Safety precautions
► Keep disassembled magnetic couplings away from people with pacemakers.
– Minimum distance:
2 m
► Avoid convergence of the disassembled magnetic coupling components.
► Keep magnetized parts away from the magnetic coupling.
► Always keep a disassembled magnetic coupling away from computers, data carriers, and other
electronic components.
– The magnetic coupling can influence operational reliability of electrical and electronic devi-
ces.
