N7 IECEx Type n Approval
Certificate No.” IECExBAS09.0032X
Ex Na nL IIC T5 (T
amb
= – 40 to 65 °C)
NOTE:
N7 is valid with S001 and S002 Input Types
Special Conditions of Safe Use:
1. The component must be housed in a suitable component certified
enclosure that provides a degree of protection of at least IP54 and
meets the relevant material and environmental requirements of IEC
60079-0: 2004 & IEC 60079-15: 2005.
2. Provision must be made, external to the component, to ensure the
rated voltage of the component supply is not exceeded by transient
disturbances of more than 40%.
3. The electrical circuit is connected directly to earth; this must be taken
into account when installing the component.
