This document explains how to connect to the NI 9860.
Note Before you begin, complete the software and
hardware installation procedures in your chassis
documentation.
Note The guidelines in this document are specific to
the NI 9860. The other components in the system might
not meet the same safety ratings. Refer to the
documentation for each component in the system to
determine the safety and EMC ratings for the entire
system.
Safety Guidelines
Operate the NI 9860 only as described in this document.
Hot Surface This icon denotes that the component
may be hot. Touching this component may result in
bodily injury.
Caution Do not operate the NI 9860 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
The NI 9860 is suitable for use in Class I, Division 2, Groups A,
B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4
and Ex nA IIC T4 hazardous locations; and nonhazardous
locations only. Follow these guidelines if you are installing the
NI 9860 in a potentially explosive environment. Not following
these guidelines may result in serious injury or death.
Caution Do not disconnect I/O-side wires or
connectors unless power has been switched off or the
area is known to be nonhazardous.
Caution Do not remove modules unless power has
been switched off or the area is known to be
nonhazardous.
Caution Substitution of components may impair
suitability for Class I, Division 2.

Caution For Division 2 and Zone 2 applications,
install the system in an enclosure rated to at least IP54
as defined by IEC/EN 60079-15.
Special Conditions for Hazardous Locations Use in
Europe and Internationally
The NI 9860 has been evaluated as Ex nA IIC T4 Gc equipment
under DEMKO Certificate No. 12 ATEX 1202658X and is
IECEx 14.0089X certified. Each NI 9860 is marked II 3G and
is suitable for use in Zone 2 hazardous locations, in ambient
temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9860
in Gas Group IIC hazardous locations, you must use the device in
an NI chassis that has been evaluated as Ex nC IIC T4, Ex IIC
T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.
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 60664-1.
Caution The system shall be mounted in an
ATEX/IECEx-certified enclosure with a minimum

ingress protection rating of at least IP54 as defined in
IEC/EN 60079-15.
Caution The enclosure must have a door or cover
accessible only by the use of a tool.
Wiring the NI 9860
The NI 9860 has two ports for connecting to NI-XNET CAN/LIN
Transceiver Cables (required to connect to the CAN/LIN bus)
and a two-position connector for use with an external power
supply.
For more information about transceiver cables, refer to the
NI-XNET CAN/LIN Transceiver Cables page on ni.com.
The NI 9860 requires an external power supply of +9 to +30 V to
power the transceiver cables. Supply power to the NI 9860 VSUP
connector on the module front panel using the supplied power
cable. The exposed lead wires at the end of the power cable are
routed as follows: black wire—COM, red wire—VSUP. The
power cable lead wires may be daisy-chained to the controller
power port when the controller supply voltage is in the
appropriate range.

Note Power on VSUP is required for transceiver cable
operation.
Note When using more than four transceiver cables
with your CompactRIO chassis, refer to the NI-XNET
CAN/LIN Transceiver Cables page on ni.com for
mounting guidelines to limit the thermal impact to your
CompactRIO system.
The following figure shows the NI 9860 with Port 1 connected to
an NI-XNET CAN HS/FD Transceiver Cable and the
two-position connector connected to the power cable. The breaks
in the cables represent additional cable length.

Inserting and Removing the NI-XNET
Transceiver Cable
The NI-XNET Transceiver Cable connects to a host device with
an active latching connector. To connect the NI-XNET
Transceiver Cable to a host device, push the connector assembly
into the host receptacle until the internal latch snaps into position.
The latch emits an audible click when engaged. To remove the
NI-XNET Transceiver Cable, push the lock ejector forward to
disengage the latch and simultaneously pull the NI-XNET
Transceiver Cable, as shown in the following figure.
