(head top half to bottom assembly) Never exceed 14 N.m (125 lb. in.)
NOTE
The Measuring Head window insulation rating is directly proportional to the clearance of the
Measuring Head to the bus. For instance, a bus in direct contact with the window insulation of
the Measuring Head will have an insulation rating of 6kV. A clearance of 1" increases the
window insulation rating to 12 kV. Thus, the greater the distance through the air between the
bus and the head, the greater the insulation rating will be.
