WARNING
Standard Warning (General)
WARNING:
READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE.
CRITICAL SAFETY INSTRUCTIONS:
•INSTALLATION SHOULD ONLY BECONDUCTED BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH NEC AND ANY
RELEVANT LOCAL BUILDING CODES.
•RISK OFFIRE OR ELECTRIC SHOCK. FIXTURE INSTALLATION REQUIRES KNOWLEDGE OF FIXTURE'S ELECTRICAL
SYSTEMS. IFNOTQUALIFIED, CONTACT A QUALIFIED ELECTRICIAN.

INSTALLATION
CIRCUIT BREAKER INSTALLATION
Make sure that the equipment is suitable for the installation by comparing nameplate ratings with system requirements.
Inspect the equipment for completeness and check for any damage.
WARNING: MAKE SURE POWER IS TURNED OFF BEFORE STARTING THE
INSTALLATION OR PERFORMING ANY MAINTENANCE.
HAZARD OF ELECTRIC SHOCK, BURN, OR EXPLOSION
1. Before mounting the circuit breaker in an electrical system, make sure there is no voltage present
where work is to be performed.
2. Mount no closer to enclosure metal or live parts than is indicated in drawing.
3. All enclosure closing hardware must be installed.
FAILURE TO FOLLOW THESE INSTRUCTONS WILL RESULT IN DEATH OR SEVERE INJURY.

(See Fig. 1) To mount the circuit breaker perform the following steps:
1. For individual surface mounting, drill and tap mounting bolts holes according to the drilling plan shown in Fig. 2.
For dead- front cover applications, cut out cover to correct escutcheon dimensions refer to Fig. 3 .
2. If circuit breaker includes factory-or field-installed internal accessories, make sure that accessory wiring can be reached when the
circuit breaker is mounted.
3. Position circuit breaker on mounting surface.
4. Install circuit breaker mounting screws and washers. Tighten hardware securely, but do not exceed 13.3 pound-inches (1.5N.m.)

Manual Operation of the circuit breaker is controlled by the circuit breaker handle and the PUSH TO TRIP button. The circuit breaker
has three positions, two of which are shown on the auxiliary cover with raised lettering to indicate ON and OFF. The third position
indicates a TRIP position and is between the ON and OFF positions. (See Fig. 4)
Circuit Breaker Reset
After an automatic or accessory initiated trip, or a manual PUSH TO TRIP operation, the circuit breaker is reset by moving the circuit
breaker handle to the reset position.
Note: In the event of a thermal trip, the circuit breaker cannot be reset until the thermal element in the trip unit cools.
PUSH TO TRIP Button
The PUSH TO TRIP button checks the tripping function and is used to manually exercise the operating mechanism.
Note: Press PUSH TO TRIP button once a year to exercise circuit breaker.
WIRE INSTALLATION
1. Do not allow conductor strands to interfere with threads of wire binding screw.
2. When installing two cables into a lug body make sure cables do not back out during tightening of
the wire binding screw.
