4.1 HANDLING PRECAUTIONS
LKAT
2
Systems should be handled with the same care as any precision measuring
instrument. Severe jolts or bumps to the Measuring Head or Metering Unit may cause
movement of internal parts, and possibly a malfunction.
Personnel involved in the
installation should be familiar with the technical terms, warnings, and instructions in
this manual, and all plant safety rules, and be able to follow these.
The complete system should be inspected for shipping damage at the earliest opportunity.
Visible damage must be reported to the carrier immediately. Concealed damage (not evident
until the system is operated) must be reported to DynAmp, LLC immediately.
4.2 INSTALLATION CONSIDERATIONS
Read the following before mounting the head:
1. The Measuring Head is designed to be installed on high voltage bus bars. All
interconnection cables must be safely routed away from bus bars and high voltages. Do
not allow any interconnection cable to contact bus bars or high voltages. Ignoring the
installation precautions and warnings can result in severe personal injury or equipment
damage.
2. Always follow all local and plant safety procedures when the unit is to be installed on a live
bus.
3. Choose a mounting location for the head where the ambient air temperature does not
exceed the specified temperature limits. The LKAT
2
Measuring Head may be located in-
doors or outdoors, but should be kept away from extreme heat and solvents. Head
installations in direct sunlight are not recommended, as excessive temperature rise could
result in measurement error or damage to the head enclosure. If the head is to be
installed in an especially harsh environment, please contact the factory to discuss special
requirements.
4. No part of the head or Metering Unit should be submerged under water.
5. The head must be installed with proper polarity. An arrow indicates the direction that
conventional bus current must flow through the aperture (+) to (-). No damage will occur if
the head is reversed, but the system output will indicate current flow in the reverse
direction.
6. Measuring Heads are shipped in matched halves. Make sure that the same serial number
is present on both halves of the Measuring Head and the Metering Unit. The two head
halves should mate squarely and evenly without forcing or twisting.
7. The Measuring Head is not grounded; however, the head cables should be disconnected
from the Metering Unit prior to installation or maintenance to minimize the possibility of
electrical shock.
8. Measuring Heads are shipped with mounting hardware. The mounting screws may require
adjustment for appropriate position and holding force on the bus. Refer to Outline &
Mounting – LKAT

Measuring Head drawing.
Whenever possible, the head should be installed on the longest straight run of the bus that is
available in an area free of other bus structures. The status accuracy diagnostics LEDs and
relay contacts indicate proper operation in a given head location.
