Setting the Frequency of Polarity Reversal:
Via a quadruple switch S2 located on the printed circuit breaker 8 different frequencies of
polarity reversal can be selected.
The frequency of polarity reversal in the default setting is 1,5 Hz. Any changes in the default
setting of the frequency of polarity reversal may be indicated on the label of the front panel
of the device (see Figure 1) making a cross on the corresponding frequency value.
The following figure is a partial view of a module pulled out of the housing. Position and
designation of the relevant switches can also be learned from this illustration.
