VCP-W circuit breaker installation and removal using a lift pan For installation and removal of VCP-W circuit breaker into a medium voltage switchgear using a breaker lift pan in conjunction with a breaker lifting device and a set short rails, reference the following instructions. A. Installation: Figure 13. Breaker Wheel Interlock. 1. Follow steps outlined in Section 2, A-1 to lift the breaker from its shipping pallet using breaker lifter and breaker lifting yoke. At this time, the circuit breaker is hanging on the lifter hook (Figure 9). 2. Position the lifter behind the lift pan such that circuit breaker is positioned above the lift pan. 3. Carefully lower the breaker on to the lift pan making sure all four breaker wheels are seated on the lift pan rails. Once the breaker is fully lowered on to the lift pan and seated, disengage the lifter hook from the lift yoke, and remove the lifting yoke from the breaker. Now pull the breaker towards the front until the breaker front panel is rested against the two rubber stops (Figure 12) on the lift pan. As the breaker is being pulled towards the rubber stops, interlock bars on the lift pan will engage breaker wheels shaft (Figure 13) to keep the breaker from sliding off the lift pan. The interlock bars are further illustrated in the lift pan drawing (Figure 34) and labeled as Clamp seen in the side view. WARNING FAILURE TO ENGAGE THE INTERLOCK BARS ENTIRELY MAY LEAD TO MOVEMENT OF THE CIRCUIT BREAKER WITHIN THE LIFT PAN. THIS CAN RESULT IN DEATH, SERIOUS PERSONAL INJURY OR PROPERTY DAMAGE. 4. Engage the lift pan hooks (Figure 23) to the lifter horizontal lifting bar (Figure 24) by lowering the lift, pushing the lifter slightly forward, and then raising the lift. When properly engaged, the lift pan can be raised/lowered to raise/lower the breaker (Figure 14). 5. Engage the short rails (Figures 3A, 21 and 22) into the breaker compartment. 6. Move the breaker lifter with lift pan and breaker, and carefully position in front of the circuit breaker compartment (Figure 14). 7. Raise/lower the lift to align the two holes on the lift pan to rail pins. (Figures 25A, 25B and 25C). Two site holes (Figure 23) are provided on the lift pan for visual verification of final alignment of the lift pan with the short rails, when installing breaker in the upper compartment. Once aligned, push the lifter and lift pan to fully engage the rail pins. When fully engaged, a spring-loaded bracket on each rail will lock the rails to the lift pan. Verify that the lift pan rails are now aligned with the compartment rails (Figures 15 and 16). Figure 14. Lift Pan Being Raised. WARNING FAILURE TO ENGAGE THE SPRING-LOADED BRACKETS SEEN IN FIGURES 15 AND 16, MAY LEAD TO UNEVEN RAIL ALIGNMENT AND/OR MOVEMENT OF THE LIFT PAN.

Now lock the lift truck wheels by pressing wheel lock paddle (Figure 17) by foot. 8. Disengage lift pan wheel locking pins from both wheels (Figure 29B), and then unwind the strap (Figures 26A and 26B) from lift pan winch assembly by simply pulling it. eave enough slack. Make sure the strap is positioned above the spring rod and not below it (Figure 26B) before proceeding to the next step. 9. Lift the breaker pull-handle upward (Figure 27A) and slide the strap metal piece horizontally underneath the handle (Figure 27A and 27B), then rotate it 90 degrees downward, and push it straight down. When properly inserted, this metal piece will lock in with the breaker cross piece just below the handle and will maintain breaker pull-handle in the raised position, thus releasing breaker and cell interlock to allow breaker to be withdrawn from its disconnected position. Now pull the strap (Figure 28) just to be sure that the metal piece is engaged correctly as shown before proceeding to the next step. 10. Now rotate the lift pan wheel (Figure 29A) clockwise. There are two wheels, one on the left and one on the right. Either wheel can be used. As the wheel is rotated clockwise (Figure 30), it will wind the strap and pull the breaker from its compartment. Continue to pull the breaker onto the lift pan until the breaker front panel is rested against the two rubber stops (Figure 12) on the lift pan. As the breaker is being pulled towards the rubber stops, interlock bars on the lift pan will engage breaker wheels shaft (Figure 13) to keep the breaker from sliding off the lift pan.
