11. Install the actuator and switch at an appropriate distance so that
they do not create a gap that provides access to the hazard.
Correct
12. Where two or more Switches are mounted side-by-side, they must
be no closer than 25 mm.
25 mm min.
13. Check that the machine is stopped whenever the interlocked
guard door is open.
14. Do not mount the switch and actuator on magnetic materials,
otherwise it may affect the operating distance.
Distance from surface of
magnetic body
0 to 5 mm
5 mm or longer
15. Tighten all screws to the specified torque by using non-magnetic
M4 screws and washer for the installation of the switch and
actuator. After installation and using, the actuator and switch
fixing screws must be coated with tamper proof varnish or similar
compound. Using anaerobic locking compounds can have a
detrimental effect on the plastic switch case if the compounds
come into contact with the switch case.

16. Wiring
1. Use the following to wire to the product.
Stranded wire (flexible wire): 0.2 to 2.5 mm
AWG12)
Solid wire (steel wire): 0.2 to 2.5 mm
2. When an auxiliary output is not used, cut off the wiring and
cover it with tape so that it does not contact other terminals.
17. Mounting
Mount the G9SX-NS to a DIN rail using End Plates (PFP-M, not
included with the product) so that the G9SX-NS does not fall off of
the rails due to vibration or other causes, especially when the
length of DIN railing is short compared to the width of the
G9SX-NS@.

18. The following space must be provided around the G9SX-NS@ to
enable applying the rated current to the outputs of the G9SX-
NS@, to ensure sufficient ventilation, and to enable wiring:
1. At least 25 mm between side surfaces of the G9SX-NS@
2. At least 50 mm above the top surface of the G9SX-NS@ and
below the bottom surface of the G9SX-NS@.
25 mm min.
19. Wiring
1. G9SX-NS@-RT (with Screw Terminals)
• Use the following to wire the G9SX-NS@-RT.
Solid wire
(steel wire)
Stranded wire
(flexible wire)
• Tighten each screw to the specified torque of 0.5 to 0.6 N
or the G9SX-NS@ may malfunction or generate heat.
• Strip the wire for no longer than 7 mm.
2. G9SX-NS@-RC (with Spring-cage Terminals)
• Use the following to wire the G9SX-NS@-RC.
Solid wire
(steel wire)
Stranded wire
(flexible wire)
3. Logical AND Connections
• Use VCTF cables or shielded cables for logical AND connect
ions between Units.
20. Connecting G9SX-EX@-@ Expansion Units
1. Remove the terminating connector from the connector on the
G9SX-NSA222-T03@. Insert the connector on the connecting
cable of Expansion Unit into the connector on the G9SX-NSA222-
T03-@.
2. Connect the terminating connector to the connector on the
Expansion Unit at the end position.
When the G9SX-NSA222-T03-@ is used without Expansion
Units, leave the terminating connector on the G9SX-NSA222-
T03-@.
3. Do not remove the terminating connector or connecting cables
of Expansion Units while the system is operating.
4. Before applying the supply voltage, confirm that the connectors
are locked firmly.
5. All of the Expansion Units must be supplied with its specified
voltages within 10 s after the connected G9SX-NSA222-T03-@
is supplied with voltage.
Otherwise, the G9SX-NSA222-T03-@ will detect a power
supply error for the Expansion Units.
21. Use cables with a length of less than 100 m total to connect the
safety inputs, feedback/reset inputs, and logical AND connection
inputs and outputs.
22. Set the time duration of OFF-delay to an appropriate value that
does not cause the loss of safety functions of system.
