WIRING
Do not pinch/damage the wires while installing
the secondary disconnect blocks.

AKD-6 - Secondary Disconnects, Bullets
Wire Secondary Disconnect Assembly-AKR30/30H/50/50H/75/100
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 ease of landing them to the Emax 2
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.
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, 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
Emax 2 ACB secondaries can begin.
Once the above mentioned steps are completed, begin landing the wires to the points on
the secondaries, based on the typical wiring diagrams found in Tables 6,7 and 8.
