• Use clearly identified cable I-
Y (St) Y n x 2 x 0,8 mm or comparable and
employ only shielded twisted pair cables with special designation for fire
detection, and consider furthermore the requirements of the local standard!
• The shielding must be connected for EMI protection of the cable!
• All voltage and signal lines must be secured to prevent slipping by using a
suitable attachment materials such as plastic cable binders.
• Take care to ensure that no cables are pinched or damaged.
