bus bar. This reduces chances of ingress by pollutants and minimizes heating of the head
electronics by the bus.
For rising (“vertical”) busses, the head interconnection cables may be located on any side of
the bus, depending on mechanical and thermal considerations. Avoid mounting elbows with
cable assemblies above vertical bus. The head should be mounted so conventional (+) to (-)
current flows in the direction of the arrow on the Measuring Head.
The following tools and materials may be required for installation:
Materials marked with an asterisk ( * ) are included with each LKAT Plus System order.
34” (864mm) Releasable Cable Ties *
Silicone RTV adhesive / sealant *
1/8” (3mm) hex wrench *
Drill, drill bits, mounting hardware, screwdrivers, wrenches, etc.
Cable puller, cable ties, ladder, etc.
The following is the recommended sequence for installing the Measuring Head:
1. Refer to the Outline and Mounting drawing for the Measuring Head at the end of this
manual.
2. Determine the position where the Measuring Head will be installed. Bus bar(s) should be
free from grease and dust for the best adhesion of the LKAT mounting channels to the
bus bar(s).
3. Connect the head cable assemblies to the Metering Unit.
4. Remove the backing from the adhesive foam strips on the fiberglass mounting channels.
Position the mounting channels to the bus in the desired location.
5. Squeeze a ¼” (6.5mm) continuous bead of silicone RTV adhesive around the elbow and
tube seam indicated by the yellow “HEAD SPLITS HERE” marker. Keep the Silicone RTV
on the outside of the elbow cavity. There must be sufficient Silicone RTV adhesive to
seal any gap between the Measuring Head halves.
6. Position the two “L-shaped” head halves around the bus and the fiberglass channels.
Mate the two halves, pressing them together until the tubes bottom out on the elbows.
7. Install the releasable cable ties to hold the head halves together while the Silicone RTV
cures. The cable ties may be removed after 24 hours.
8. Route the head interconnection cables away from the bus and other high voltages.
9. Connect the power cable assembly to appropriate power source and LKAT Plus Metering
Unit.
10. The Silicone RTV takes approximately 24 hours to cure. After Silicone RTV has cured,
the plunger tension may be adjusted, if needed. Use the 1/8” hex wrench supplied with
the system for this purpose.

METERING UNIT INSTALLATION
The location of the metering unit should be determined by the following factors:
1. Ambient air temperature must stay in the specified range at all times.
2. The location should not be exposed to direct sunlight.
3. The location should be within reach of the head cables supplied with the system.
Standard head cable length is 33 feet (10 meters). Extra-long head cables may also be
ordered for special applications.
