15. uman life body and assets will not be damaged if the optical fiber breaks or the characteristics deteriorate Do not use this optical fiber cable for applications that ensure safety such as for emergency stop or ultimate limit signals Before starting use 1 Do not use outside the of working temperature range The optical characteristics of the optical fiber could deteriorate if the optical fiber is left at high temperatures for a long time or if thermal stress is applied Make sure that the cable does not contact objects that could reach high temperatures such as CV cables or hot water pipes Do not lay the cable where hot steam could be sprayed When designing the optical cable laying path take the operating temperature into consideration and determine the route and laying methods 2 Do not use under the minimum allowable bend radius The optical fiber could break or the optical characteristics could deteriorate if the cable is used under the minimum allowable bend radius Even if the optical fiber does not break or the optical characteristics deteriorate immediately adverse effects could appear over time Do not vigorously bend the cord section at the optical connector under head When designing the optical cable laying path or designing the cabinet for storing the cable take the minimum allowable bend radius into consideration and determine the laying methods the piping path pit and trough size and the cabinet size 3 Do not
16. use over the allowable side pressure The optical fiber could break or the optical characteristics could deteriorate if the cable is used over the allowable side pressure Even if the optical fiber does not break or the optical characteristics deteriorate immediately adverse effects could appear over time Determine the route and laying methods so that a constant side pressure is not applied on the optical cable such as when the cord and cable section are fastened tightly with a band when other cables are stacked on the cable or when the trough cover is directly placed on the cable 4 Do not twist the optical cable Twisting the cable will cause the transmission loss to increase or could result in breakage Do not twist the cable more than once every 5m 5 Do not place objects on the connector Do not place objects on the connector or sandwich the cable with tools The transmission loss could increase or the cable could break 6 Do not leave the connector end bare The transmission loss will increase if the connector end is damaged or dust comes in contact Attach the enclosed dust cap when not using the cable Before connecting the connector wipe the end off with a piece of new gauze etc wetted with alcohol 7 Do not apply force on the connector connection or on the connector under head If force is applied on the connector connection or connector under head or if high tension twisting or bending is applied the transmiss
