The cable is passed through the tightening neck and sealing O-ring. The veins need to be suitably shortened, stripped and shaped. After the cores have been inserted into the central part of the jumper, the screws (cross head) are fixed and the tightening neck is properly tightened.
The design has an IP68 degree of protection, i.e. withstands immersion in water. The actual material from which the jumper is made shows excellent resistance to mechanical damage or various chemicals. It is permanent, does not age and its properties do not change depending on the surrounding atmospheric conditions.
This is a classic jumper of two CYKY 5-wire cables commonly used in the field.
It is typical to use a jumper for luminaires with DALI control, where 3 wires are reserved for power supply and 2 wires for DALI control.
