Safety Guidelines for Hazardous Locations

The NI 9238 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 9238 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.
