4.9 TERMINAL BLOCK WIRE INSTALLATION AND
REMOVAL
Proceed with the following steps and associated pic-
tures to install or remove terminal block wiring.
Step 1: Pictured above are two tension clamp terminal
blocks. There is a large one and small one, but the
operation is the same for both. A small tool, such as a
screwdriver, will be pushed into the square hole next to
the wire hole and a wire will be inserted into the larger
circular hole on the outer edge.
Step 2: Begin by inserting a small, flathead screwdriver
into the square (tool) hole with the flat surface of the
screwdriver against the back wall of the hole. With a lit-
tle bit of force, push the screwdriver in on a slight angle
toward the center of the clamp. Be sure to slide it in until
it clicks. You will then see the clamp open in the wire
hole.
Step 3: Once the screwdriver is in place, obtain a
stripped wire (strip about 1/4 of an inch) and insert it into
the larger circular wire hole. Push the wire in until it can
go no further.
Step 4: Next, while holding the wire in place, pull the
screwdriver out. The wire will now be held in securely.
Finally, pull on the wire to insure that it is correctly
inserted into the clamp.
Step 5: There are three additional pieces to these termi-
nal blocks. The plug and lock can only be used with the
large terminal block, while the yellow shorting strap can
be used for both.
