- Insulated ferrule: AWG24 to AWG16 (0.25 to 1.5 mm
2
)
- Crimp height(H): 2.0 mm max Width(W): 2.7 mm max. Conductor length: 8 to 10 mm
When using the twin type ferrule, use equal-sized wires and preferred insulated ferrule.
The twin type ferrule should not be above the adjoining release hole.
●
How to insert solid wire and insulated ferrule
The wire should be pushed into the terminal block straight. No need to use the driver.
After inserting, make sure wire is fastened on to terminal block.
●
How to release wire
Use the following minus drive to release wire from terminal block.
And When releasing wire, the power source should be disconnected first.
1. Push the driver lightly into the taper of release hole.
2. Pull out the wire while the driver is pushed into release hole.
3. Pull out the driver.
Terminal block may be damaged.
1. Not push the driver into the release hole straight.
2. Not push the driver into the release hole by force of 30N and over.
3. Not tip or twist the driver pushed into release hole.

Precautions for Correct wiring
Fault Detection
When G9SE detects a fault, LED indicators blink to show the information of the fault.
When PWR indicator blinks, check and take needed measures referring to the following table. And then
apply supply voltage to G9SE.

PWR
1) Failures involving the wiring of
Safety input 1
1) Failures involving the wiring of
Safety input 2
1) Supply voltage outside the
rated value.
Expected causes of
the faults
Checking points and
measures to take
1) Check the wiring to T11 and T12.
When using stranded wire, insulated ferrule should be used. Use below insulated ferrule.
But do not use ferrule terminals if G9SE is used as UL Listing. Insert the strand or solid wire directly into the
holes on the terminal block.

Performance level and safety category
(EN ISO13849-1)
Type G9SE can construct the condition conforming to PL=e and category 4 requested by EN ISO13849-1
European standard. This category class is recognized and based on the circuits we made, so we would like you
to conform the category class with G9SE at your application once. Category is judged by the condition of the
whole control system.
・
In order to category 4
（
EN ISO13849-1
）
1) Input the signals to both of the Safety inputs (T11-T12 and T21-T22)
2) Input a signal to the Safety inputs (T11-T12 and T21-T22) through switches with Direct Opening
Mechanism. When using limit switches, at least one of them must have Direct Opening Mechanism.
And wiring must be done in a way that a short circuit between the wires of safety input can be
excluded.
3) When connecting Safety sensor with G9SE, use TYPE 4 safety sensor.
4) Input the signal through a NC contact of the contactor to Feedback/Reset input (T31-T32 for manual
reset or T31-T33 for auto reset).(Refer to '5.Examples of Application')
5) Be sure to connect
the negative terminal of DC power supply
to ground.
6) Use two safety outputs (e.g. 13-14 and 23-24) for the system construction.
6
To set Safety outputs in ON state, HIGH
state signals must be input to both of
Safety input 1 and Safety input 2.
Otherwise Safety outputs cannot be
inON state.
To set Safety outputs in ON state, ON
state signal must be input to T33.
Otherwise Safety outputs cannot be in
ON state.
To set Safety outputs in ON state, the
signal input to T32 must change from
OFF state to ON state, and then to OFF
state. Otherwise Safety outputs cannot
be in ON state.
Turns ON/OFF according to the state of
safety inputs, Feedback/Reset inputs.
During off-delay state, safety outputs
are not able to turn ON.
Off-delayed safety outputs.
(See Note1)
Off-delay time is set by off-delay preset
switch.
When the delay time is set to zero,
these outputs can be used as
non-delay outputs.
Outputs a signal of the same logic as
Safety outputs

In many case, Safety Sensor outputs include the off-shot pulse for its self test.
The following condition of test pulse is applicable as safety inputs for G9SE.
- Off-shot pulse width of the sensor, during the ON-state : 640 μs
