Hazardous Locations Approvals

Warning: Explosions could result in death or serious injury, besides financial damage.
Installation of this instrument in an explosive environment must be in accordance with the national
standards and according to the local environmental protection method. Before proceeding with the
installation check the certificate parameters according to the environmental classification.
Notes:
Ingress Protection (IP)
Ingress protection (IP W): Supplementary letter W meaning special condition defined as

default by Smar the following: Saline Environment approved - salt spray exposed for 200
hours at 35ºC.
(Ref: IEC60529)
Ingress protection (Type X): Supplementary letter X meaning special condition defined as

default by Smar the following: Saline Environment approved - salt spray exposed for 200
hours at 35ºC.
(Ref: NEMA 250)
Marking Label
Once a device labeled with multiple approval types is installed, do not reinstall it using any other
approval types. Scratch off or mark unused approval types on the approval label.
Maintenance and Repair
The instrument modification or replaced parts supplied by any other supplier than authorized
representative of Smar Equipamentos Industriais Ltda is prohibited and will void the Certification.
For Ex-d protection application
Only use Explosion Proof/Flameproof certified Plugs, Adapters and Cable glands.

As the instrument is non-ignition capable under normal conditions, the statement "Seal Not

Required" could be applied for Explosion Proof version regarding to conduits connection.
(CSA Approved)
In an Explosion-Proof/ Flame-Proof installation, do not remove the instrument housing covers

when powered on.

Electrical Connection
In Explosion-Proof installations the cable entries must be connected or closed using metal
cable gland and metal blanking plug, both with at least IP66 and Ex-d certification. The
unused cable entries should be plugged and sealed accordingly to avoid humidity entering,
which can cause the loss of the product's warranty. For water-proof applications all NPT
thread parts apply the proper water-proof sealant. (A non-hardening silicone group sealant is
recommended).
For Ex-i protection application
Connect the instrument to a proper intrinsically safe barrier.

Check the intrinsically safe parameters involving the barrier, equipment including the cable

and connections.
Associated apparatus ground bus shall be insulated from panels and mounting enclosures.

When using shielded cable, isolate the not grounded cable end.

Cable capacitance and inductance plus Ci and Li must be smaller than Co and Lo of the

Associated Apparatus.
