3-2-1 Installation Site Conditions

Automatic Restart
When the supply voltage recovers to a value higher than 85% of the rated value,
operations resumes automatically.
Duration of power interrupt
(Below 85% of rated voltage)
Note The CPM1 may repeat stop/start operations if the supply voltage of less than
85% of the rated value gradually goes up or down. If this affects the equipment,
etc., provide a protection circuit which shuts off the output if the supply voltage is
not above the rated value.
Time Up to the Start of Operation
The time from when the power supply is turned on to when the operation starts
varies depending on the operation conditions such as power supply voltage,
configuration, ambient temperature, etc. The minimum time is approximately
300 ms.
The CPM1 is resistant to harsh conditions and highly reliable, but installing the
PC in a favorable site will maximize its reliability and operating lifetime.
Be sure to install the CPM1 correctly, as outlined in this manual. Failure to do so
may result in Unit malfunction.
Note Do not install the CPM1 under any of the following conditions.
• Locations subject to direct sunlight.
• Locations subject to a temperature below 0°C or over 55°C.
• Locations subject to a humidity below 10% or over 90%.
• Locations subject to condensation as the result of severe changes in tempera-
ture.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to shock or vibration.
• Locations subject to exposure to water, oil, or chemicals.
Be sure that the conditions at the installation site conform to the CPM1's general
specifications. Refer to 2-1-1 General Specifications for details.
Note Provide proper shielding when installing in the following locations:
• Locations subject to static electricity or other sources of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radiation.
