Conformance to EC Directives

6 Conformance to EC Directives
6-1 Applicable Directives
6-2 Concepts
• When wiring crossovers between terminals, the total current for both ter-
minals will flow in the line. Check the current capacities of all wires before
wiring crossovers.
• The following precautions apply to Power Supply Units with Replacement
Notification.
• When the LED display on the front of the Power Supply Unit starts to
alternately display "0.0" and "A02" or the alarm output automatically
turns OFF, replace the Power Supply Unit within 6 months.
• Separate the alarm output cables from power lines and high-voltage
lines.
• Do not apply a voltage or connect a load to the alarm output that ex-
ceeds the rated voltage or load.
• Maintain an ambient storage temperature of − 20 to 30 ° C and humidity
of 25% to 70% when storing the product for longer than 3 months to
keep the replacement notification function in optimum working condi-
tion.
• Always use the standard installation method. A nonstandard installa-
tion will decrease heat dissipation, delay the replacement notification
signal, and may degrade or damage the internal elements.
• Design the system so that the power supply capacity of the Power Supply
Unit is not exceeded.
• Do not touch the terminals on the Power Supply Unit immediately after
turning OFF the power supply. Electric shock may occur due to the resid-
ual voltage.
• EMC Directives
• Low Voltage Directive
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 (see the following note). 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.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility):
EMI (Electromagnetic Interference):
EN61000-6-2
EN61000-6-4
(Radiated emission: 10-m regulations)
