Visual Display Unit (Vdu); Degree Of Protection - HEIDENHAIN TNC 415 Technical Manual

2.5.2 Visual display unit (VDU)

When mounting the VDU it must be remembered that this unit is very sensitive to magnetic pick-up.
The picture position and geometry can be disturbed by stray magnetic fields. Alternating fields cause
periodic movement or distortion of the picture.
For this reason, keep a minimum distance of 0.5 m between the VDU casing and the source of any
disturbance (e.g. permanent magnets, motors, transformers etc.)
