INSTALLATION
WARNING: This
Class A
equipment is not
intended for use in residential locations where the
electrical power is provided by the public low-
voltage supply system. There may be potential
difficulties
in
ensuring
electromagnetic
compatibility in those locations, due to conducted
as well as radiated disturbances. This equipment is
comply with
IEC 61000-3-12
and
It can be connect
to a public and private low voltage system. The
good operation of the machine 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 since the internal components require
suitable cooling.
- Ensure that the fan does not send deposits or
dust into the machine.
- Avoid impacts, rubbing, and – absolutely no
exposure to dripping water, excessive heat
sources, or any abnormal situations.
MAINS VOLTAGE
The machine operates from a mains voltages
differing by +/-30% from the rated mains value
(example: 230V rated, Minimum voltage 160V,
maximum voltage 270V).THOR 41K Fuse 16A T
CONNECTION
- Before making the electrical connections between
the Inverter 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.
- When using long extension cables, the core
diameter section is increased as required for
optimum performance.
- The power input supply socket must have a suitable
switch provided with #slow burning' type fuse(s).
- In the event of damage to the power cable,
replacement or repair must be performed by a
qualified person at an approved service centre.
EARTHING
- To ensure user protection the Inverter must by
law be correctly connected to the earth system
(INTERNATIONAL SAFETY REGULATIONS).
- It is indispensable to provide good earthing by
means of the yellow-green wire 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 wire; if the equipment is
not suitably connected to earth it may cause
electric shocks which are dangerous to the user
and those nearby.
PNEUMATIC CIRCUIT CONNECTION:
The THOR uses compressed air for plasma
cutting. Any cylinder of compressed air may
therefore be used, or air from a compressor. The
air must be free from polluting particles, such as oil
or other contaminating agents. A pressure
regulator is provided to ensure the correct air flow
rate on the torch.
KEY:
1– Air filter
2– Reducer (pressure regulator)
3– Pressure gauge
4– Pressure switch
5– Solenoid valves
A pressure higher than 5 bar (5-5.5 bar) must be
applied to the air filter located on the rear panel of
the THOR (100l/min). The pressure must not
exceed 6 bar. The pressure regulator 1 is set by
the manufacturer at 4.8 bar. Check the pressure by
pressing the Air Test button on the front panel and
check that the pressure gauge gives a reading of
4.8 bar. If it should be necessary to regulate the
pressure, refer to the regulating procedure in the
TROUBLE SHOOTING section.
Pay
particular
attention
to
the

connection cables. Any blockage of the tubes or
