5 Product information Introduction Eaton s Cooper Power series Cleer loadbreak connector system is a 600 A loadbreak device available in ratings for operation on 15, 25, and 35 kv class systems. It is used to provide a visible break and visible ground on 600 A network and distribution systems without having to remove 600 A terminations and move heavy cable. The Cleer loadbreak connector system is fully shielded, submersible, and meets the applicable requirements of IEEE Std standard Separable Insulated Connector Systems. The 600 A Cleer loadbreak bushing insert is used with standard 600 A, 35 kv bushing extenders to adapt 600 A, 35 kv bushings manufactured to IEEE Std standard to 600 A Cleer loadbreak interfaces for switchgear applications. Acceptance and initial inspection Each loadbreak bushing insert is completely inspected and tested at the factory. It is in good condition when accepted by the carrier for shipment. Upon receipt of a loadbreak bushing insert, inspect it thoroughly for damage and loss of parts incurred during shipment. If damage or loss is discovered, file a claim with the carrier immediately. Handling and storage If the loadbreak bushing insert is to be stored for an appreciable time before installation, provide a clean, dry storage area. Locate the insert so as to minimize the possibility of physical damage. Quality standards ISO 9001-Certified Quality Management System Read this manual first Read and understand the contents of this manual and follow all locally approved procedures and safety practices before installing or operating this equipment. Additional information These instructions cannot cover all details or variations in the equipment, procedures, or process described nor provide directions for meeting every possible contingency during installation, operation, or maintenance. When additional information is desired to satisfy a problem not covered sufficiently for the user s purpose, please contact your Eaton representative. Installation Instructions MN650016EN July

DRAIN WIRE Drain Wire to TAB OF MATING Mating Component COMPONENT DRAIN WIRE TO Drain MATING Wire to Mating COMPONENT Component Operating instructions High Voltage. Cleer 600 A loadbreak bushings from Cooper Power Systems should only be mated with other Cleer 600 A loadbreak products. Do not attempt to mate 200 A loadbreak or 600 A deadbreak products to Cleer 600 A loadbreak bushings. Failure to comply could lead to a fault that may result in death or serious injury. High Voltage. Do not close or pull the Cleer connector slowly onto or off of the bushings during a loadmake or loadbreak operation. Failure to comply could tease the contacts, leading to excessive arcing causing a fault that may result in death or serious injury. High Voltage. The Cleer 600 A loadbreak connector system is not designed to be switched under water. When operating the Cleer 600 A loadbreak connector system where moisture is present, such as during a rainstorm, take steps to ensure the connector interfaces stay dry. Failure to comply could lead to a fault that may result in death or serious injury. Do not connect two different phases of a multiple-phase system. Before closing a single-phase loop, make certain both ends of the loop are the same phase. DRAIN Drain WIRE Wire Tab TAB Drain DRAIN Wire WIRE to System TO SYSTEM Ground GROUND Figure 8. Extenders and inserts installed on both bushings Step 6 Clean and lubricate interface of loadbreak bushing inserts and loadbreak C connector. Attach loadbreak C connector drain wire to system ground bus with sufficient slack for operation. Always orient the loadbreak C connector such that the drain wire is attached to the bottom of the loadbreak C connector. Loadmake operation High Voltage. The operator should always use personal protective equipment (insulated gloves, clampstick, and eye protection) whenever operating the connector. The operator should always be in the best possible operating position, providing firm footing and enabling a secure grasp of the clampstick positioned to the side of one s torso, while maintaining positive control of the connector before, during, and immediately after operation. If there is any question regarding the operator s operating position, de-energize the connector before operation. The operator should not be looking directly at the connector during the moment of circuit interruption or connection. Failure to comply could result in death or serious injury. Area must be clear of obstructions or contaminations that would interfere with the operation of the loadbreak C connector. Securely fasten a clampstick to the operating eye of the connector. Place the loadbreak C connector over the bushings, inserting both white arc followers of the probes into both bushings approximately 1-1/2" (38 mm). This will align and stabilize the connector. 4 Installation Instructions MN650016EN July 2018

9 High Voltage. Verify that BOTH arc followers are approximately 1-1/2" into the bushings. Failure to comply could lead to a fault that may result in death or serious injury. Turn your back to the bushings and grasp the clampstick securely and obtain good footing. Slam the loadbreak C connector onto the bushing with one firm, quick, and continuous motion. Turn around and apply a force to the clampstick to push the loadbreak C connector onto the bushing. The yellow latch indicator rings on the bushings should be visible in the loadbreak C connector cuff windows at this point. See Figure 9. Yellow latch indicator rings are visible Drain DRAIN Wire WIRE to TO SYSTEM System Ground GROUND Figure 9. Yellow latch indicator rings are visible To check that the loadbreak C connector is properly latched, apply a gentle pull force to the clampstick. When latched properly, the loadbreak C connector will slide back off of the bushing about 1/4" (5 mm) and stop. The yellow latch indicator rings on the bushings should not be visible at this point. See Figure 10. Fault close It is not recommended that operations be made on known faults. If a fault is experienced, the connector and bushings must be replaced. Loadbreak operation Area must be clear of obstructions or contaminants that would interfere with this operation. Secure connector operating eye firmly onto clampstick and lock. Thrust clampstick forward until the loadbreak C connector moves approximately 1/4" (5 mm) further onto the bushings. This action will break any surface friction between outer surfaces of bushings and inner surfaces of loadbreak C connector interfaces. The yellow latch indicator rings on the bushings should now be visible in the cuff windows of the loadbreak C connector. Looking away from the loadbreak C connector, pull the clampstick and withdraw the loadbreak C connector from bushings with a fast, firm, straight motion. The minimum amount of travel of loadbreak C connector to break load is 9" (230 mm). Using the clampstick, move the loadbreak C connector away from the bushings and place the metallic portion of one of the probes directly onto a ground plane. This will discharge any capacitive charge that may still be on the probes. Alternatively, the loadbreak C connecter can be mated directly with the Cleer standoff bushing to discharge any capacitive charge that may still be on the probe. High Voltage. If the fiberglass contact tube of one or both loadbreak bushing(s) extends forward, the unit MUST be replaced. Failure to comply could cause thermal runaway failure or failure to successfully faultclose; this may result in serious personal injury. Place an insulated protective cap with ground wire attached to system ground on the exposed energized bushings using clampstick.
