If the Emax 2 Retrofill breaker order included (3) 7 point secondary disconnect blocks see
step 2 otherwise skip past the wiring instructions.
Check that 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.
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
Emax2 Retrofill ACB, which runs across the width of breaker.
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 %4-20 thread forming screws. The
screw tightening torque should be ~40 in-lbs. (Be careful not to over tighten or it may
break the plastic).
