5-12. Secondary Insulation Protection
!
Connect supplied ground
lead(s) between the
workpiece and power source
to provide proper secondary
insulation protection from a
short in the output circuit.
For single output, only one
ground lead is required. For
dual output , use both ground
leads.
Secondary insulation protection
circuitry automatically shuts down
the power source output if a
potentially hazardous condition
exists at the heating device
connected to the power source (e.g.
insulation has broken down on a
heating blanket causing the
conductor to come into contact with
the workpiece or a heating coil
touches the workpiece causing a
short in the output circuit).

metal (free from rust, paint,
grease, etc.).
