the unit is lower or equal to 0,093 (art. 369), 0,044 (art. 370),
0,031 (art. 371) at the interface point between the user unit
and the mains.
Is responsibility of the installer or user of the equipment
to ensure, possibly referring with the operator of the dis-
tribution network, the equipment is connected to a power
supply with admitted maximum system impedance Zmax
lower or equal to 0,093 (art. 369), 0,044 (art. 370), 0,031 (art.
371).

Commands and fittings (fig. 4)..

BA Negative output terminal (-). Connect the TIG torch
power cable.
BB Positive output terminal (+). Connect the earth ca-
ble connector (workpiece potential).
BC External commands connector. The available sig-
nals are described in par 4.4.
BD Gas fitting. Connect the TIG Torch gas pipe.
BE Main switch. Main switch of the Welding System,
thus Power Source, Control Panel, Wire Feeder and
Robot Interface (not including the Robot manage-
ment part).
G
BG Power cord.
B
BH Gas fitting. Connect the gas pipe supply.
BO Connector. DB9 type connector (RS232 serial line)
to use for Welding System programs updating (Power
Source, Control Panel, Wire Feeder Unit and Robot
Interface).
BP Fuse holder. Fuse inserted on Cooling Unit power
supply (T 1,6A/400V - Ø 6,3x31,8 mm).
BQ Cooling Unit socket. Connect the Cooling Unit sup-
ply cable.
BR Pressure switch socket. Connect the Cooling Unit
pressure switch cable.
BS USB Connector. Be used to update the Welding Sys-
tem firmware (Power Source, Control Panel, Feeder
Unit and Robot Interface).
CN1 CAN-1, CAN bus connector. Connect the Power
Source – Feeder Unit extension (2) services cable.
CN2 CAN-2, CAN bus connector. Connect the Power
Source – Robot Interface or Robot Control cable (3).
CN3 "External Stop" connector (option art. 426).
Connect any external devices for stopping the Power
Source.
The "External Stop" signal is exclusively provided as
quick stop to protect the machine.
For a person's additional protection must be used an ap-
propriate emergency stop system.
CN4 Connector "Arc voltage output" (optional).
Is the power source output voltage picked up directly
from BB and BA output terminals, without galvanic
insulation (output impedance = 1,1 Kohm).
