Check point
After purchase, check that the product and packaging are not dented or
otherwise damaged. Damaged internal parts may prevent optimum control.
Make sure that the purchased product meets the required specifications.
Provide sufficient space around the product for heat dissipation. Do not
block the vents on the product.
Do not subject the terminal screws to excessive stress (force) when
tightening them.
Make sure that there are no loose screws after tightening terminal screws to
the specified torque of 0.43 to 0.58 N·m.
Be sure to confirm the polarity for each terminal before wiring the terminal
block and connectors.
Wire the power supply inputs correctly. Incorrect wiring will result in damage
to the internal circuits.
The ambient operating temperature for the Digital Controller is −10 to
*2
55°C (with no condensation or icing).
To extend the service life of the product, install it in a location with an
ambient temperature as low as possible. In locations exposed to high
temperatures, if necessary, cool the products using a fan or other cooling
method.
Check whether the standards related to shock and vibration are satisfied at
the installation environment. (Install the product in locations where the
contactors will not be subject to vibration or shock.)
Install the product in a location that is not subject to liquid or foreign
particles entering the product.
