Ambient Temperature
The ambient temperature is decided from the multiple measurement points which are a 50mm-
distance from the CPU unit.
During the operation, adjust the air current to make certain that the temperatures measured in
the points stay within the specified temperature. (-20 - +60 °C)
*As for the vertical installation with an angle of 90° to the left/right or the horizontal Installation,
the ambient temperature should be -20 - +55°C.
CAUTION
Be certain the following requirements are satisfied when using the product.
- Up to overvoltage category 2 - Indoor use
- Altitude up to 2000m - Applicable POLLUTION DEGREE 2
When using the product at high altitudes, refer to the relational expression below to find an
appropriate ambient temperature. The heat dissipation decreases due to air pressure drop
and could lead to damages or a shorter product life.
- Ambient temperature = 60[°C] - 0.005 x altitude [m]
An Example) 60°C - (0.005 x 2000m) = 50°C (Ambient temperature)
The product is an open-type device (a device designed to be housed inside other equipment)
and must always be mounted inside a mechanical enclosure having enough strength.
Note that although the ambient temperature is within the specified range, an operational
malfunction may occur if there is other device generating high heat; the radiation will
influence the product to increase its temperature.
Do not install this product into the fully-sealed space except the case in which the internal
temperature is adjustable by equipment such as air conditioner. Long-term usage might
increase the temperature of the product and lead to malfunctions or other troubles.
When using the product in a high temperature environment, its life time will be shortened.
Perform the forced air cooling to counteract.
4. Installation and Removal of I/O
Module and Blank Panels
Installation procedure
Paying attention to the horizontal orientation of the I/O module, insert the resin groove into
the rail of the CPU unit that has been installed on a DIN rail or that has been screwed into place,
and then push the I/O module in until it clicks.
Removal procedure
Press in the hooks at the top and bottom of the I/O module, and then pull it toward you and
out of the CPU unit that has been installed on a DIN rail or screwed into place.
CAUTION
Always confirm the PWR-LED of the CPU unit is turned off before installing or removing the
module.
5. Connecting to an External Device
When connecting the product to an external device, use the supplied connector.
When wiring the connector, strip off 8 mm ± 0.5 mm of the wire's covering, and then insert this
stripped part into the connector's opening.
While pushing the orange part in the center of the connector with a precision screwdriver or a
similar tool, insert the cable into the round connection hole. After that, release the pushed part
to fix the cable in place.
You can also insert cables without pushing on the orange part of the connector by using a
ferrule terminal.
CAUTION
Removing the connector plug by grasping the cable can break the wire.
Please use copper wires that withstand the temperature of 75 degrees Celsius and higher.
