  • only allowed to be used for electrical specialist for the used electrical voltage and power conditions
  • only allowed to be used under electrical laboratory conditions
  • only allowed to be used in horizontal position on a non-conducting and non-inflammable surface
  • only allowed to be used with a wiring, which fulfills the current rating for the maximum possible currents.
  • only allowed to be used with a suitable current limiting circuit
    • The maximum continuous current must not exceed 30A.
    • The delivered fuse "Littelfuse Tpye 142.5631.5302" must be used as current limiter between connector J5 and J6.
    • To limit the current for smaller motor loads an ADDITIONALLY appropriate current limiter can be used e.g. a current limited power source or a fuse integrated in the wiring.
  • only allowed to be used with appropriate connectors at the M5 screw connectors, which means M5 cable lugs must be used and fastened according to technical standards.
  • only allowed to be used, if the "Drive Boad high current signals" conducting up to 30A nominal, are covered by isolating, mechanically stable, non-inflammable (UL V-1 or better) material
    • The "Drive Board high current signals" are the motor outputs A, B, C and Fuse F1 Connectors J5 an J6 and further internal connections shown white marked in the following picture:

    • As minimum protection it is mandatory to use the delivered "Isolating cover PCB" (marked in green), which must be mounted to the mounting holes H1, H9, H3, H4 with the delivered 10mm isolating spacers:

    • The used cable lugs need to be isolated in the area outstanding the outer border of the Drive Board
      Make sure that the "Isolating Cover PCB" is overlapping the conducting material by a minimum of 20 mm.
