5.3.12 Mounting Environment
KV PLCs are highly reliable. Consider, however, the following before installation to
get the best result from your PLC.
Locations
Do not install your PLC in the following places:
•
Places directly exposed to sunlight
•
Places where the temperature drops below 0°C (32°F) or exceeds 50°C (122°F)
•
Places where the humidity drops below 35%RH or exceeds 85%RH
•
Places where condensation occurs due to sudden temperature drop
•
Places where there is corrosive or flammable gas
•
Places exposed to airborne dust, corrosive substances such as salt, metal
particles, or oil
•
Places where the PLC may be subjected to strong vibration or impact
•
Places where water, oil, or chemicals may splash the PLC
•
Places exposed to strong magnetic or electric field.
Installation site inside the panel
Ambient temperature
•
The operating temperature range of the PLC basic unit is 0 to 50°C (32 to122°F)
(No freezing).
•
The operating temperature range becomes 0 to 45°C (32 to103°F) when the PLC
is operated with the handheld programmer connected (No freezing).
•
Provide enough space for proper ventilation.
•
Do not install the PLC directly above equipment which emits large amount of
heat (heater, transducer, large capacitor, etc.).
•
Provide a fan or air conditioner, if the temperature exceeds 50°C (122°F).
Improving noise resistance
•
Do not install the PLC and high voltage equipment in the same control panel.
•
Isolate the PLC as far as possible from the power cables.
•
Do not route ducts or wires between the basic unit and the expansion units in
case that units are mounted side by side.
Accessibility
Isolate the PLC as far as possible from high voltage equipment and drive equipment
in order to ensure safe and easy access for adjustment and maintenance.
Wiring
M3.0 screws are employed from the terminals.
Use crimp terminals of the following types. (units: mm)
