INSTALLATION

1. Remove the two 1/4-20 x 5/8" screws and

lockwashers from the outer handle mechanism.

Place each screw and lockwasher though the pivot

bracket assembly Thread the retaining washers

enclosed in the parts kit onto the 1/4-20 x 5/8"

screws. See Figure 1-1.

2. Connect the actuator link from the outer handle

mechanism on the pivot bracket assembly Mount

the pivot bracket assembly to the enclosure and

outer handle mechanism by securing the mounting

hardware. Attach the E-Ring supplied in the parts kit

to the actuator link. See Figure 1-1.

3. Drill and tap the mounting holes for the circuit

breaker. See breaker frame instruction leaflet for the

drilling pattern.

Note: Be certain that there is a 5 inch minimum

clearance between the load end of the breaker and

wall of the enclosure for the flex shaft.

4. Mount breaker's Line end to enclosure using the

mounting hardware supplied in the hardware kit.

5. Attach the base plate and mounting hardware to the

load end of the circuit breaker per the following

breaker frames:

LD: Attach the base plate and Load end of the breaker

to enclosure using the 1/4-20x4.75" screws and lock-

washers enclosed. See Figure 1-2 for illustration.

M: Attach the Load end of the breaker to the enclosure

using hardware frame parts kit. Attach the base plate to

the Load end cover on the (M) type breaker. The load

end cover screws are replaced with the (2) 10-32x2"

screws and lockwashers enclosed. (Not shown in Figure

1-2).

MDL: Attach the load end of the breaker to the enclo-

sure using hardware from the hardware kit. Attach the

base plate to the load end cover of the breaker. The

load end cover screws are replaced with the (2) #8-

32x2.25" screws, #8 lockwashers, and mounting

sleeves enclosed. See Figure 1-2 for illustration.

ND: Attach the Load end of the breaker to the enclosure

using hardware from the hardware kit. Attach the base

plate to the circuit breaker using the 1/4-2Ox3.5" screws

and 1/4" lockwashers enclosed in the parts kit at the

load end of the breaker after removing the (2) load

cover screws located between the trip unit and the two

load end mounting holes. See Figure 1-2 for illustration.

Effective 2/01

RD: Attach the Load end of the breaker to the enclosure

using the hardware from the hardware kit. Attach the

base plate to the circuit breaker using the 1/4- 20x3.75"

screws and 1/4" lockwashers enclosed in the parts kit at

the load end of the breaker. See Figure 1-2 for illustra-

tion.

Note: Prior to Dec. 1994: The Breaker mounting

hardware for Line end and Load end mounting

(except LD) were in the appropriate breaker frame

mounting hardware kit. The mounting hardware is

now included in the hardware parts enclosed.

6. Place the outer handle mechanism in the full ON

position and the circuit breaker in the ON position.

You must Release Cover interlock to move handle

to ON position. Place the handle extension assem-

bly onto the breaker handle and secure as shown

on Figure 1-2.

Note: LD and MD use clamp type assembly: ND and

RD use a through bolt for handle attachment from

the hardware kit.

7. Locate bulk head nuts of the flexible shaft over the

groove of the base plate and tighten.

8. Actuate the outer handle positions (ON, OFF,

RESET). If minor adjustments are necessary, refer

to the following adjustment checklist and Figure 1-2.

Install appropriate door hardware (supplied); as

referenced on Figure 1-3.

ADJUSTMENT CHECKLIST

Situation:

Breaker turns ON and OFF, but will not RESET when

tripped.

Adjustment:

Loosen the 1/4-28 adjusting nut that is closest to the

black cap and turn towards the cap about 1.5-2 turns.

Retighten the adjusting nut that is on the end of the

shaft to the handle extension and inner adjusting nut.

Recheck for the ON, OFF and RESET position. If not

successful, repeat procedure. If still not successful, and

the adjusting nut is bottomed out onto the shaft, loosen

the bulk head nuts, and shift the cable towards the Load

end of the breaker. Re-tighten the bulk head nuts.

Recheck for the ON, OFF and RESET position. If not

successful, repeat the beginning steps.
