Page 7: Safety Points
Use the DIN rail of 35 mm in width (Model PFP-50N/-100N manufactured by OMRON). When wiring on the main body of the product, use a crimp-style terminal suitable for M3.5 screw. - Page 8 Therefore, lowering the internal temperature of the product can lengthen its life. Installing more than one Model KM1 close to each other or by arranging them in the up-down direction requires the consideration of forced cooling by, e.g., sending air to the products through a fan.
