Safety Precautions
Meaning of Warning Sign
The following warning sign is used in this manual.
Indicates a potentially hazardous situation which,
if not avoided, will result in minor or moderate
WARNING
injury, or may result in serious injury or death.
Additionally there may be significant property
damage.
Alert Statements
WARNING
Machine may start operating and may result serious injury
or death. Do not put the actuator close to the switch when
the door is opened. Also make sure to install D40Z to
minimize defeat possibilities. For required measures, refer
to ISO 14119 and other relevant standards and regulations.
Precautions for Safe Use
(1) Disconnect D40Z from power supply when wiring D40Z. Failure to do
so may cause unexpected operation of devices connected to D40Z.
(2) Do not operate D40Z with flammable or explosive gas.
(3) Incorrect wiring may lead to loss of safety function. Wire
conductors correctly and verify the operation of D40Z before using
the system in which D40Z is incorporated.
(4) Auxiliary monitoring output is NOT safety output. Do not use auxiliary
monitoring output individually for any safety function. Such incorrect
use causes loss of safety functions of D40Z and its relevant systems.
(5) After installation of D40Z, qualified personnel should verify to see that the
installation, inspection, and maintenance are properly performed. The qualified
personnel should be qualified and authorized to secure the safety on each
phases of design, installation, running, maintenance and disposal of system.
(6) Qualified personnel, who are familiar to the machine in which
D40Z is to be installed, should conduct and verify the installation.
(7) Be sure to inspect D40Z daily and every 6 months. Otherwise,
serious injury may possibly occur due to a system malfunction.
(8) Do not dismantle, repair, or modify D40Z. Doing so may lead to
loss of its safety functions.
(9) Do not apply DC voltages exceeding the rated voltages, nor any
AC voltages to D40Z.
(10) Use a DC supply satisfying the requirements given below to
prevent electric shock.
- DC power supply or transformer with double or reinforced
insulation, for example, according to IEC/EN 62368 or IEC/EN
61558.
- A DC supply satisfying the requirements for class 2 circuits or
limited voltage/current circuits stated in UL 508.
(11) Use only appropriate components or devices complying with
relevant safety standards corresponding to the required
performance level and safety category. Conformity to requirements
of the performance level and safety category must be determined as
an entire system. It is recommended to consult a certification body
regarding assessment of conformity to the required safety level.
Precautions for Correct Use
(1) Always use D40Z with dedicated actuator (D40Z-1C-A) and dedicated
controller to comply with the requirements of EN ISO 13849-1.
(2) Handle with care
Do not drop D40Z to the ground or expose to excessive vibration or
mechanical shocks. Doing so may damage D40Z and cause failure.
(3) Conditions of storage and usage
Do not store or use D40Z under the following conditions. Doing so
may damage D40Z and cause failure.
1) In direct sunlight
2) At ambient temperatures out of the range of -10 to +65°C
3) At relative humidities out of the range of 25% to 85% or under
such temperature change that causes condensation.
4) In corrosive or combustible gases
5) With vibration or mechanical shocks out of the rated values.
6) Under splashing of oil or chemicals
7) In the atmosphere containing dust, saline or metal powder.
8) Where steel scrap or metal powder may fall directly to D40Z.
(4) Do not use D40Z at altitudes over 1,000 meters.
(5) Do not use to connect other switches or sensors to the wire
conductors of D40Z.
(6) Disconnect D40Z and the controller connected to D40Z from power
supply when replacing D40Z. Failure to do so may cause
unexpected operation of devices connected to D40Z.
(7) Keep D40Z from solvent such as alcohol, thinner, trichloroethane or
gasoline. Such solvents make the marking on D40Z illegible and
cause deterioration of parts.
(8) Do not use D40Z in the magnetic field of 1.5 mT or more, otherwise
D40Z may not function properly.
(9) Do not use D40Z in the water or continuous water exposure environment,
otherwise water may leak into D40Z. (An enclosure of IP67 rating, which
D40Z is rated, protects against temporary immersion in water.)
(10) Do not use D40Z switch or actuator as a stopper. Use a stopper to
protect the switch and the actuator. Keep a distance of at least
1mm between the switch and the actuator.
(11) Be sure to install D40Z switch and actuator in such as appropriate
distance that does not create a gap accessible to the hazard.
(12) When two or more Switches are mounted side-by-side, they must
be no closer than 50 mm in the X, Y, and Z directions.
50mm min.
50mm min.
(13) Be sure that the machine is stopped whenever the guard door
is open.
(14) Installing the switch and actuator on a metallic material may affect the
operating distance. In addition, any instruments nearby that generate strong
radio waves or magnetic fields may affect the operating distance via the
metal. Do not install the switch and actuator directly on a metallic material.
If installation on a metallic material is necessary, be sure to check the effect
on the operating distance before use. Reference values for the effects of
installation on a metallic material.
Metallic material
Operating distance
Iron
Approximately 75% of the original value
Aluminum
Approximately 85% of the original value
Stainless steel
Approximately 85% of the original value
(Non-magnetic substance)
It is recommended that the switch and actuator unit be separated
at least 10 mm from any metal parts or metallic materials.
(15) Use M4 screws and washers to install the switch and actuator.
Tighten the screws with a specified torque. After installing and
commissioning, coat the switch-actuator fixing screws with
tamper-proof varnish or similar compound for locking. Using
anaerobic locking compounds can have a detrimental effect on
the plastic switch case if the compounds contact with the switch case.

(16) Wiring:
1.Use conductors of the following sizes to wire D40Z:
-Stranded wire: 0.2 to 2.5mm
AWG24 to AWG12
2
-Solid wire: 0.2 to 2.5mm
AWG24 to AWG12
2
2.When not using auxiliary output, cut off the unused conductors and
protect by insulating-taping to prevent contacting with other terminals.
3.When you use an additional cable of 20m or longer, use a
multiconductor cable to group the white, black, brown, and
blue lines together.
(17) Use cables of a total length of 100m max. to connect multiple
D40Z switches. However, the total length of 200m max. is possible
depending on the number of D40Z switches connected. The
supply voltage to D40Z may decrease by the voltage drop
depending on the cable or the wiring configuration. Check the
power-supply voltage is in the rated range.

Note. The wiring length between the products must be 100m max.
(18) In a residential environment, this product may cause radio
interference, in which case the user may be required to take
adequate measures.
(19) D40Z may not function properly in surrounding environment with strong
electromagnetic equipment such as RFID system, proximity sensor, motor,
inverter, and switching power supply. If you use D40Z near such equipment,
be sure to verify effects of such equipment on D40Z before using.
(20) Handle cables with care:
1) For bending cables, it is recommended to bend them with a
radius of bend no less than six times the cable outer diameter.
2) Do not apply a tensile strength of 50N or greater to the cables.
(21) To determine safety distance to hazards, take into account the
delay of non-contact door switch output caused the response time.
(22) If there is any machine that has a large surge current (e.g., a motor) near
D40Z, connect a surge absorber to D40Z between the blue and the other
cables (white, black, and brown), respectively, and between the yellow and
the gray cables. Suggested surge absorber's specification is as follows:
- Peak pulse power: 600W (10/1000µs) or more
(Per IEC61000-4-5(surge immunity))
- Breakdown voltage: 27-33V
