Approval information
Type 'n' certification
IEC 60079-0: 2011 Edition: 6.0
IEC 60079-11: 2011-06 Edition: 6.0
IEC 60079-15: 2010 Edition: 4
N7 Certification No. IECEx BAS 12.0054X
Ex nA ic IIC T5 Gc (-40 °C ≤ Ta ≤ +70 °C)
Maximum Working Voltage = 42Vdc
Special conditions for safe use (X)
1. When fitted with the 90V transient suppressors, the equipment is not capable of
passing the 500V insulation test. This must be taken into account upon installation.
2. 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.
