2.3 Safety instructions
For your safety, before connecting the source to the line, closely follow these instructions:
- an adequate two-pole switch must be inserted before the two-pole main outlet; this
switch must be equipped with time-delay fuses and it must match the data specified
in the chapter "Technical Specification";
- the mono-phase connection with ground must be made with a two-pole plug compatible
with the above mentioned socket;
- two wires of the two-pole input cable are used for the connection with the mono-
phase line and the yellow-green wire for the compulsory connection to the ground in
the welding location;
- connect all the metal parts which are near the operator in the welding location by
using cables bigger or of the same cross section of the welding cable to a ground
terminal;
- when working in a confined space, the power source must be kept outside the
welding area and the ground cable should be welded to the workpiece; do not work in
a damp or wet area in these conditions (Fig. 7).
