Installing Your DeltaV System

This chapter provides detailed instructions and diagrams for system installation. It includes recommendations for planning the installation and provides a brief overview of the steps required for system installation.

This chapter describes installations that are mounted vertically on horizontal carriers.

For Class I Division 2 installations, refer to the document DeltaV Scalable Process System, Class I Division 2 Installation Instructions, (12P1293) on the DeltaV Documentation Library DVD.

For Zone 2 installations, refer to the document DeltaV Scalable Process System, Zone 2 Installation Instructions, (12P2046) 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 Stahl Series 8125/8126 enclosures are Emerson Alliance Program products.
• 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.
