5.6.6 5 or 4-wire connection for the power supply
The connections are produced using either 5 or 4 wires, according to the electricity company's re-
quirements. The placement machine is supplied with a 5-wire connection as standard. 5
5.6.6.1 5-wire connection
In the 5-wire connection, the neutral conductor (NE) and protective earth (PE) consist of separate
wires. 5
Two additional yellow-green jumper cables BR1 and BR2 are connected to terminal strips
X206:PE and X207:7 in the "Voltages" terminal panel. These jumper cables are then recon-
nected for a 4-wire connection.
