Precautions
To reduce the risk of injury or equipment damage when you install the Cognex product, observe the following
precautions:
l
The vision system requires a UL or NRTL listed power supply with a 24VDC output and meets the following rating
requirements:
l
At least 2A continuous current.
l
A maximum short circuit current of less than 8A.
l
A maximum power of less than 100VA and marked as a Limited Power Source (LPS) or National
Electrical Code (NEC) Class 2.
Any other voltage creates a risk of fire or shock and can damage the components. Applicable national and local
wiring standards and rules must be followed.
l
To reduce the risk of damage or malfunction due to over-voltage, line noise, electrostatic discharge (ESD), power
surges, or other irregularities in the power supply, route all cables and wires away from high current wiring or
high-voltage power sources.
l
Do not install Cognex products where they are directly exposed to environmental hazards such as excessive
heat, dust, moisture, humidity, impact, vibration, corrosive substances, flammable substances, or static electricity.
l
Do not expose the image sensor to laser light; image sensors can be damaged by direct, or reflected, laser light.
If your application requires the use of laser light that may strike the image sensor, a lens filter at the
corresponding laser's wavelength is recommended. Contact your local integrator or application engineer for
suggestions.
l
Changes or modifications not expressly approved by the party responsible for regulatory compliance could void
the user’s authority to operate the equipment.
l
Service loops should be included with all cable connections.
l
Cable shielding can be degraded or cables can be damaged or wear out more quickly if a service loop or bend
radius is tighter than 10X the cable diameter. The bend radius must begin at least six inches from the connector.
l
The LIGHT connector is not supported.
l
This device is certified for office use only and if used at home, there can be frequency interference problems.
l
This device should be used in accordance with the instructions in this manual.
l
All specifications are for reference purpose only and may be changed without notice.
