R2500
SECTION 3 — INSTALLATION
3.1 Siting the R2500
•
Site the R2500 on a clean dry surface, preferable
above ground level.
•
Make sure there is at least 20cm clearance at the front,
rear and right side of the machine to allow good circu-
lation of the cooling air.
•
Protect the machine from heavy rain and if used in hot
climates, against direct sunlight.
•
Ensure that the machine is positioned in such a way so
that particles created by grinding and cutting opera-
tions do not enter the machine.
Note! Damage caused by metal particles and water
entering the machine will not be covered under war-
ranty.
3.2 Connecting to mains supply
WARNING! All electric shocks are potentially fatal, a
competent electrician should carry out the fitting of
the mains cable and plug.
•
Make sure that the mains supply is of the correct volt-
age and current capability for the machine.
•
Make sure that the mains cable and any extension ca-
bles used are of sufficient current carrying capacity.
•
Make sure that the mains plug and socket (if fitted) are
in good condition and are of the correct current carry-
ing capacity, if the machine is wired directly to the
mains supply then an isolator switch must be fitted.
Note! See the technical specifications page for cor-
rect supply information.
Primary cable length
Long cable lengths may reduce the performance of the
machine, the welding arc may become unstable espe-
cially at higher currents. Ensure the mains cable is not
coiled up when you are welding as this will reduce the
input voltage to the machine.
•
Strip approximately 150mm of insulating sheath off the end
of the mains cable, strip back the insulation on the four
cores of the cable to a depth of 8mm.
•
Attach the three phase cores to terminals L1, L2 and L3 on
the mains input PCB as shown; using 2.5mm x 6.3mm insu-
lated spade connectors, and attach a 2.5 x 5mm ring ter-
minal to the earth core and connect it to the earth stud,
bolting the terminal down firmly.
•
Clamp the cable by tightening the screws on the integral
cable grommet/clamp. This must clamp down the external
insulating sheath of the cable and not the four cores.
When connecting mains cable refer to photo of mains
input connection below:
1 Cable In -
Combined cable entry and clamp.
2 Earth -
Welded earth stud.
3 Primary Connections -
L1, L2 and L3.
4 Voltage Selection -
Wire for voltage tapping, shown set
for 415V. Can also be set for 380V or 460V by moving the link
wire to the relevant terminal. Voltages are marked on the
PCB.
NOTE! Never attach link wire to the 220V terminal.
