18. Connect to the G9SX-NS@ only appropriate components or
devices complying with relevant safety standards corresponding
to the required level of safety category.
Conformity to requirements of safety category must be
determined as an entire system. It is recommended to consult an
authorized certification body regarding assessment of conformity
to the required safety level.
19. OMRON is not responsible for conformity with any safety
standards covering the customer's entire system.
20. Be careful not to have your fingers caught when mounting terminal
blocks.
21. The service life will depend on the switching conditions. Be sure
to check the actual operating conditions using the actual devices,
and make sure that the number of switching operations will not
cause performance problems.

1. Handle with Care.
Do not drop the product or expose it to excessive vibration or
mechanical shock. The product may be damaged and may not
function properly.
2. Storage and Operating Conditions
Do not store or use the products under the following conditions.
1. In direct sunlight
2. At ambient temperatures not between −10 and 55°C
3. At relative humidity not between 25% and 85% or under
temperature changes that could causes condensation
4. In corrosive or combustible gases
5 Where subject to vibration or mechanical shock beyond the
rated values
6. Where subject to contact with water, oil, or chemicals
7. In an atmosphere containing excessive dust, saline, or metal
powder
8. Where iron filings or powder may fall on the product
3. D40A is a class A product.In residential areas D40A may cause
radio interference, in which case the user may be required to take
adequate measures to reduce interference.

4. Always use the D40A/G9SX-NS together with the special actuator
and a G9X-NS@ Controller. If you use any other OMRON Safety
Controller, confirm applicability in the manual for the Safety
Controller.
5. Use cables with a length of less than 100 m total to connect D40A
Switches. The supply voltage to D40A may decrease by the
voltage drop depending on the cable or the wiring configuration.
Check the power-supply voltage is in the rated range.
6. Disconnect the G9SX-NS@ from the power supply when replacing
the D40A. Devices connected to the G9SX-NS@ may operate
unexpectedly.
7. Adhesion of solvent such as alcohol, thinner, trichlorobenzene or
gasoline on the product should be avoided.
Such solvents make the marking on D40A illegible and cause
deterioration of parts.
8. Do not use the D40A in a magnetic field of 1.5 mT or higher. The
D40A may not function properly.
9. Do not use the D40A in the water or in an environment
continuously exposed to water. Water may penetrate into the
D40A. (The IP67 degree of protection for this switch means that it
has been checked for penetration of water after having been left
in water for a fixed period of time.)
10. Do not use the switch or actuator as a stopper. Protect the switch
and the actuator by installing a stopper. Separate the switch and
the actuator to a distance of 1 mm or more.
11. Install the actuator and switch at an appropriate distance so that
they do not create a gap that provides access to the hazard.
