For AC
• There is no "S" type because the generation of surge voltage is
prevented by a rectifier.
• Surge voltage suppressor of varistor has residual voltage
corresponding to the protective element and rated voltage;
therefore, protect the controller side from the surge. The residual
voltage of the diode is approximately 1 V.

How to Use DIN Terminal
Caution
● Connection
1. Loosen the holding screw (1) and pull the connector out of the
solenoid valve terminal block.
2. After removing the holding screw (1), insert a flat head screwdriver,
etc. into the notch (2) on the bottom of the terminal block and pry
it open, separating the terminal block (2) and the housing.
3. Loosen the terminal screws (slotted screws) (4) on the terminal
block (2), insert the cores of the lead wires into the terminals
according to the connection method, and fasten them securely with
the terminal screws (4).
4. Secure the cord by fastening the ground nut (5).
∗When making connections, take note that using other than the
supported size (ø3.5 to ø7) heavy duty cord will not satisfy IP65
(enclosure) standards.
Also, be sure to tighten the ground nut (5) and holding screw (1)
within their specified torque ranges.
● Changing the entry direction
After separating the terminal block (2) and housing (3), the cord entry
can be changed by attaching the housing (3) in the desired direction
(4 directions at 90° intervals).
∗When equipped with a light, be careful not to damage the light
with the cord's lead wires.
● Precautions
Plug in and pull out the connector vertically without tilting to one side.
● Compatible cable
