The connections consist of either 4 or 5-conductor cables, as specified by the electricity company.6
4-conductor connection 6
For the 4-conductor connection, the neutral (N) and protective earth (PE) conductors are com-
bined in a common wire PEN. 6
Å Insert the yellow-green wires BR3 and BR4 between the N and PE terminals in the right-hand
terminal panel of terminal strip X206 (see Fig. 6 - 1).
5-conductor connection 6
For the 5-conductor connection, the neutral (N) and protective earth (PE) conductors run in sep-
arate wires. 6
Å Remove the yellow-green wires BR3 and BR4 between the N and PE terminals in the right-
hand terminal panel of terminal strip X206 (see Fig. 6 - 1).
