Connecting the AC Cable

Qualified person

Requirements:

  • A suitable medium-voltage transformer must be available. For the SHP 100-21, depending on the local standards and connection conditions, a medium-voltage transformer is not absolutely necessary.

Additionally required material (not included in the scope of delivery):

  • Protective grease (only for conductors made of aluminum)

Procedure:

  1. Ensure that the AC miniature circuit breaker is switched off and that it cannot be reconnected.
  2. Shorten the cable if necessary.
  3. Dismantle the cable.
  4. Strip the insulation on the insulated conductors each by 30 mm.
  5. Remove any cable remnants from the product.

  7. Connect PE, L1, L2 and L3 to the terminals according to the label. To do so, position each conductor as far as they will go into the corresponding terminal and tighten the screw of the terminal (AF 8, torque for conductor cross-section 50 mm² to 95 mm²: 20 Nm; torque for conductor cross-section 120 mm² to 150 mm²: 30 Nm).
  8. Ensure that the correct conductors are assigned to the terminals.
  9. Ensure that all conductors are securely in place.
  10. Firmly tighten the swivel nut on the cable gland.
