Connection To Ground Cable - Telwin SPL 60/3 Manual De Instrucciones

phase distribution systems by means of a "PE" protection
earth plate.
- Arrange a line with normalized plug protected by a
differential automatic switch; verify that the plug terminal is
connected to the ground of the distribution network.
- The data for the dimensioning of the feeding line (power,
capacity) are desribed on paragraph "Technical data".
- Before any connection check that "U" rating matches the
tension and frequency of the network on site:
WARNING !
THE MACHINE IS ARRANGED BEFOREHAND IN
FACTORY WITH THE HIGHEST TENSION OF THE
RANGE, EX.:
U 230V

400V
- THREE PHASE LINE 230 V
Reach change tension board by releasing the
machine covering and reset connections so that what
is shown by the rating matches with the available
tension.

WARNING !
IN CASE LINE TENSION AVAILABLE IS LESS THAN:
375 V OR RESPECT : 215 V
WE RECOMMEND TO ADEQUA TE THE PRIMARY
CONNECTION TO THE MAIN TRANSFORMER.
Reach primary connection board by opening right hand
side panel of the machine.
MOVE FEED CABLES OF TRANSFORMER FROM
TERMINAL X1-Y1-Z1 TO THE RELATIVE TERMINALS
X-Y-Z.

PAY ATTENTION THAT THE YELLOW/GREEN
CONNECTOR OF THE CABLE ARE PROPERL Y
CONNECTED TO THE TERMINAL OF THE PLUG.

CONNECTION TO GROUND CABLE

- Connect the pliers terminal of ground to the part to be cut
or to the metal bank observing the following precautions:
. VERIFY THAT THERE IS A GOOD ELECTRIC
CONTACT P ARTICULARLY IF
OXIDA TED COATED SHEETS ARE CUT.
. MAKE GROUND CONNECTION AS CLOSER AS
POSSIBLE TO CUTTING AREA.
. IF METAL STRUCTURES ARE USED WHICH ARE
NOT PART OF THE OBJECT BEING
RETURN WIRES FOR THE CUTTING CURRENT ,
THIS MAY BE DANGEROUS
INSUFFICIENT RESULT WITH THE CUTTING.
. DO NOT MAKE A GROUND CONNECTION IF THE
PART HAS TO BE REMOVED .

CONNECTION OF PLASMA CUTTING
TORCH.
- The TORCH model HP 50 is supplied already
connected to current source SPL 60/3 through an
inside connection, no further operation is then necessary
before starting it.
- Torch model HP 150 For current source SPL 90/3 and
SPL 150/3 insert male connector of the torch into
centralized connector on the front panel of the machine,
being careful that polarization key laps.
Screw tightly clockwise the ring nut to ensure that the air
flows without leaks.
WARNING !
Before starting with cutting operations verify that the parts
are properly assembled by inspecting the head of the torch
as shown on paragraph "TORCH MAINTENANCE".
LOCATION AND HANDLING OF SOURCE
OF CURRENT
- Choose location verifying that there is a good change of
air and no dust, smoke or gas is present.
- Make sure that obstacles do not prevent the cooling air
flow out of front and rear openings of the machine.
- Arrange an open space of at least 500 mm. around the
machine.
- In case the machine has to be moved always disconnect
the plug from the outlet and gather the cables and pipes so
as to avoid that may be damaged.
- DO NOT LIFT THE MACHINE BY MEANS OF
HEANDLES, whose function is exclusively to move the
unit on the wheels.
- If the machine must be lifted always use 2 straps each
having a capacity at least twice the weight of the machine.
The straps must be positioned as follows.

- In position 1 (ON) the machine is ready for functioning and
signal light is on.
- Control and duty circuits are fed but there is no tension
present in the torch (STAND BY).
- In position 0 (OFF) any functioning is inhibited, control
devices and signal light are off.
2 RANGE SELECTOR.
- It allows to set the intensity of cutting current supplied by
the machine according to the use (thickness of
material/speed). See TECHNICAL DA TA for proper
relation of intermittence on/stand by to be adopted
according to selected range. (period = 10 min.).
