ABB Emax 2 Retrofill, Installation And Maintenance Manual

Page: 24 / 77

After the existing breaker is removed, the compartment modified and secondary wiring
verified, the Retrofill breaker can now be installed in the AKD-10 switchgear, OEM switchgear
or switchboard.
Note : the preferred lifting method is always to use proper ABB lifting (spreader) bar. It will
provide the best chance of installing breakers, especially into the upper compartments,
without damaging the breakers. The WavePro small frame lifting bar had a 3rd lifting hook
at the front and it will not fit on the retrofill breaker. Any time eye bolts (small frame
breakers)
or large diameter holes (large Frame breakers) and generic lifting chains are used,
caution must be
used to keep the chains to no less than 45 degree angle from horizontal to avoid damaging
the breaker side frames)
800A - 2000A Breakers : ABB Lifting Bar #2TSE431929R1000, old GE #0247B8961G002
3200A— 4000A Breakers : ABB Lifting Bar #2TSE431931R1000, old GE #0247B8961G001
5000A Breakers : ABB Lifting Bar #2TSE431932R1000, old GE #0247B8961G003
1. Verify that the breaker is in the DISCONNECTED and OPEN position before mounting
it on the rails. Refer to figure 23.

2. Using the chosen lifting method, raise the breaker to a height slightly above the rails.
3. Pull out the two rails being cautious not to position anyone underneath the suspended
load. Pulling from the middle of the tie bar connecting the two rails and lifting up
slightly will help the rails to slide out more easily.
lt must be ensured that the supply power to the
Shack and Saad compartment is turned off/
compartment is denergized for all the incoming
and outgoingcircuits of the LVS prior to any work
being conducted on it.
During the installation and related work on the
equipment, it must be ensured that the operator
is using the prescribed PPE for the specified
tasks
Ensure only qualified personnel install, operate, service, and maintain all electrical
equipment
