Approvals and Certifications
The IPS-4 Analyzer is certified with regard to electrical safety for Pollution Degree 2 (normally
nonconductive environmental pollution occurs with occasional condensation) and Installation
Category II (local level transients, less than those found at power distribution level). Mains sup-
ply voltage fluctuations are not to exceed 10 percent of the nominal supply voltage.
Approvals and certifications for the Zone1/Division1 Model include:
NEC/CEC: Class I Div 1 Groups A, B, C, D, Class II Div 1
Groups F & G, and Class III
Class I Zone 1 AEx d px IIC T3, Class I Zone 1
Ex d px IIC T3
ATEX: II 2 G ATEX Ex db pxb IIC T3 Gb IP65
NOTE - models with the 4660 sample system flowmeter installed are reduced to gas groups
BCD and IIB+H2.
