The electric signals on the remote sensor’s connection to equipment are of low intensity. Therefore,
when installing the cable inside the conduit (maximum limit 20 m eters length) keep it away from
possible sources of induction and/or magnetic interference. The cable supplied by Smar is shielded
for excellent protection against electromagnetic interference, but despite this protection avoid the
cable sharing the same conduit with other cables.
The connector for remote Hall sensor is easy handling and simple installation.
See the installation procedure:

Remote Hall Sensor

Positioner
Installation in Hazardous Areas
WARNING
Explosions could result in death or serious injury, besides financial damage. Installation of this
instrument in an explosive environment must be i n 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.
The instrument modification or replaced parts supplied by any other supplier than the authorized
representative of Smar Equipamentos Industriais Ltda is prohibited and will void the Certification.
The positioners are marked with options of the protection type. The certification is valid only when
the protection type is indicated by the user. Once a particular type of protection is selected, any
other type of protection can not be used.
The electronic housing installed in hazardous areas must have a m inimum of 6 f ully engaged
threads. Lock the housing using the locking screw (Figure 1.6).
Tighten the cover with at least 8 turns to avoid the penetration of humidity or corrosive gases.
Tighten the cover until it touches the housing. Then, tighten more 1/3 turn (120°) to guarantee the
sealing. Lock the covers using the locking screw (Figure 1.6).
Consult the Appendix A for further information about certification.
