Step 7:
To remove a fixed secondary terminal block, lift up
on the small flexible mounting tab at the top of fixed terminal
block mounting plate, and rotate the terminal block out in the
opposite direction shown in Step 6.
IMPORTANT
KEEP IN MIND THAT TO REMOVE AN ACCESSORY PLUG ON A FIXED
CIRCUIT BREAKER, THE APPROPRIATE FIXED SECONDARY TERMINAL
BLOCK MUST FIRST BE REMOVED. ONCE THE TERMINAL BLOCK IS
REMOVED, THE ACCESSORY CONNECTOR PLUG CAN BE UNPLUGGED
FROM THE BOTTOM OF THE TERMINAL BLOCK. REFER TO FIGURE 4 IN
SECTION 1 FOR ASSISTANCE WITH THE REMOVAL.
Step 8:
Once all terminal blocks are securely mounted, replace
the front cover and secure it in place with the four mounting
screws previously removed in Step 1.
Section 3: Installation and Removal of
Drawout Terminal Blocks
IMPORTANT
KEEP IN MIND THAT THE SECONDARY TERMINAL BLOCKS ASSOCI-
ATED WITH DRAWOUT CIRCUIT BREAKERS ARE MOUNTED ON THE
BREAKER’S DRAWOUT CASSETTE (FIGURE 11). ACCESSORY SECOND-
ARY 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 DIS-
CONNECTED DURING THE LEVERING (RACKING) PROCESS AS THE
SECONDARY PLUG HOUSING ON THE BREAKER ENGAGES OR DIS-
ENGAGES 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 TER-
MINAL BLOCKS. REFER TO FIGURES 3 AND 4 OF SECTION 1 AND THE
ASSOCIATED COPY FOR ASSISTANCE WITH CONNECTING OR DISCON-
NECTING ACCESSORY SECONDARY PLUGS.
