Instructions on how to connect a line supply cable to the connection plug is provided below.
As standard, the protective conductor is connected at the connection plug. If this is not
possible in your installation, for example due to space constraints, you may instead connect
the protective conductor to the protective conductor connection at the component, see
Chapter "Connect the protective conductor (Page140)". In this case, in the following, it is not
necessary to connect a core for the protective conductor connection at the connection plug.
Proceed as follows to connect the cores in the connection plug:
1. Insert the cores into the open terminals starting with the protective conductor, W1, V1 and
U1.
– The cores must be inserted as far as they will go.
– For larger cross-sections, it is helpful if the protective conductor, W1, V1 and U1 are
simultaneously inserted and secured by screws.
2. Tighten the screws. Slotted screwdriver 1.0 x 5.5 mm. Tightening torque: 1.2 - 1.5 Nm (18 lbf
