Earthing - Stel TIG μP 261H 1f Manual De Instrucciones

TIG µP 261H - 263H
TECHNICAL DESCRIPTION
The good operation of the generator is ensured by correct installation; you must
therefore proceed as follows:
- Position the machine in such a way that there is no obstacle to the air circulation
ensured by the internal fan (the internal components require suitable cooling) (see
chap. 7.1 page 33) .
- Ensure that the fan does not send deposits or dust into the machine.
- Avoid impacts, rubbing, and - absolutely - exposure to dripping water, excessive
heat sources, or any abnormal situations.
MAINS VOLTAGE
The generator works at mains voltages differing by 20% from the rated mains
value of 400V (Minimum voltage 320V, maximum voltage 480V).
CONNECTION
- Before making the electrical connections between the current generator and the
line switch, ensure that the switch is turned off .
- The distribution panel must comply with the regulations in force in the country of
use( )
- The mains system must be of the industrial type.
- Provide a special socket for housing the leads of the power supply cable (200A:
with section 4mm).
- For longer cables, increase the section of the lead accordingly.
- Upstream, the special mains socket must have a suitable switch with delayed
fuses.

4.2– EARTHING
- To ensure user protection the welding machine must absolutely be correctly
connected to the earth system (INTERNATIONAL SAFETY REGULATIONS).
- It is indispensable to provide good earthing by means of the yellow-green lead in
the power cable, in order to avoid discharges due to accidental contacts with
earthed objects .
- The chassis (which is conductive) is electrically connected with the earth lead; if
the equipment is not suitably connected to earth it may cause electric shocks
which are dangerous for the user.
