2 Preparing for Installation

This chapter provides a site preparation checklist, safety information, unpacking instructions, and installation instructions.

Site Preparation Checklist

Before installing the 8620 DET, ensure the following items:

Adequate space for installation

The appropriate communication lines back to the FuelsManager Oil & Gas Terminal Automation system

Power (AC or DC)

Grounding

Enclosure protection, such as concrete barrier poles to prevent trucks from damaging the unit

General Safety Guidelines

The 8620 DET is certified to be used in Class I, Div 2, hazardous locations.

The user shall follow safety guidelines provided by the Occupational Safety and Health Administration (OSHA) for additional protection. Information may also be obtained from the following sources:

National Electrical Code (NEC)

National Fire Protection Association (NFPA)

Instrument Society of America (ISA)

FM Approvals (FM)

Underwriters’ Laboratories Incorporated (UL)

When in doubt about the safety of an area, check with the local safety authorities. Always observe equipment labels and warning signs posted in the area.

Installation Safety Guidelines

This equipment should be installed only by qualified personnel familiar with the installation of display and monitoring equipment.

Caution should be exercised when any area that is posted or otherwise assumed to contain hazardous gases. Always follow OSHA guidelines.

To prevent shock hazards, the housing of all units should be properly grounded in accordance with the National Electrical Code. A grounding conductor should be wired to the grounding terminal provided on the 8620 DET.

!Warning Before attempting installation of the 8620 DET, review the "General Safety Guidelines" above. Installation and maintenance personnel should become familiar with any hazards present as well as any agency requirements before working with any equipment.

Obtain a hot permit before opening the 8620 DET cover with power applied.
