Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90 V transient suppressor, it is incapable of
withstanding the 500 V isolation from earth test and this must be taken into account
during installation.
2. The enclosure may be made of aluminum alloy and given a protective polyurethane
paint finish; however care should be taken to protect it from impact and abrasion when
located in Zone 0.
N7 IECEx Type n
Certificate: IECExBAS08.0046X
Standards: IEC60079-0:2011, IEC60079-15:2010
Markings: Ex nA IIC T4 Gc (–40 °C ≤ T
Special Condition for Safe Use (X):
1. If fitted with a 90 V transient suppressor, the equipment is not capable of withstanding
the 500 V electrical strength test as defined in clause 6.5.1 of IEC60079-15:2010. This
must be taken into account during installation.
