Control and Monitoring Connector
All the polarity inverter models have the same Control and Monitoring connector
mounted on the rear panel and labeled as C1 (see
Figures Figure

).
The chosen connector is the Connitek CKB4102A18-1SG1T50 and the mating
connector use with the cable is CKB3106AF18-1PT50.

Figure 13: C1 connector with pinout (right table).
With reference to Figure 13 Error! Reference source not found., the following
information on the Pinout are provided:
1. to allow the commutation of the polarity inverter, pins D and E must
form a closed path; If pins D and E are not connected any change in pins
A, B and C will have no effect at all;
2. when pin A and B form a closed contact, the polarity inverter works in
direct polarity. It is highly recommended to use a single relay to switch
between pins B and C;
3. when pin A and C form a closed contact, the polarity inverter works in
inverse polarity. It is highly recommended to use a single relay to switch
between pins B and C;
4. when the polarity inverter is working correctly and the internal relay is
seated to be Direct or Inverse polarity, pins F and G form a closed
contact. These pins can be used to generate an interlock status in order
to turn off the power supply when pins F and G form an open contact;
