3.8.6 4 or 5-wire connection for the power supply
The connections are produced using either 4 or 5 wires, according to the electricity company’s
requirements. 3
4-wire connection 3
In the 4-wire connection, the neutral conductor (NE) and protective earth (PE) are combined to
form a single PEN wire. 3
Å Insert the yellow-green wires BR3 and BR4 between the N and PE terminals in the right-hand
terminal block on terminal strip X206 (see Fig. 3 - 12
).
5-wire connection 3
In the 5-wire connection, the neutral conductor (NE) and protective earth (PE) consist of separate
wires. 3
Å Remove the yellow-green wires BR3 and BR4 from between the N and PE terminals in the
right-hand terminal block on terminal strip X206 (see Fig. 3 - 12
).
