2.2 Mounting Cautions
To avoid problems, consider the following cautions when
mounting the PF900/901:
 Allow space for draft to release heat.
 Make sure to cool down the ambient temperature by using
forced-air cooling system when the ambient temperature
exceeds 55 C. Do not expose this instrument directly to
cool air from the forced-air cooling system.
 Do not mount this instrument directly above equipment
that generates large amount of heat (heaters, transformers,
semi-conductor functional devices, large-wattage
resistors.)
 To improve noise immunity or safety, consider the
following cautions:
High voltage equipment: Do not mount within the
same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.
 Mount PF900/901 within the range of installation position (90).
 Concern the viewing angle of the display when mounting PF900/901.
Viewing angle: Horizontal 90/vertical 90 (contrast ratio 20:1)
