  • PrecautionsObserve these precautions when installing the vision controller to reduce the risk of injury or equipment damage:

    l The vision controller is intended to be supplied by a NRTLlisted power supply with a minimum output rated24VDC, 5A and must be used with the Cognex-supplied 24VDC power connector. Any other voltage creates arisk of fire or shock and can damage the components. Wire and connections must be in accordance with theseinstructions, the National Electrical Code and applicable national and local wiring standards and rules.

    l To reduce the risk of damage or malfunction due to over-voltage, line noise, electrostatic discharge (ESD), powersurges, or other irregularities in the power supply, route all cables and wires away from high-voltage powersources.

    l Do not install the vision controller in areas directly exposed to environmental hazards such as excessive heat,dust, moisture, humidity, impact, vibration, corrosive substances, flammable substances, or static electricity.

    l The system fuse is the only user-serviceable part in this product. The replacement fuse must be a Littelfuse (Part0217005) or an equivalent UL-recognized fast-blow fuse rated at 5A, low breaking capacity, and 250V. It mustalso be rated for DC operation at a voltage of 24VDC or higher. Refer to Replace the Fuse on page41 for moreinformation.

    l The vision controller does not contain any other user-serviceable parts. Do not make electrical or mechanicalmodifications to the vision controller components. Unauthorized modifications may void your warranty.

    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 bendradius is tighter than 10X the cable diameter. The bend radius must be at least six inches from the connector.

    l Changes or modifications not expressly approved by the party responsible for regulatory compliance could voidthe users authority to operate the equipment.

    l Remove power from the vision controller before connecting or disconnecting any cables or the I/O terminalblocks.

    l The maximum torque that can be applied to the I/O terminal connectors is 0.25 Nm (2.2 in-lb). Applying torqueabove this limit can damage the connectors.

    l Remove power from the vision controller before connecting or disconnecting the 24VDC power connector.

    l The maximum torque that can be applied to the 24VDC power connector is 0.6 Nm (5.3 in-lb). Applying torqueabove this limit can damage the connector.

    l Class A Equipment (broadcasting and communication equipment for office work): Seller and user shall benotified that this equipment is suitable for electromagnetic equipment for office work (Class A) and can be usedoutside the home.

    l This device should be used in accordance with the instructions in this manual.

    l All specifications are for reference purposes only and may be changed without notice.
