Installation/Removal Instructions
for Series NRX Drawout Secondary
Terminal Block Alignment Bracket
WARNING
(1) ONLY QUALIFIED ELECTRICAL PERSONNEL SHOULD BE PERMITTED TO
WORK ON THE EQUIPMENT.
(2) ALWAYS DE-ENERGIZE PRIMARY AND SECONDARY CIRCUITS IF A
CIRCUIT BREAKER CANNOT BE REMOVED TO A SAFE WORK LOCATION.
(3) DRAWOUT CIRCUIT BREAKERS SHOULD BE LEVERED (RACKED) OUT TO
THE DISCONNECT POSITION.
(4) ALL CIRCUIT BREAKERS SHOULD BE SWITCHED TO THE OFF POSITION
AND MECHANISM SPRINGS DISCHARGED. FAILURE
TO FOLLOW THESE
STEPS FOR ALL PROCEDURES
DESCRIBED IN THIS INSTRUCTION LEAFLET
COULD RESULT IN DEATH, BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
THE INSTRUCTIONS CONTAINED IN THIS IL AND ON PRODUCT LABELS
HAVE TO BE FOLLOWED. OBSERVE THE FIVE SAFETY RULES:
– DISCONNECTING
– ENSURE THAT DEVICES CANNOT BE
ACCIDENTALLY RESTARTED
– VERIFY ISOLATION FROM THE SUPPLY
– EARTHING AND SHORT-CIRCUITING
– COVERING OR PROVIDING BARRIERS TO
ADJACENT LIVE PARTS
DISCONNECT THE EQUIPMENT FROM THE SUPPLY. USE ONLY
AUTHORIZED SPARE PARTS IN THE REPAIR OF THE EQUIPMENT. THE
SPECIFIED MAINTENANCE INTERVALS AS WELL AS THE INSTRUCTIONS
FOR REPAIR
AND EXCHANGE MUST BE STRICTLY ADHERED TO PREVENT
INJURY TO PERSONNEL AND DAMAGE TO THE SWITCHBOARD.
Section 1: Removal and Installation
And Removal of Drawout Terminal Block
Alignment Bracket
IMPORTANT
KEEP IN MIND THAT SECONDARY TERMINAL BLOCKS ASSOCIATED
WITH DRAWOUT CIRCUIT BREAKERS ARE DIN RAIL MOUNTED ON
THE BREAKER’S DRAWOUT CASSETTE (FIGURE 11). ACCESSORY
SECONDARY PLUGS PLUG INTO A SECONDARY PLUG HOUSING
MOUNTED ON THE TOP FRONT OF THE CIRCUIT BREAKER (FIGURE 12).
AS SUCH, SECONDARY CONNECTIONS ARE AUTOMATICALLY MADE
OR DISCONNECTED DURING THE LEVERING (RACKING) PROCESS AS
THE SECONDARY PLUG HOUSING ON THE BREAKER ENGAGES OR
DISENGAGES THE SECONDARY TERMINAL BLOCKS MOUNTED ON THE
DRAWOUT CASSETTE. FOR THIS REASON, ACCESSORY SECONDARY
PLUGS DO NOT HAVE TO BE UNPLUGGED TO ADD OR REMOVE
TERMINAL BLOCKS. REFER TO FIGURES 3 AND 4 OF SECTION 1 AND
THE ASSOCIATED COPY FOR ASSISTANCE WITH CONNECTING OR
DISCONNECTING ACCESSORY SECONDARY PLUGS.

Proceed with the following 6 steps:
Step 1: Become familiar with the drawout terminal block
(Figure 1) and the cassette’s DIN rail mounting location.
In addition, a terminal block alignment bracket is bolted in
place to provide for proper alignment and separation of each
individual terminal block during the levering (racking) process.
Two alignment brackets are used with the RF Frame cassette
since two cradles are required to accommodate the additional
terminal blocks. The bracket’s separation teeth ensure this
alignment and separation (Figure 2). Terminal block alignment
brackets must be removed to add or remove terminal blocks.
Brackets are supplied as part of the cassette and also have
etched numerical identifications.
All of these identifications match the identifications on the
breaker’s secondary plug housing to ensure accurate terminal
block placement.

Step 2: Remove the four mounting screws holding the termi-
nal block alignment bracket in place.
Figure 4. Step 2
Step 3: Carefully slide the alignment bracket out from
between any mounted terminal blocks, and discard with its
mounting hardware.
Figure 5. Step 3
Step 4: Carefully put the new terminal block alignment brack-
et into position by sliding it back into the DIN rail mounted
terminal blocks.
Figure 6. Step 4
Step 5: Once the terminal block alignment bracket is in place,
inspect it from the bottom to ensure that the teeth on the
bracket separate each individual terminal block. One installed
terminal block only should be visible between two teeth
when the alignment bracket is properly positioned.
Figure 7. Step 5
Step 6: Secure the terminal block alignment bracket using the
four preassembled screws. Hand tighten the four mounting
screws to complete the installation process.
