Before actually installing the Measuring Head on the bus, the head may be checked for
damage to the head and performing a head resistance check per Table 4.1 first, if desired.
This is accomplished by connecting the cables with the head removed from the bus. After
the procedure is complete, the Measuring Head should be mounted as according to the
instructions in this section, “Installation Considerations” section 4.4.
Check the mating faces of the Measuring Head. Make absolutely certain that the serial
numbers of both halves of the Measuring Head match, otherwise you may cause
misalignment and unit failure. Use only a small brush or cloth to remove any dirt particles
from the Measuring Head part-line insulation, multi-conductor connector and latch areas.
NOTE
When installing the Measuring Head, protect the window insulation from impact, and
do not let the weight of the Measuring Head rest upon the window insulation as it can
be easily damaged. Also, the interconnecting cable is of top quality, but it is not
armored. Protect it from abrasion and sharp edges.

Typical For LKP Series Measuring Heads
The Measuring Head must be installed with current arrows in the same
direction as conventional current flow in the bus. No damage will occur if the
Measuring Head is reversed, but the system will not produce an output.
