For more details see 667/GA/26580/000 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.
