C for "control" and F for "focus".  These pins can be ignored and cut off.

There should be a ground and the other two are input and ouput.   Hook up to
a 120 V variac.  If you get the input and output reversed you will have no
360 VDC output.  It will block so you can not hurt it.

Use caution in your final application as most of these rated 1 mA output
current.
