Step 1: General Breaker Preparation
Before attempting to remove the Breaker, or
perform any Retrofit operation, be sure to read
and understand the Safety Precautions section of
this manual. In addition, be sure to read and
understand the
Instructions for the Application of
Digitrip RMS Retrofit Kits on Power Circuit
Breakers
(Retrofit Application Data - Publication
AD-33-855), supplied with the Digitrip RMS/R
Retrofit Kit.
DO NOT ATTEMPT TO INSTALL OR PERFORM
MAINTENANCE ON EQUIPMENT WHILE IT IS
ENERGIZED. SEVERE PERSONAL INJURY OR
DEATH CAN RESULT FROM CONTACT WITH
ENERGIZED EQUIPMENT. VERIFY THAT NO
VOLTAGE IS PRESENT BEFORE PROCEEDING.
A. Trip the Breaker and remove it from the Cell.
Move the Breaker to a clean, well-lit work
bench.
NOTE: It is the responsibility of the Retrofitter
to insure that the Breaker and all original
components are in good condition. Visually
inspect all Breaker components for signs of
damage or wear. If any signs of damage or
wear are detected for components
not included
in the Retrofit kit, secure the necessary
replacement parts
before
beginning the
Retrofit process.
The force necessary to trip the Breaker must
not exceed 3 lbs.
To begin the Retrofit process, refer to the
components list at the rear of this manual. Lay out
the components and hardware according to the
steps outlined. The parts bags are labeled with the
corresponding step number. The components and
hardware will be used to complete each step of
the Retrofit process.
Step 2: Removing the Original Components
Follow the Federal Pacific 100-HF (Canadian)
Instruction Manual, originally supplied with
Breaker, to perform the following procedure.
A. Remove and scrap the original
Electromechanical Trip System, as well as
any associated parts and hardware.
Step 3: Mounting the Sensors
A. Using the .190-32 × .750" long screws, flat
washers, lock washers, and hex nuts provided,
attach each Sensor to the Glass Poly Sensor
Mounting Bar as shown. Note that the screws
must be inserted from the Glass Poly Sensor
Mounting Bar side.
B. Using the .190-32 × .750" screws, flat washers,
lock washers, and hex nuts provided, attach
the Sensor Mounting Clips to each end of the
Glass Poly Sensor Mounting Bar as shown.
When attached correctly, the bottom edge of
the clips are flush with the bottom of the
Sensor Mounting Bar.
NOTE: Before fully tightening the screws, set
the Sensor Assembly in place to insure proper
fit between the Breaker Rear Channels.
