Use HC housing h >= 72 mm. Connection of the wires using a 4 mm. Allen wrench.Axial screw connection only for stranded wires.Plug-in connections may only be operated only when there is no load/voltage.
Note for axial connection method The specified conductor cross sections refer to the geometric cross section of the used conductor.The use of conductors with a geometric cross section that deviates greatly from the nominal cross section of the conductor should be checked first.The wiring space of the axial screw technology has been designed for fine strand conductors as per VDE 0295 class 5. Deviating conductor superstructures (e.g. class 6 conductors) must be checked before use.Connection It must be ensured before installation that the ball screw is completely turned back (chamber is open). Twisting the conductors is not allowed. The cores must be pushed up to the end of the contact chamber (until the contact is insulated). Keep the core in this position and tighten it using an Allen key. The required core end must be cut before a reconnection. Tightening the connection screw is allowed only once in order to prevent a breakage of the litz wire.
