In Case There Is No Output Voltage
There is a possibility that functions such as overcurrent protection,
over-voltage protection or overheating protection are functioning. The
internal protection circuit may operate if a large amount of surge
voltage such as a lightening surge occurs while turning ON the Power
Supply.
In case there is no output voltage, please check the following points
before contacting us:
 Checking overload protection status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
 Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least 3
minutes. Then turn it ON again to see if this clears the condition.
 Check overheating protection (350-W model):
Switch off the input power supply and switch back on after allowing
sufficient time for cooling.
Charging Batteries
If you connect a battery at the load, install overcurrent control and
overvoltage protection circuits.
Period and Terms of Warranty
Warranty Period
The Power Supply warranty is valid for a period of three years from the date of shipment from the factory.
Terms of Warranty
The warranty is valid only for the following operating conditions.
1. Average ambient operating temperature of the Power Supply: 40C max.
2. Average load rate: 80% max.
3. Mounting method: Standard mounting
* The maximum ratings must be within the derating curve.
If the Power Supply fails for reasons attributable to OMRON within the above warranty period, OMRON will repair or replace the faulty part of the
Power Supply at the place of purchase or the place where the Power Supply delivered without charge.
This warranty does not cover the following types of failures.
Recommended Replacement Periods and Periodic Replacement for
Preventive Maintenance
The recommended replacement period for preventive maintenance is greatly influenced by the application environment of the Power Supply. As
a guideline, the recommended replacement period is 7 to 10 years.* To prevent failures and accidents that can be caused by using a Power Supply
beyond its service life, we recommend that you replace the Power Supply as early as possible within the recommended replacement period.
However, bear in mind that the recommended replacement period is for reference only and does not guarantee the life of the Power Supply.
Many electronic components are used in the Power Supply and the Power Supply depends on the correct operation of these components to
achieve the original Power Supply functions and performance. However, the influence of the ambient temperature on aluminum electrolytic
capacitors is large, and the service life is reduced by half for each 10C rise in temperature (Arrhenius law). When the capacity reduction life of the
electrolytic capacitor is reached, Power Supply failures or accidents may occur. We therefore recommend that you replace the Power Supply
periodically to minimize Power Supply failures and accidents in advance.
* The recommended replacement period applies under the following conditions: rated input voltage, load rate of 50% max., ambient temperature
of 40C max., and the standard mounting method. (The fan is excluded for models with fans.)
This product model is designed with a service life of 10 years minimum under the above conditions.
(1) Failures that result from handling or operation of the Power Supply under conditions or in environments that are not given in this document
and not given in any other specifications exchanged between OMRON and the customer
(2) Failures that originate in causes other than the delivered product itself
(3) Failures caused by disassembly, modification, or repair of the Power Supply by anyone other than OMRON
(4) Failures caused by applications or uses for which the Power Supply was not originally intended
(5) Failures caused by factors that could not be anticipated with the scientific or technical knowledge available when the Power Supply was
shipped
(6) Failures caused by other causes for which OMRON is not responsible, such as natural disasters and other acts of God
This warranty is limited to the individual product that was delivered and does not cover any secondary, subsequent, or related damages.
