4.2 Mounting Position within Panel
Mount this instrument in the panel most suited to the environment and to facilitate operation and
maintenance.
(1) Mounting precautions
Temperature considerations
•
Allow enough ventilation space.
•
Do not mount this instrument directly above equipment which
generates heat (heaters, transformers, large resistors, etc.).
•
If the ambient temperature rises above 50
°
C, cool the panel
inside using a forced fan or cooler. However, do not expose the
control unit directly to the air. If exposed, this may cause an
error.
Humidity considerations
Condensation may form in the instrument due to rapid changes in temperatures by turning the air
conditioner on or off. Such condensation can cause instrument malfunctions due to insulation
deterioration or shorting. To prevent the risk of condensation, always turn on the power or pre-heat
the instrument using space heaters.
Panel vibration or impact considerations
•
Isolate the panel from external vibration or shock using rubber vibration insulators.
•
If the electromagnetic switches cause vibration when they operate within the panel, isolate the
switches using rubber vibration insulators.
Environment considerations
If dust, steam, soot or poisonous gas exists, purge the panel inside using clean air and create a slight
positive pressure inside the panel to keep out the harmful gases.
Ease of operations and maintenance considerations
To ensure safety for maintenance and operation, separate the instrument from high voltage equipment
or rotating machinery where possible.
Anti-noise considerations
•
Do not install the instrument in a panel where high-voltage
equipment is installed.
•
Separate the instrument from rotating machinery lines by
more than 200 mm.
