Electric Shock Prevention
The ProLine 2200 system uses high open circuit voltages that can be fatal. Extreme care
should be used when operating or performing maintenance on the system. Only qualified
personnel should service the ProLine system. Observe the following guidelines to protect
against electric shock:
•
A wall-mounted disconnect should be installed and fused according to local
and national electrical codes. The disconnect should be located as close as
possible to the power supply so it can be turned off in case of an emergency.
•
The primary power cord should have a 600 volt minimum rating in order to
protect the operator. In addition, it should be sized according to local and
national electrical codes. Inspect the primary power cord frequently. Never
operate the ProLine system if the power cord is damaged in any way.
•
Make sure the primary power ground wire is connected to the input power
ground stud on the ProLine power supply. Make sure the connection is
securely tightened.
•
Make sure the positive output (work ground) of the ProLine power supply is
connected to a bare metal area on the cutting table. A driven ground rod
should be placed no further than five feet from this connection. Make sure
this ground point on the cutting table is used as the star ground point for all
other ground connections.
•
Inspect the torch leads frequently. Never use the system if the leads are
damaged in any way.
•
Do not stand in wet, damp areas when operating or performing maintenance
on the system.
•
Wear insulated gloves and shoes while operating or performing maintenance
on the system.
•
Make sure the ProLine system is switched off at the wall disconnect before
servicing the power supply or torch.
•
Never change torch consumable parts unless the ProLine system is switched
off at the wall disconnect.
•
Do not attempt to remove any parts from beneath the torch when cutting.
Remember that the workpiece forms the current path back to the power
supply.
•
Never bypass the safety interlock devices.
•
Before removing any of the ProLine covers, switch the system off at the wall
disconnect. Wait at least five (5) minutes before removing any cover. This
will give the capacitors inside the unit time to discharge. See Section 5 for
additional safety precautions.
•
Never operate the ProLine system without all of the covers in place. See
Section 5 for additional safety precautions.
•
Preventive maintenance should be performed daily to avoid possible safety
hazards.
