SETTING UP
7.
CONNECTION TO THE MAIN SUPPLY
The power source must be connected to a single-phase 230V or 110V - 50 Hz/60 Hz mains + ground with a
tolerance of +/- 13%.
It has built-in over voltage protection (if the power supply is 110V) which allows engine driven generator supply
Main supply must be protected by fuses or circuit-breaker according to the value I1
eff
written on the specifications
of the power source.
It is strongly suggested to use a differential protection for the operator’s safety.
8.
CONNECTION TO THE GROUND
For the operator's protection, the power source must be correctly grounded (according to the International
Protections Norms).
It is absolutely necessary to set a good ground connection installation with the green/yellow leading of the power
cable. This will avoid discharges caused by accidental contacts with grounded pieces.
If no earth connection has been set, a high risk of electric shock through the chassis of the unit remains possible.
9.
PRELIMINARY PRECAUTIONS
For the good operation of your welding power source, make sure that the air flow produced by the fan inside the
unit is not obstructed.
Also try to operate in a non-dusty area.
Avoid all impacts, exposure to damp areas or excessive temperatures.
