3.4 Installation of the charging bar
To avoid creepage currents which may damage the charging bar and the
mounting material, attach the charging bar with insulating mounting
material.
The length of the current creepage path (= shortest distance along a
surface between the tip of the charging bar and ground) depends on the
maximum operating voltage of the charging bar.
Applications: tacking protective foil, laminating decorative substrate etc.
