Section 3: Installation
The area in which the detector may be mounted must be in accordance with the certification of the
apparatus and in accordance with the standards of the appropriate authority in the country concerned.
Do not modify the enclosure or component parts as this will compromise the Hazardous Area
Certification.
Ensure all wiring and power supply to the detector is within specified operating parameters.
The GDU-Incus is a sealed unit with the exception of the terminal cover; the main enclosure is not to be
opened by anybody other than Emerson or Emerson authorized personnel. All warranties and
certification are nullified if these seals are broken or tampered with.
The GDU-Incus is supplied without cable glands. Ensure all cable entry threads are sealed with an
appropriate plug to eliminate water ingress and thread damage. At installation, all shipping cable entry
plugs are to be removed and replaced with suitably approved Ex d cable glands or blanking plugs to
meet hazardous locations requirements. If the GDU-Incus is to be installed in a ‘Zone 1’ Hazardous Area
an Exd barrier seal must be used.
Identification tags must be firmly secured to the GDU-Incus bracket in the position shown on
to prevent unwanted locally generated ultrasonic noise.
