Removing Terminal Blocks - Honeywell Sylk SI06042 Product Data

IMPORTANT
To prevent bending or breaking the alignment pins
on longer terminal blocks, insert the screwdriver at
several points to evenly and gradually lift up the
terminal block.
Insert the screwdriver blade no more than 1/8 in.
(3 mm) to prevent damage to the terminal block
alignment pins on the device circuit board.
SHORT TERMINAL BLOCK
Fig. 10. Removing Terminal Blocks.
1. Use a thin-bladed screwdriver to evenly raise the ter-
minal block from its alignment pins:
a. For short terminal blocks (1 to 5 terminals),
insert screwdriver blade in the center of the ter-
minal block and use a back and forth twisting
motion to gently raise the terminal block from its
alignment pins 1/4 in. (6.35 mm).
b. For long terminal blocks (6 or more terminals),
insert screwdriver blade on one side of the termi-
nal block and gently rotate the blade 1/4 turn.

Then, move to the other side of the terminal
block and do the same. Repeat until the terminal
block is evenly raised 1/4 in. (6.35 mm) from its
alignment pins.
2. Once the terminal block is raised 1/4 in. (6.35 mm)
from its alignment pins, grasp the terminal block at
its center (for long terminal blocks grasp it at each
end) and pull it straight up.
