Changing the Output Polarity

Each  channel  on  the  Terranova®  752A  can  be  independently  set  to  output  either  positive  or 

negative high voltage.

User should wait at least 15 seconds after turning OFF the 

Terranova® 752A before removing the power cord

WARNING! 

Figure 4. 

Component position for positive voltage output

To change the output polarity:

1.  Turn unit OFF via the 

POWER

 switch

2.  Remove power cord and ion pump cable(s)
3.  Remove the six #6-32 screws along the edge of the top cover
4.  Carefully lift the top cover and disconnect the fan plug
5.  Remove top cover
6.  Locate and identify the proper HV board for CHANNEL 1 or CHANNEL 2
7.  Locate the HV diode. As shown in 

Figure 4

, the HV diode is the electrical component 

identified by the arrow.

8.  Remove the two #6-32 screws to uninstall the HV diode
