For more details see 667/GA/32600/000 sheet 2 in Appendix B. The current sensor
should be mechanically secured by passing a tywrap or equivalent through the sensor
hole and around a suitable fixing point.
The sensors may produce a high voltage when current is passed
through the core if they are not terminated into an I/O Board.
The sensors are terminated with Berg Mini PV terminals and are clipped into a Berg
mini latch housing, to provide a complete sensor assembly...
