Installation - NewArc R4000cc Operational Manual

2. Installation

Unpacking
Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging
until the installation is complete.
Positioning of the machine
Position the R4000/R5000 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 grinding and cutting
operations do not enter the machine.
NOTE! Damage caused by metal particles and water entering the machine will not be covered under
warranty.
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 supply 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 perfor-mance 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.
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 front panel display cover of the R4000/R5000
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.
