Check that the bullets, on top of the secondary disconnects, are not damaged and that they slide in to the
blocks freely. The bullets are spring-loaded and return to their initial positions when they are released from
being pressed down.
3.
Check for electrical continuity between the bullets on one end and the wire terminations on the other.
Blocks containing faulty bullets should be replaced.

Place the secondary disconnect block on top of the horizontal plate at the rear of the Retrofill EntelliGuard

5.
Align the three holes on the face of the supplied secondary block to the three holes on the plate and secure
the block to the plates using the hardware provided as mentioned above. The screw tightening torque

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 ease 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 tie-wraps.
