Marine certified, Class 1 Div 2, Zone 2, and NAMUR installations

For Class I Division 2 installations, refer to the documents DeltaV™ Electronic Marshalling (Charm I/O Subsystem) Class 1 Division 2 Installation Instructions (part number 12P5401) and DeltaV™ S-series Digital Automation System Class 1 Division 2 Installation Instructions (part number 12P5402) on the DeltaV Documentation Library DVD.

For Zone 2 installations, refer to the documents DeltaV™ Electronic Marshalling (Charm I/O Subsystem) Zone 2 Installation Instructions (part number 12P5403) and DeltaV™ S-series Digital Automation System Zone 2 Installation Instructions (part number 12P5404) on the DeltaV Documentation Library DVD.

For NAMUR NE 21 installations, refer to the document DeltaV Digital Automation System Namur NE 21 Installation Instructions, (12P2822) on the DeltaV Documentation Library DVD.

For Marine Certified DeltaV installations, refer to the following installation requirements. These requirements allow the DeltaV system to support the reduced EMC interference requirements at the Marine Navigation Frequencies. Marine certification is approved for 24 V powered systems only. For additional requirements and for a list of the specific DeltaV equipment that is approved for marine installation, refer to the specific certifying agency.

For all exposed deck locations:

Install the DeltaV system in an IP66/NEMA 4 enclosure with EMC-reduction shielding (15 dB minimum) such as the Stahl Series 8125/8126 enclosures.
The door of the enclosure must remain closed during normal operation. Opening the door defeats EMC-reduction shielding and protection from electrostatic discharge. Open the door only for maintenance and repair performed by certified, trained personnel.
Include an EMC power line filter such as a Tyco S series or equivalent on all DC input leads at the DeltaV system's enclosure with the filter grounded at the enclosure.

For non-exposed deck locations:

Install the DeltaV system in an enclosure suitable for your environment with EMC-reduction shielding (15 dB minimum).
The door of the enclosure must remain closed during normal operation. Opening the door defeats EMC-reduction shielding and protection from electrostatic discharge. Open the door only for maintenance and repair performed by certified, trained personnel.
Include an EMC power line filter such as a Tyco S Series or equivalent on all DC input leads at the DeltaV system's enclosure with the filter grounded at the enclosure.

Note

All electrical installations must conform to applicable federal, state, and local codes and regulations. All installation and maintenance procedures described in this document must be performed by qualified personnel and all equipment must be used only for the purposes described.
