Precedence:
This specification takes precedence over documents referenced herein.
Effectivity:
Reference documents shall be the issue in effect on the date of invitation or bid.
CAUTION:
Operation beyond the rated voltage or current may result in rupture, electrical arcing or flame.
When using a test probe to probe either of the two test points on the top of the device, care should
be taken to avoid puncturing through the insulating material of the device, as this can result in
shorting out the terminals which can cause electrical arcing or flame.
