Strip the conductors.
• Take care not to damage the cable shielding.
• Take care not to damage the cable cores.
Insert the cables into the enclosure.
• Route the cables through the cable entries
into the enclosure.
• Tighten the cable entries.
• Note the tightening torque.
Strip the conductor.
• Stripping length: 7 mm
• Take care not to damage the conductor.
Insert the conductor into the terminals and
clamp in place.
• Press on the core end sleeves using a
suitable tool.
• The conductor insulation must reach to the
