IB Certification Number: NCC 11.0699 X
Ex ia IIC T4 Ga (-60 °C ≤ Ta ≤ + 60 °C)
Special conditions for safe use (X):
1. When fitted with 90V transient suppressors, the
equipment is not capable of passing the 500V
insulation test. This must be taken into account upon
installation.
2. The enclosure may be made from aluminum alloy
with a protective polyurethane paint finish; however,
care should be taken to protect it from impact or
abrasion when located in Zone 0. The polyurethane
paint finish may constitute an electrostatic hazard and
must only be cleaned with a damp cloth.
3. When the equipment is installed, particular
precautions must be taken to ensure, taking into
account the effect of process fluid temperature, that
the ambient temperature of the electrical housing of
the equipment meets the marked protection type
temperature range.
