Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards. Whether the products conform to the standards in the system
used by the customer, however, must be checked by the customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Preparations for Use
Timing
Check point
Details
Purchasing the product
Product appearance
After purchase, check that the product and packaging are not dented
or otherwise damaged. Damaged internal parts may prevent optimum
control.
Product model and
specifications
Make sure that the purchased product meets the required specifica-
tions.
Setting the Unit
Product installation
location
Provide sufficient space around the product for heat dissipation. Do
not block the vents on the product.
Wiring
Terminal wiring
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 0.25 to 0.30 N·m.
Be sure to confirm the polarity for each terminal before wiring the ter-
minal block and connectors.
Power supply inputs
Wire the power supply inputs correctly. Incorrect wiring will result in
damage to the internal circuits.
Operating environment
Ambient temperature
The ambient operating temperature for the product is
−
10 to 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 prod-
ucts using a fan or other cooling method.
Vibration and shock
Check whether the standards related to shock and vibration are satis-
fied at the installation environment. (Install the product in locations
where the conductors will not be subject to vibration or shock.)
Foreign particles
Install the product in a location that is not subject to liquid or foreign
particles entering the product. If sulfide, chlorine, or other corrosive
gases are present, remove the source of the gas, install a fan, or use
other countermeasures to protect the product.
