THE BREAKERS AND THEIR ENCLOSURES ARE SIGNED WITH SEVERAL BUILT-IN INTERLOCKS AND SAFETY FEATURES INTENDED TO PROVIDE SAFE AND PROPER OPERATING SEQUENCES. TO PROVIDE MAXIMUM PROTECTION FOR PERSONNEL ASSOCIATED WITH THE INSTALLATION, OPERATION, AND MAINTENANCE OF THESE BREAKERS, THE FOLLOWING PRACTICES MUST BE FOLLOWED. FAILURE TO FOLLOW THESE PRACTICES MAY RESULT IN DEATH, PERSONAL INJURY, OR PROPERTY DAMAGE. Safety Precautions Periodic tests if this device is required (see Step 12 Testing the Breaker for test procedures). Only qualified persons, as defined in the National Electric Code, who are familiar with the installation and maintenance of power circuit breakers and their associated switchgear assemblies should perform any work associated with these breakers. Completely read and understand all instructions before attempting any installation, operation, maintenance, or modification of these breakers. Always turn off and lock out the power source feeding the breaker prior to attempting any installation, maintenance, or modification of the breaker. Do not use the circuit breaker as the sole means for isolating a high voltage circuit. Follow all lockout and tagging rules of the National Electric Code and all other applicable codes, regulations, and work rules. Do not work on a closed breaker or a breaker with the closing springs charged. Trip (open) the breaker and be sure the stored energy springs are discharged before performing any work. The breaker may trip open or the charging springs may discharge, causing crushing or cutting injuries. For drawout breakers, trip (open), and then remove the breaker to a well-lit work area before beginning work. Do not perform any maintenance: including breaker charging, closing, tripping, or any other function which could cause significant movement of the breaker while it is on the extension rails. Doing so may cause the breaker to slip from the rails and fall, potentially causing severe personal injury to those in the vicinity. Do not leave the breaker in an intermediate position in the switchgear cell. Always leave it in the connected, disconnected, or (optional) test position. Failure to do so could lead to improper positioning of the breaker and flashover, causing death, serious personal injury, and / or property damage. Do not defeat any safety interlock. Such interlocks are intended to protect personnel and equipment from damage due to flashover and exposed contacts. Defeating an interlock could lead to death, severe personal injury, and / or property damage 4 eaton corporation www.eaton.com

Secure the Finger-Safe Covers to the CPT using the (4).098-28.375" screws supplied with the CPT Kit. Torque the screws to 8-10 in./lbs. NOTE: The power convention of Circuit Breakers is normally Top to Bottom, meaning the top Stud Assemblies (Breaker Stabs) are on the Line Side of the Breaker and the bottom Stud Assemblies are on the Load Side. The HV Wires from the CPT MUST BE ATTACHED to the Line Side of the Breaker. If it is determined that the power EATON CORPORATION www.eaton.com 21

Digitrip Retrofit System for ITE K-3000, flow for the Breaker application is opposite the normal convention, the HV Wires must be attached to the bottom Stud Assemblies. In the case of the Line Side being the bottom Stud Assemblies, the bolts that secure the bottom Stud Assemblies to the Pole Units can be used for HV Wire attachment. I. Install the appropriate CPT Voltage Label in a clearly visible location on the Outer / Inner Front Breaker Cover Assembly. WARNING WARNING NOTE: The Line Side HV Wires are longer than necessary and are cut during the following steps. Before cutting the wires, be sure that sufficient length is left so that the HV Wire Fuses are accessible and that the connections can be made to the correct Stud Assemblies. F. Route the HV Line Side Wires over the top, rear Breaker Channel towards the Phase 1 and 2 or the Phase 2 and 3 top Stud Assemblies.

Digitrip Retrofit System for ITE K-3000, Instructional Leaflet IL 33-858-4A STEP 12: TESTING THE BREAKER A. Measure the force necessary to trip the Breaker at where the Trip Finger impacts the DTA Adjusting Disk. The force necessary to trip the Breaker MUST NOT EXCEED 3 lbs. Fig. 69 External Harness Secured to the Trip Unit / Aux. CT Module Assembly Mounting Bracket. G. Install the Outer / Inner Front Cover Assembly on the Breaker using the seven (7) original screws removed in Step 2-B. B. The Retrofit must be tested using primary injection. Refer to Section 8 of the Instructions for the Application of Digitrip RMS Retrofit Kits on Power Circuit Breakers (Publication AD 33-855), supplied with the Retrofit Kit, for detailed testing procedures and specifications. For test information specific to the Trip Unit, refer to the IL publication supplied with the Retrofit Kit (see the Pick List for the IL number). C. While Section 8 of the Instructions for the Application of Digitrip RMS Retrofit Kits on Power Circuit Breakers provides the information necessary for testing the Breaker, please keep the following notes in mind when reviewing other sections of the publication. CAUTION: WHEN ALL TESTING IS COMPLETE, THE TRIP UNIT MUST BE RESET. FAILURE TO DO SO MAY CAUSE THE BATTERY IN THE RATING PLUG TO RUN DOWN. NOTES: 1. For All Kits Other Than 510 Basic: If testing the Breaker with Short Delay or Ground Fault functions, be sure to either plug in the Cell Harness Assembly or use the Zone Interlock Shorting Plug. Failure to do so may result in shorter than expected trip times. 2. For 810 and 910 Kits Only: Without any power applied to the system (neither the 120 volt power supply nor the Aux. Power Module connected), plug the External Harness into the Cell Harness and check the impedance between COM 1 and COM 2. The impedance should be EATON CORPORATION www.eaton.com 31

Digitrip Retrofit System for ITE K-3000, between one (1) and three (3) ohms. If the impedance is not within this range, trace the wiring and examine each connection to assure its integrity. Confirm that the PowerNet communication wiring is correct by following the procedures detailed in Section 7.4 of the Instructions for the Application of Digitrip RMS Retrofit Kits on Power Circuit Breakers. Note that for 810 and 910 Kits, the impedance between COM 1 and COM 2 should be between one (1) and three (3) ohms. STEP 13: MOUNTING THE CELL HARNESS A. The Cell Harness is to be mounted in the Breaker Cell. The connector end is to be mounted on the right side of the Cell, in a location suitable for connection with the External Harness. The Terminal Blocks can be mounted anywhere space is available in the Cell as long as connection to the External Harness can be made. B. Route the Cell Harness wiring to keep it away from any moving parts within the Cell Housing. When testing is complete, disconnect the External Harness from the Cell Harness. Final External Harness connection will be performed later in the Retrofit Process. 32 EATON CORPORATION www.eaton.com

Digitrip Retrofit System for ITE K-3000, Instructional Leaflet IL 33-858-4A STEP 14: INSTALLING THE RETROFITTED BREAKER IN THE CELL WARNING DO NOT LEAVE THE BREAKER IN AN INTERME- DIATE POSITION IN THE SWITCHGEAR CELL. ALWAYS LEAVE IT IN THE CONNECTED, DIS- CONNECTED, OR (OPTIONAL) TEST POSITION. FAILURE TO DO SO COULD LEAD TO IM- PROPER POSITIONING OF THE BREAKER AND FLASHOVER, CAUSING DEATH, SERIOUS PERSONAL INJURY, AND / OR PROPERTY DAMAGE. NOTE: It is the responsibility of the Retrofitter to insure proper Breaker / Cell fit. When racking the Breaker into the Connected position, the Retrofitter MUST FOLLOW BOTH the manufacturer s instructions and the customer s safety standards and procedures for racking a Breaker into the Connected position. A. With the Breaker in the Open position and the springs discharged, slowly rack the Breaker into the Connected position, making sure there is no interference or binding. The Breaker should rack smoothly and without mechanical interference between any Breaker and Cell parts. The Retrofitter will feel some resistance when the primary fingers connect onto the stabs of the Cell. This is normal. However, if any unusual resistance is detected that could be abnormal interference between the Breaker and Cell parts, stop immediately and move the Breaker out of the Connected position. Examine what is causing the interference and correct the situation. EATON CORPORATION www.eaton.com 33
