- Ensure Safety and Perform Initial Checks
DANGER: De-energize all apparatus in the work area before beginning installation or removal of parts. Do not touch or move energized products. This product must be installed only by competent personnel trained in high voltage electrical safety practices. Read all instructions thoroughly. Inspect all package contents for completeness and damage. Verify all components fit properly with the cable and mating products.
- Prepare the Cable for Connection
Position the cable in its final assembled location, ensuring enough slack for elbow removal. For concentric neutral cable, unwind the neutral wires. Cut the cable 1-3/4 inches (45mm) from the centerline of the mating product. Clean the outer jacket of the cable for a distance of 24 inches (610mm). Follow specific cable preparation instructions (e.g., for jacketed, non-jacketed, Unishield, or lead sheath cable) as detailed in the product documentation, removing the outer jacket and preparing the cable shield as shown in diagrams.
- Prepare Cable Insulation and Install Cable Adapter
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6mm) back. Thoroughly clean the cable insulation, working towards the semi-con shield. Lubricate the cleaned cable insulation. Install the cable adapter, small end first, until it is flush with the edge of the tape marker. Remove any protruding cable insulation by cutting it even with the end of the cable adapter, ensuring not to nick the adapter or conductor. The exposed conductor length must be 4-3/8 to 4-3/4 inches (111-121mm).
- Install and Crimp the Compression Lug
For copper conductors, fully insert the conductor into the compression lug. For aluminum conductors, wire brush the conductor immediately before fully inserting it into the lug. Measure the 'Check Dimension' before crimping; it must be less than 7 inches (178mm). Crimp the compression lug according to the instructions supplied with the lug. After crimping, wipe all excess inhibitor from the lug and cable adapter surface. The distance from the end of the compression lug to the cable adapter must be 6-7/8 to 7-5/8 inches (175-194mm).
- Install the Elbow Connector
Lubricate the cable adapter and the inside of the elbow cable entrance thoroughly. Install the elbow onto the cable adapter, pushing until it cannot advance further. Verify that the cable adapter remains flush with the tape marker; reposition the cable adapter if necessary. Once the elbow is fully seated, remove the tape marker.
- Connect Elbow to Mating Apparatus
WARNING: Do not connect or disconnect mating products while energized. Do not energize while disconnected. Remove any protective caps from both the elbow and the mating part. If the mating part is not equipped with a stud, hand tighten the threaded stud (supplied with the elbow) into the mating part. Clean and lubricate both the elbow and the mating part with the supplied lubricant, ensuring surfaces remain clean. Push the elbow onto the mating part, aligning the hole in the compression lug with the stud on the mating part.
- Connect Opposite End Mating Part (if applicable)
Clean and lubricate the mating part intended for the opposite end of the elbow. Insert this mating part into the elbow. Engage the threads and hand tighten. Torque the mating part according to the specific instructions provided with that mating part.
- Install Insulating Plug and Cap (if applicable)
If an insulating plug is used as a mating part, clean and lubricate the inner surface of the voltage detection cap. Place the cap onto the elbow and push down firmly until it snaps into place.
- Ground Cable Shield and Waterproof Jacket
Insert one end of a wire (with ampacity at least equivalent to No. 14 AWG Copper) through the grounding eye and twist to form a small loop, taking care not to damage the eye. Connect this wire to ground using a suitable connector. The cable shield must be grounded; follow instructions supplied with a grounding device, or use an alternate method. It is also recommended to waterproof the cable jacket at this point to prevent moisture ingress.
- Perform Voltage Test
CAUTION: When constructing 600A L-Kits, tighten each component to specified torque. To test for voltage, remove the test point cap with a hotstick, peeling it off at an angle. WARNING: The voltage test point is a capacitance device, not directly connected to the conductor. Do not use conventional voltage measuring equipment. Use a suitable sensing device designed for capacitive test points. Contamination or incorrect equipment can give a false 'no voltage' indication. Treat the elbow as energized until 'no voltage' is confirmed by other means. After testing, clean and lubricate the cap's inner surface and replace it.
