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 does not comply with
IEC 61000-
3-12
. If it is connected to a public low voltage
system, it is the responsibility of the installer or
user of the equipment to ensure, by consultation
with the distribution network operator if necessary,
that the equipment may be connected. 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 Inverter operates from a mains voltage supply:
THOR 123 400V +/- 15% and Fuse rating di 25A
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 pneumatic
connection cables. Any blockage of the tubes or
excessive lengths may cause problems during the
cutting process.
A pressure switch set at 3 bar inhibits operation
when the pressure at output of the reducer is
insufficient to guarantee operation.
