a. Strip 3/16 in. (0.187 in. or 0.47 cm.) of insulation from the end of the wire.
b. Place the receptacle contact spring into the jaws of the proper crimping tool.
c. 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.)
d. 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. Always 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.
e. 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.

2.4.4. Base Wiring for Series or Parallel Connected Coils

PN-150BE relay coils can be either series or parallel connected by externally wiring the
mounting base (see Figure 2-3).

2.5. RELAY INSERTION

Orient the relay to the mounting base with the push rod to the left-hand side; 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.
