Precautions for Correct Use
Make sure to use the Safety Mat UM series in combination with the
Safety Mat Controller MC series or the Safety Controller G9SP.
Handle with care
1. Do not drop the Safety Mat to the ground or expose to excessive
vibration or mechanical shocks. The Safety Mat may be damaged
and may not function properly.
2. Do not apply loads on a certain location of the Safety Mat for a long
period of time. It may damage the Safety Mat.
3. Do not use the Safety Mat submerged in water or in locations con-
tinuously subject to splashes of water.
4. Store the Safety Mat in a vertical (standing) position prior to install
so that loads are not applied to the Safety Mat.
Solvents
Adhesion of solvent such as alcohol, thinner, trichloroethane or
gasoline on the product should be avoided.
Such solvents make the marking on the Safety Mat illegible and cause
deterioration of parts.
Storage conditions of the Safety Mat
Do not store in such conditions stated below.
1. In direct sunlight
2. At ambient temperatures out of the range of -37 to 66°C.
3. At air pressure out of the range of 86 to 106 kPa.
4. In corrosive or combustible gases
5. With vibration or mechanical shocks out of the rated values.
6. Under splashing of oil, chemicals
7. In the atmosphere containing dust, saline or metal powder.
The Safety Mat may be damaged and may not function properly.
Storage conditions of the Safety Mat Controller
Do not store in such conditions stated below.
1. In direct sunlight
2. At ambient temperatures out of the range of 0 to 55°C.
3. At relative humidity out of the range of 90%RH or under such tem-
perature change that causes condensation.
4. At air pressure out of the range of 86 to 106 kPa.
5. In corrosive or combustible gases
6. With vibration or mechanical shocks out of the rated values.
7. Under splashing of water, oil, chemicals
8. In the atmosphere containing dust, saline or metal powder.
The Safety Mat Controller may be damaged and may not function
properly.
Wiring of the Safety Mat Controller
1. Use the following to wire to the Safety Mat Controller
• Stranded wire (Flexible wire): 0.2 to 2.5 mm
• Solid wire: 0.2 to 2.5 mm 2
• Strip the cover of wire no longer than 7 mm.
2. Tighten each screw with a specified torque of 0.4 to 0.5 N·m, or the
Safety Mat Controller may malfunction or generate heat.
3. Ground the negative side of the power supply. A controller with the
positive side grounding will not work.
Mounting of multiple Safety Mat Controllers
1. In closely contacted mounting, the rated carry current is 3 A. Use
at 3 A or less voltage.
2. When applying more than 3A , place the mats farther than 25 mm
from the nearest MC3.
Mounting of the Safety Mat Controller to DIN rails
Use end plates (PFP-M: sold separately) on both ends of MC3.
Use of air valve
1. After installing a mat, loose the air valve on the surface of the mat
for 30 seconds or more in order to make the internal air pressure
equal to external air pressure.Then, close the air valve.
2. Turn the air valve with a torque at 1.5 N·m or less.
3. Do not store or use the the mat with loose air valve. It may allow
water penetration.
Mounting of the Safety Mat
1. Use- dedicated trims to secure the circumference of the Safety Mat
for installation.
2. Do not install the Safety Mat on an environment with a projection.
Install it on a flat surface.
3. Do not pull the cables to lift or move the Safety Mat.
4. Do not use the Safety Mat with a cover on it.
Others
This is a Class A product (Product in industrial setting). Use of the
product in residential setting may cause radio disturbance. In such
case, take appropriate measures.

Safety Category

Certification has been obtained for EN ISO13849-1: 2015 PLd/Safety
Category 3 for a system consisting of combination with the Safety Mat
Controller MC series or the Safety Controller G9SP.
If you use a UM Safety Mat and MC3 Safety Mat Controller which is
selected automatic reset mode, a separate safety controller is
required to achieve a category 3, PLd safety circuit if external safety
relays or magnetic contactors are connected.
