Safety Guidelines

Operate the product only as described in this document.

Caution This icon denotes a caution, which advises you to consult documentation where this symbol is marked.
Caution Do not operate this product in a manner not specified in this document. Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to NI for repair.

Safety Guidelines for Hazardous Locations

These products have been evaluated as Ex ec IIC T4 Gc equipment and are CCC certified. Each product is suitable for use within ambient temperatures of -40 °C ≤ Ta ≤ 70 °C in either nonhazardous locations or Zone 2 hazardous locations.

Follow these guidelines if you are installing the product in a potentially explosive environment. Not following these guidelines may result in serious injury or death.

Caution Do not disconnect bus-side connector unless power has been switched off or the area is known to be nonhazardous.
Caution Do not unplug the transceiver cable unless power has been switched off or the area is known to be nonhazardous.
Caution Substitution of components may impair suitability for Zone 2.
Caution You must make sure that transient disturbances do not exceed 140% of the rated voltage.
Caution The system shall only be used in an area of not more than Pollution Degree 2, as defined in IEC/EN 60664-1.
Caution The system shall be mounted in a CCC-certified enclosure with a minimum ingress protection rating of at least IP54 as defined in GB/T3836.1.
Caution The enclosure must have a door or cover accessible only by the use of a tool.
Caution (TRC-8542/8543) For Zone 2 applications, install a protection device between the CAN bus and the product CAN pins. The device must prevent the CAN Port-to-COM voltage from exceeding 55 V if there is a transient overvoltage condition.
Caution (TRC-8546) For Zone 2 applications, install a protection device between the LIN bus and the product LIN pins. The device must prevent the LIN Port-to-COM voltage from exceeding 55 V if there is a transient overvoltage condition.
