Section 2—Installing the Scanner 2000
Overview
The Scanner 2000 microEFM is fully assembled at the time of shipment and ready for mounting. However,
Cameron recommends that operators configure the microEFM prior to mounting if the instrument is to be
installed in a hazardous area. The enclosure must be opened to configure the device, either via keypad controls
or via software, and once the instrument is mounted in a hazardous area, the cover should not be removed
unless the area is void of combustible gas and vapors.
Hazardous Area Installations
The Scanner 2000 is ATEX-certified (Zone 1) and CSA-certified (Div. 1 and Div. 2) for hazardous area
use. Installation requirements vary, depending on the certification required. Carefully review the following
hazardous area requirements before installing a Scanner 2000 in a hazardous area.
Zone 1 (ATEX) Installations
The ATEX-certified standard Scanner 2000 microEFM and the ATEX-certified Scanner 2000 microEFM with
expansion board are fully compliant with European ATEX Directive 94/9/EC, Annex II,1.0.6.
The following instructions apply to equipment covered by certificate number 07ATEX 1037X:

within Europe).
• Repair of this equipment shall be carried out by the manufacturer
or in accordance with the applicable code of practice (IEC 60079-

• If the instrument is likely to come into contact with aggressive
substances, the user is responsible for taking suitable precautions
to prevent it from being adversely affected, thus ensuring that the
