Balancing the cutting head
Before making the electrical connections, the head return springs must be
tensioned to balance the cutting head weight. Using a 10 mm. wrench, tighten the
screws until the distance between the first coil of the spring and the bracket is 8
mm.
Connection to the power supply
Before connecting the machine to the power supply, check that the socket is not
connected in series with other machines. This requirement is fundamental for the
good operation of the machine.
To connect the machine to the power supply, proceed as follows:
"
connect the power supply cable of the machine to a plug which matches the
socket to be used. (EN 60204---1; par. 5.3.2)
CONNECTION FOR ”5-CORE” WIRE SYSTEMS WITH NEUTRAL
R = L1
S = L2
T = L3
PE = GND
N = NEUTRAL
CONNECTION FOR ”4-CORE” WIRE SYSTEMS WITH NEUTRAL
S = L2
T = L3
PE = GND
R = L1
When using systems with a neutral wire, special care must be taken when con-
necting the blue neutral wire, in that if it is connected to a phase wire it will dis-
charge the phase voltage to the equipment connected for voltage: phase--
neutral.
