Installing the Trip Unit Mounting Plate
1.
Attach the trip unit mounting plate to the support
bracket, as shown in Figure 14.
a.
The two larger screws at the top attach to
tapped holes in the support bracket.
b.
Pull out the locking lever, as shown, then
insert the small screw through the hole.
c.
Secure the small screw with the flat washer,
lock washer, and nut.
2.
Attach the support bracket and mounting plate to
the breaker frame, as shown in Figure 15. Insert
the two bolts through the existing holes in the
breaker frame and attach to the tapped holes in
the bracket.
3.
Route the four-pin flux shifter connector to the
flux shifter assembly and mate it with the
connector from the flux shifter.
4.
Pass the current sensor leads through the hole
on the lower left side (from the rear) of the
breaker, as shown in Figures 16 and 17.
5
If the trip unit is to be connected to a communi-
cation network, pass the connector through the
rear-frame hole with the CT leads. Otherwise, tie
it to some convenient point on the breaker frame
with wire ties.
6.
If a neutral sensor is to be used in the equipment,
pass the corresponding connector through the
rear-frame hole with the CT leads. Otherwise, tie
it to some convenient point on the breaker frame
with wire ties (with the communication connec-
tor, if also unused).
