Back page 3
When shutting off the DC power supply using an emergency
circuit breaker, the valve may operate incorrectly due to surge
voltage generated by other electric parts (e.g., the solenoid).
To ensure that surge does not affect the valve, take anti-surge
measures (diode for surge protection, etc.) or use a valve with
diode to prevent reverse current. (Contact SMC for model
numbers.)
Not necessary if ordering the lead wire pre-connected model.
Strip 3.2 to 3.7 mm at the end of the lead wires, insert the
ends of the core wires evenly into the sockets, and then crimp
with a crimping tool. When this is done, take care that the cov-
erings of the lead wires do not enter the core wire crimping
area.
Crimping tool part no. DXT170-75-1

wires
Attaching
Insert the sockets into the square holes of the connector ( ,
indication), and continue to push the sockets all the way in un-
til they lock by hooking into the seats in the connector. (When
they are pushed in, their hooks open and they are locked au-
tomatically.) Then, confirm that they are locked by pulling
lightly on the lead wires.
Detaching
To detach a socket from a connector, pull out the lead wire
while pressing the socket’s hook with a stick having a thin tip
(approx. 1 mm). If the socket will be used again, first spread
the hook outward.
with a new type for maintenance or other
reasons, a “conversion connector assem-
bly” is necessary to convert the connector
from 3 terminals to 2 terminals and must be
ordered separately. (When ordering, refer to
the below part nos.)
For pilot valves, there is no compatibility between the conven-
tional type and new type. When replacing a pilot valve, be
sure to confirm whether it is the new type or the conventional
type.
