8. Verify that the wire markers are clearly visible and not damaged so that they are wired easily and efficiently.
9. Be careful that that the wires are not pinched or damaged while installing the secondary disconnect blocks.

Tools required: wire stripper, wire cutter, and a Philips-head screw driver, M6 wrench
As mentioned above, the secondary disconnect blocks are available with all blocks installed. In this case, the wires
on the blocks are routed through one side of the breaker and then on to the front. The wires on the front are left
loose for tease of landing them to the EntelliGuard ACB breaker secondary disconnects.
When the secondary disconnect blocks are installed at the customer’s site, the wires would not have been already
routed. The wires should not be routed from the outside of the metal structure as it might interfere with the motion
of the kit during the racking into the compartment. Also, it should be kept in mind that the wires are securely fixed
on the inside metal frame of the Retrofill kit with sticky pads and tie-wraps.
Check that wire routing does not exert pressure on the bullets because this can bend the connection points and
effects biasing and contact pressure. By using tie-wraps and sticky-pads, wire routing can eliminate sagging of the
wire harness and undue pressure on secondary bullets.
Once the above mentioned steps are completed, landing the wires to the points on the EntelliGuard ACB
secondaries can begin.
