3. Partially close the crimping tool jaws against the receptacle contact spring to hold
it in place. (Do not crush the receptacle contact spring barrel at this time.)
4. Insert the stripped end of wire all the way into the receptacle contact spring
barrel. Squeeze the tool handles until crimping is completed and the jaws
release. When using both terminals, it is more convenient to attach the first wire
to the longest terminal. This ensures that a second lead may be attached to the
receptacle contact spring at a later time.
5. Remove the crimped receptacle contact spring from the tool and inspect the
connection. Make certain that the wire is flush with the crimped barrel and that
there are no loose strands of wire.
2.5. Relay Insertion
Orient the relay to the mounting base with the name plate right side up; then plug the
relay into the base. The relay should be pushed firmly against the mounting base while
depressing the latch rod. After the relay is completely seated in the base, release the
latch rod, and pull on the handle to ensure that the relay has locked in place.
