CAIXS2-ab Intrinsically Safe Indicator
IS / I, II, III / 1 / ABCDEFG / T4 – Entity 66015-751-07
I / 1 / AEx ia IIC / T4 Entity 66015-751-07
a = U or V or blank
b = blank or up to three numbers (not relevant to safety)
Specific Conditions of Use
1.
The front panel of the intrinsically safe indicator type CAIXS2-…. is non-metallic
and shall not be used where UV light or radiation may impinge on the enclosure.
2.
The device shall be installed in such a way that it is protected against the entry of
solid foreign objects or water capable of impairing the safety of the apparatus. Reduce
the risk of mechanical damage to a minimum.
