

3.4 A (340 drive), 6.8 A (680 drive), 12.2 A (1220 drive) Min spd * Minimum For example, to adjust the preset on a 340 drive for a motor with an armature 0 to 30% o USER ADJUSTMENTS current rating of 1.7 A, set it to 50%. Use a suitable current meter temporarily connected in series with the armature to achieve accurate settings. - Page 8 The suggested Commissioning strategy starts in the safest possible mode of operation and progressively exercises each element of the system to achieve full functionality. WARNING! When power is applied to the drive, ALWAYS use an insulated tool when adjusting the presets. DIN rail release catch USER ADJUSTMENTS Supply jumper: (LV60 model will indicate 60/30 Vac)
