2-4 Wiring
●Take countermeasure against the system to be applied for this device so as not
to carry out the dangerous performance caused by the earth failure. Failure to
do so could cause invalid for the system stop, resulting in death or serious injury.
●In order that the output is not turned ON due to earth fault of control output 1 / 2
(OSSD 1 / 2) wires, be sure to ground to 0V side (PNP output) / +24V side (NPN
output).
Use a safety relay unit or an equivalent control circuit in safety for FSD.
2-4-1 Power Supply Unit
Wire correctly using a power supply unit which conforms to the laws and stan-
dards of the region where this device is to be used. If the power supply unit is
non-conforming or the wiring is improper, it can cause damage or malfunction of
this device.
A specialist who has the required electrical knowledge should perform the wiring.
The power supply unit must satisfy the conditions given below.
1) Power supply unit authorized in the region where this device is to be used.
2) Power supply unit SELV (safety extra low voltage) / PELV (protected extra low voltage) con-
forming to EMC Directive and Low-voltage Directive (only for requiring CE marking conforma-
tion).
3) Power supply unit conforming to the Low-voltage Directive and with an output of 100VA or less.
4) The frame ground (F.G.) terminal must be connected to ground when using a commercially
available switching regulator.
5) Power supply unit with an output holding time of 20ms or more.
6) In case a surge is generated, take countermeasures such as connecting a surge absorber to
the origin of the surge.
7) Power supply unit corresponding to CLASS 2 (only for requiring CTÜVUS Mark conformation).

<Output waveform [Control outputs 1 / 2 (OSSD 1 / 2) are ON]>
When the sensor is ON, the controller self-diagnoses the output circuit.
The output transistor is cyclically OFF. (Refer to the gure below.)
When feedback of the OFF signal is given, the controller evaluates that the output circuit is nor-
mal. If feedback of the OFF signal is not given, the controller evaluates that the output circuit or
wiring has an error and the control outputs 1 / 2 (OSSD 1 / 2) maintains OFF status.
Perform connection paying attention to the input response time of the unit con-
nected to this device. The unit may malfunction due to OFF signal of this device.

2-4-3 Connecting to the Terminal Block of the Controller
●In connection to the terminal block of the controller, mount a single wire or stranded wire (lead
wire) with a ferrule (sleeve) terminal (prepared separately) as shown in the gure below, and
insert it to the back of the hole.
●When it is correctly inserted, it is locked and not removed by pulling. If it is pulled with strong
force, it may be disconnected.
●To connect a stranded wire (lead wire) without using a ferrule (sleeve) terminal, mount it
while holding the release button.
●To disconnect a single wire or stranded wire (lead wire), pull out the single wire or stranded
wire (lead wire) while pressing the release button.
●0.2 to 1.5mm2(AWG 24 to 16) is recommend for single wire or stranded wire (lead wire).

2-4-4 Connection / Removal of Controller and Safety Liquid Leak Sensor SQ4-A Series
When wiring safety liquid leak sensor to this device, mount easy insulation displacement con-
nector CN-EP□ (optional) to safety liquid leak sensor.
Used easy insulation displacement connector depends on type of safety liquid leak sensor,
so refer table below. Also, In case the cable of the safety liquid leak sensor is extended, use
different type of displacement conecotor. Choosing easy insulation displacemnet conector
depends on the wire cover diameter.

Step 1 Process the cable as shown in the gure below.
Step 2 Insert the wire into the wire inlet of easy insulation displacement connector until its end
comes in contact with the back.
Step 3 Crimp the easy insulation displacement connector with pliers.
• Place pliers parallel to the easy insulation displacement connector and crimp the
connector as shown in the gure below.
• Be careful not to damage the wire with pliers.
• Crimp the connector carefully so that the wire may not be disconnected.

Step 4 Pull the wire gently to conrm that the wire may not be disconnected.
A easy insulation displacement connector that has been crimped once cannot
be reused.
Use optional easy insulation displacement connector CN-EP2 (for PVC cable, 5
pcs. / set) and CN-EP3 (for PFA cable, 5 pcs. / set) or recommended parts.
<Recommended easy insulation displacement connector>

• For PFA cable: 3-1473562-4
Step 5 Insert the easy displacement connector into sensor connector No. 1 of this device.
Maximum 4 safety liquid leak sensor can be connected.
●When connecting to the sensor connector, be sure connect the safety liquid
leak sensors from No. 1 in order. If you connect in disorder, the controller be-
comes lockout status and does not work.
●In case connecting PNP output type of safety liquid leak sensor, set to PNP side
the control output polarity selection switch of this device. Also, in case connect-
ing NPN output type set to PNP side the control output polarity selection switch
