National Instruments FP-Al-110 用户手册

© National Instruments Corp.

•

Operate the [c]FP-AI-110 only at or below Pollution Degree 2. 
Pollution Degree 2 means that only nonconductive pollution 
occurs in most cases. Occasionally, however, a temporary 
conductivity caused by condensation must be expected.

•

Operate the [c]FP-AI-110 at or below Measurement 
Category II. Measurement Category II is for measurements 
performed on circuits directly connected to the low-voltage 
installation. This category refers to local-level distribution, 
such as that provided by a standard wall outlet.

The [c]FP-AI-110 is suitable for use in Class I, Division 2, Groups 
A, B, C, and D hazardous locations; Class 1, Zone 2, AEx nC IIC 
T4 and Ex nC IIC T4 hazardous locations; and nonhazardous 
locations only. Follow these guidelines if you are installing the 
[c]FP-AI-110 in a potentially explosive environment. Failing to 
follow these guidelines may result in serious injury or death.

Do not disconnect I/O-side wires or connectors 

unless power has been switched off or the area is known 
to be nonhazardous.

Do not remove modules unless power has been 

switched off or the area is known to be nonhazardous.

Substitution of components may impair 

suitability for Class I, Division 2.

For Zone 2 applications, install the Compact 

FieldPoint system in an enclosure rated to at least IP 54 
as defined by IEC 60529 and EN 60529.

This equipment has been evaluated as EEx nC IIC T4 equipment 
under DEMKO Certificate No. 03 ATEX 0251502X. Each module 
is marked 

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

locations.

For Zone 2 applications, connected signals must 

be within the following limits:

Capacitance .......................... 20 

µF max

Inductance ............................ 0.2 H max
