How to Use Conduit Terminal
Connection
1) Loosen the set screw and remove the terminal block cover
from the terminal block.
2) Loosen the terminal screws on the terminal block, insert the
core of the lead wire or crimped terminal
into the terminal, and attach securely with
the terminal screws.
In addition, when using the DC mode type
with a surge voltage suppressor (polar: S
and Z types), connect wires to terminal 1
and 2 corresponding to the polarity (+ or –)
as shown on the figure on the right.
3) Secure the cord by fastening the ground nut.
DIN (EN175301-803) Terminal
Y type DIN terminal corresponds to the DIN connector with
terminal pitch 10 mm, which complies with EN175301-803B.
Since the terminal pitch is different from the D type DIN
connector, these two types are not interchangeable.

In case of connecting wires, select cabtire cords carefully becau-
se if those out of the specified range (ø4.5 to ø7) are used, it will
not be able to satisfy IP65 (enclosure).
Tighten the ground nut and set screw within the specified range
of torque.

Caution
• Please connect correctly the lead wires to + (positive) and –
(negative) indications on the connector. (For non-polar type, the
lead wires can be connected to either one.)
• When the valve with mis-wiring protection diode is used, the
voltage will drop by approx. 1 V. Therefore, pay attention to the
allowable voltage fluctuation (For details, refer to the solenoid
specification of each type of valve).
• Solenoids, whose lead wires have been pre-wired: + (positive)
side red and – (negative) side black.

Especially when a resistor and a switching element are used
in parallel or C-R device (surge voltage suppressor) is used
for the protection of the switching device, note that leakage
voltage will be increased by passing leakage voltage through
the resistor and C-R device. Therefore, suppressor residual
leakage voltage should be as follows.
3% or less of the rated voltage
8% or less of the rated voltage
Leakage Voltage
Caution
 If a valve is continuously energized for long periods of time,
the rise in temperature due to heat-up of the coil assembly
may cause a decline in solenoid valve performance, reduce
service life, or have adverse effects on peripheral equipment.
If the valve is continuously energized for a long time, or the
total energizing time per day becomes longer than the non-
energizing time, use a valve with power saving circuit.
Also, it is possible to reduce the energizing time by using a
N.O. (normally open) valve.
 When the valve is mounted onto a control panel, take
measures against radiation in order to keep the valve
temperature within the specified range.
