INSTALLATION
Safety Precautions
CORRECT OPERATIONAL USE
The machine should be located in a clean dry place where
there is free circulation of clean air such that air movement
in through the front and out through the back will not be
restricted. Dirt and dust that can be drawn into the machine
should be kept to a minimum.
Failure to observe these precautions can result in
excessive operating temperatures and nuisance shutdown
of the machine.
LIMIT ON STACKING
The units may be stacked three high by observing the
following safety precautions.
A. Make sure the first or bottom unit is setting on a level,
well supported surface.
B. The units must be stacked with their fronts flush,making
sure the two holes in the base rails of the unit being
stacked on top are over the two pins located on the top
front corners of the unit it is being stacked on.
Input Power Connections
Only a licensed electrician should connect the input leads
to the DC-400.
Connections should be made in accordance with all local
and national electrical codes and the connection diagram
located on the inside of the input access panel cover.
Failure to do so may result in bodily injury or death.
By removing the rear access panel the three phase input
power is connected to the three line terminals on the input
contactor, and the earth lead to the earthing terminal on the
input box floor marked with the symbol.
Output Cable Connections
The output leads are connected to the output terminals
marked “+” and “-”. They are located at the lower right and
lower left corners of the front panel. Strain relief for the
electrode and work cables is provided by routing the leads
through the elliptical holes in the base before connecting
them to the output terminals. Lift the output stud cover to
gain access to the output studs. Lower stud cover after
connecting output leads.
