6. Initial operation
6.1 Place of installation
The unit should not be exposed to moisture, welding spatter and the direct ray of sparks at
grinding works.
6.2 Mains connection
Fit a power plug to the mains cable as indicated on the rating plate. The 3 phases (black,
brown, blue) may be connected to L1, L2, L3 as you like.
4.3 Connecting the compressed air
Connect compressed air supply by rapid action hose coupling at the backside of the unit.
The mounted filter pressure reducer regulates the connected comressed air supply to the
correct working pressure. Pay attention to a sufficient pressure and a sufficient flow
quantity of the pressure air supply. Besides the air must be as free as possible from oil
and water.
Warning!
The water tanks must be emptied periodically.
The water tank empties automatically itself, when the air system
becomes pressureless. If the machine is fixedly connected to a
compressed air supply being continously under pressure, the machine
must be separated from the compressed air supply to empty the water
tank.
4.4 Connecting the torch
The cutting torch is already connected to the unit in factory. Both parts are tested and
delivered as one unit.
If the cutting torch must be exchanged later on, an expert must take off the housing
bonnet and connect tightly the new torch at the corresponding connections. The blade
terminals of the torch trip line may be pluged into the trip line socket as you like.
Warning!
Pull power-supply plug prior to opening the casing of the plasma unit.
