3.5 Maximum active bar length and length of the high voltage cable
Both the lengths of the high voltage cable and of the active bars are
limited. The shielded high voltage cables cause a capacitive load on the
transformer inside the power supply. The maximum loading capacity is a
result of the function of the total active bar length and the total length of all
high voltage cables. Fig. 4 demonstrates this principle for R5x bars, ion
blower nozzles R36E, ion blower heads R55E and ion bower pistols PR36
and PR55.
Example: The maximum permissible total cable length with a 3 meter
active bar length is 32 meters.
Fig. 5 demonstrates this principle for R47 and R6x bars.
