PRIME 4 Installation and Operation Manual
Installation 4
• IEC 60079-1 7th Edition, EN 60079-1:2014
All cable entries, stopping boxes, or plugs should be certified according to the requirements in EN 60079-1
with 3/4-inch 14 NPT threaded entry. Wiring conductors and cable glands, if used, must have a tempera-
ture rating of at least 70 ºC.
For wiring systems using cable glands, the gland or thread adapter must be installed in accordance with
EN/IEC 60079-1 Section 13. The cable end must be securely installed and, depending on the cable type,
be properly protected from mechanical damage. Select wiring and cable glands suitable for 70 ºC ambient
operation.
For wiring systems using conduit, an Ex d certified sealing device must be used immediately at the
entrance of the J-Box enclosure. It is an end-user requirement to ensure that any unused entries must be
suitably blocked with an Ex d IIC IP with Ingress protection matching the name plate markings.
Equipotential bonding or earthing must be safeguarded by the way the sensor is connected with the
complete system.
Electrical Ratings: 28 VDC, 50 mA max.
2.4 UL Brazil-Approved Installations
Installed or connected components (e.g., terminal compartments, bushes, plugs, cable glands, connec-
tors) must have construction features that meet technical specifications for the CoC. They must be suitable
for the operating conditions and be separately certified. The special conditions specified for the compo-
nents must be met. This applies also to components shown and mentioned in the technical description.
The terminal compartment can be connected to suitable conduit systems that comply with the NBR IEC
60079-1 requirements and for which a separate certificate has been issued.
Openings in the enclosure that are not used must be closed/sealed in accordance with ABNT NBR IEC
60079-1 (for example, with the use of separately certified plugs).
Repairs to the sensor housing may only be made by the manufacturer or Ex d certified repair shops for
the 3/4-inch 14 NPT or 1/16-inch 27 NPT flame-proof joints.
Repairs on the basis of the values in Tables 2 and 3 of EN/IEC 60079-1 are not permitted.
