4.2 DIN connector
Connection
1) Loosen the holding screw and pull the connector out of the solenoid valve
terminal block.
2) After removing the holding screw, insert a flat head screwdriver, etc. into the
notch on the bottom of the terminal block and pry it open, separating the
terminal block and the housing.
3) Loosen the 3 slotted screws in the terminal block, insert the cores of the
lead wires into the terminals according to the connection method, and
fasten them securely with the terminal screws.
4) Secure the cord by fastening the ground nut.
When making connections, take note that using sizes of heavy duty cored wire
other than the supported sizes (Ø3.5 to Ø7) will not satisfy IP65 (enclosure)
standards. Also, be sure to tighten the ground nut and holding screw within
their specified torque ranges.
Changing the entry direction
After separating the terminal block and housing, the cord entry can be
changed by attaching the housing in the opposite direction 180°.
*Be careful not to damage the element, etc. with the cord's lead wires.
Precaution
Do not tilt the connector when removing it from the solenoid valve
terminal block.

4.3 Surge Voltage Suppressor (DIN terminal type)
(For DC)
(For AC)
DIN terminal
For AC voltages, "S" specification is
not required because it is already
built into the converter. Do not
include "S" in the part number.
4.4 Leakage voltage
Note that when using a C-R device (surge voltage suppressor) for contact
protection, the voltage leakage may increase due to the current leakage
flowing through the C-R device.
Suppress residual voltage leakage as follows:
DC Coil 3% or less of rated voltage.
AC Coil 8% or less of rated voltage.
Measure to prevent the penetration of the surge voltage
Circuit example
When the DC power supply is
shut off with a emergency stop
circuit, the surge voltage might be
generated from other electrical
products (solenoid coil, etc.),
which
causes
the
valve
to
malfunction. To prevent the
penetration of the surge voltage
to the valve, take a measure for
the
surge
voltage
(surge
suppressing diode, etc) or use a
valve
with
reverse
wiring
preventing diode. (Contact SMC
for order.)

for the surge voltage.
(2) : Valve with reverse wiring
preventing diode.
4.5 Manual override
WARNING
Without an electric signal from the solenoid valve the manual override is used for
switching the main valve.
A Locking type manual override is available as an option (Tool required).

DIN rail removing / mounting
Removing
1) Loosen the clamp screws of both
clamp metal fittings.
2) Lift the
the DIN rail and slide it in the direction
shown.
Mounting
1) Catch the hook of the DIN rail
bracket on the
2) Push side
tighten the clamp screw. The proper
tightening torque for screws is 0.3 to
0.4 N·m.
Changing the one-touch fittings
The built in fittings on the manifold can be easily changed. The clip prevents the
fittings coming off. After removing the corresponding valve, take out the clip with
a screwdriver, etc., to replace the fittings. To mount the fittings: fully insert the
fitting until it stops, then put the clip into the prescribed position.
The clip is designed to fit the VQZ1000/2000 from the side and VQZ3000 from the
end plate side.
Precaution
When pulling the fitting assembly away from the manifold base, remove the clip,
then connect a tube or plug (KQ2P- NN ) with the One-touch fitting
6 )
and pull it out holding the tube or plug. Do not hold the release bushing to avoid
damage.
When the existing type of valve is replaced with the new type of valve
(e.g., during maintenance) a conversion connector assembly is required to
convert the connecter terminal from 3 terminals to 2 terminals. This needs to
be prepared separately. (Refer to the following part number for ordering.)

onto the DIN rail and
• This valve cannot be used as an emergency shutoff valve, etc.
The valves presented in this catalogue are not designed for safety
applications such as an emergency shutoff valve. If the valves are used in this
type of system, other reliable safety assurance measures should also be
adopted.
• Extended periods of continuous energization
Please consult with SMC when using with energization for long periods
of time.
• This solenoid valve cannot be used for explosion proof applications.
• Maintenance space
The installation should allow sufficient space for maintenance activites
(removal of valve, etc.)
• Actuator drive
When an actuator, such as a cylinder, is to be driven using a valve, take
appropriate measures to prevent potential danger caused by actuator
operation.
• Pressure (including vacuum) holding
It is not usable for an application such as holding the pressure
(including vacuum) inside of a pressure vessel because air leakage is
entailed in a valve.
