General Installation
THE VOLTAGES IN ENERGIZED EQUIPMENT CAN
CAUSE DEATH OR SEVERE PERSONAL INJURY.
BEFORE REMOVING A CIRCUIT BREAKER
INSTALLED IN AN ELECTRICAL SYSTEM, MAKE
SURE THE CIRCUIT BREAKER IS SWITCHED TO
THE
OFF POSITION AND THERE IS NO VOLTAGE
PRESENT WHERE WORK IS TO BE PERFORMED.
SPECIAL ATTENTION SHOULD BE PAID TO
REVERSE FEED APPLICATIONS TO ENSURE NO
VOLTAGE IS PRESENT.
Steps 2-1 through 2-8 and 2-11 through 2-17 are for
general installation and apply to the ASL switch and
the accessory combination. Step 2-9 covers instal-
lation of the accessory combination.

2-1. Switch circuit breaker to OFF position.
Molded case switch trip units are not equipped with
a Push-to-Trip button. For molded case switches,
omit step 2-3.
2-2. Disconnect and remove circuit breaker from
installation and terminal connections.
2-3. Press PUSH-TO-TRIP button to trip operating
mechanism and check handle moves to trip
position with white colored indicator visible in
escutcheon window.
2-4. Remove circuit breaker cover screws and covers.
To install accessory, circuit breaker must be in
tripped position
2-5. For high instantaneous trip-type (catalog suffix K
designation) molded case switches, find
recessed hole in either of the trip unit outer poles
normally intended for intermediate plunger
(Figure 2-4). Push a fine point implement in one
hole to trip the molded case switch.
2-6. Remove interphase barrier between center pole
and pole in which accessory is to be mounted
(Figure 2-2).
2-7. Install replacement interphase barrier (supplied
with kit) in base (Figure 2-2).
For all combinations of accessories, leads from the
inner accessory switch must go to the wiring trough
nearest the line end of the circuit breaker. For a dou-
ble or triple combination, leads from the outer acces-
sory switch must go to the center trough. Pigtail
leads exiting in this manner should be eased through
trough as mounting bracket is inserted into trip unit
retaining slots. Use center trough also for leads exit-
ing the side of the circuit breaker.
2-8. Route wiring to meet installation requirements
(see Figure 2-3).
