Safety Guidelines for Hazardous Locations

The NI 9870 is suitable for use in Class I, Division 2, Groups A, B,

C, D, T4 hazardous locations; Class I, Zone 2, AEx nA II T4 and

Ex nA II T4 hazardous locations; and nonhazardous locations only.

Follow these guidelines if you are installing the NI 9870 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 Zone 2 applications, install the

CompactRIO system in an enclosure rated to at least

IP 54 as defined by IEC 60529 and EN 60529.

NI 9870 Operating Instructions 4 ni.com

Caution For Zone 2 applications, install a protection

device between the RS232 signal cables and the NI 9870

RJ-50 jacks (ports 1–4). The device must prevent the

RS232 signal-to-signal or signal-to-COM voltage from

exceeding 35 V if there is a transient overvoltage

condition.

Caution For Zone 2 applications, install a protection

device between the external power supply and the

NI 9870 Vsup and COM pins. The device must prevent the

Vsup-to-COM voltage from exceeding 39 V if there is a

transient overvoltage condition.

Special Conditions for Hazardous Locations in Europe

This equipment has been evaluated as Ex nA IIC T4 equipment

under DEMKO Certificate No. 07 ATEX 0626664X. Each module

is marked II 3G and is suitable for use in Zone 2 hazardous

locations. If you are using the NI 9870 in Gas Group IIC hazardous

locations or in ambient temperatures of –40 °C ≤Ta ≤70 °C, you

must use the device in an NI chassis or controller that has been

evaluated as EEx nC IIC T4, Ex nA IIC T4, or Ex nL IIC T4

equipment.

Special Conditions for Marine Applications

Some modules are Lloyd’s Register (LR) Type Approved for

marine applications. To verify Lloyd’s Register certification, visit

ni.com/certification and search for the LR certificate, or

look for the Lloyd’s Register mark on the module.

Caution To meet radio frequency emission requirements

for marine applications, use shielded cables and install

the system in a metal enclosure. Suppression ferrites

must be installed on power supply inputs near power

entries to modules and controllers. Power supply and

module cables must be separated on opposite sides of the

enclosure and must enter and exit through opposing

enclosure walls.

You must connect an external power supply to the NI 9870. This

power supply provides the power for the RS232 transceivers on the

module. You can use the included female four-position pigtail to

connect to an external voltage source. Figure 1 lists the

connections between an external voltage source (of +8 V to +28 V)

and the NI 9870.
