SECTION 3 — INSTALLATION
3.1 Siting the RT4000/RT5000
Site the RT4000/RT5000 on a clean dry sur-
•
face, preferable above ground level.
Make sure there is at least 20cm clearance
•
at the front, rear and right side of the ma-
chine to allow good circulation of the cool-
ing 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 that particles created by grind-
ing and cutting operations do not enter the
machine.
Note! Damage caused by metal particles and
water entering the machine will not be cov-
ered under warranty.
3.2 Connecting to mains supply
WARNING! All electric shocks are potentially
fatal, a competent electrician should carry
out the fitting of the mains plug.
Make sure that the mains supply is of the
•
correct voltage and current capability for
the machine.
Make sure that any extension cables 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 carrying capacity. If the
machine is wired directly to the mains sup-
ply then an isolator switch must be fitted.
Note! See the technical specifications page for
correct supply information
Primary cable length
Long cable lengths may reduce the perform-
ance of the machine, the welding arc may
become unstable, especially at higher cur-
rents. Ensure the mains cable is not coiled up
during welding as this will reduce the input
voltage to the machine and may cause over-
heating and degradation of the cable.
3.3 Setting supply voltage tapping
WARNING! All electric shocks are potentially fa-
tal, a competent electrician should carry out any
supply voltage tapping adjustments required.
To enable the setting of the supply voltage
•
tapping, the cover of the RT4000/RT5000 has
to be removed.
The photograph below shows the voltage tap-
•
ping set to 415V, with the red wire from the
fuse holder connected to the 415 terminal.
This connector can be moved to the required
•
voltage terminal to select the desired input
voltage.
