1. Introduction

This manual should be read and understood in all its parts before proceeding
with installation of the sensor.
The Magnetic Sensors SMC-12 NO
in a potentially explosive atmospheres with presence of GAS and/or DUST.
They are designed and produced according to the requirements of the
following european standards:
* EN60079-0 - Explosive atmospheres - Part 0 : Equipment - General requi-
rements.
* EN60079-18 - Explosive atmospheres - Part 18 : Equipment protection by
encapsulation ''m''.

2. Installation and Startup

The sensor must be installed, connected and activated only by specialized
personnel. Personnel must be familiar with the types of protection
anti-ignition, the production rules and regulations in the potentially explosive
area. The user is solely responsible for the choice and the use of sensor
suitable to the final application. When installing the sensor observe the
following requirements:
Check whether the classification of the sensor is suitable for the application
(see''ATEX Marking'' to paragraph 5 and marking on the equipment).
Make sure that the connection cable of the sensor does not have the
endings too tight. Moreover it must not prevent the movement of people
and/or things.
Do not touch uninsulated parts of the connecting cable of the sensor before
having it disconnected from the supply voltage. Do not install the sensor
during a thunderstorm with lightning.
Make sure that the sensor housing is always ground wired.
If the cable is subject to movement, do not place the sheath with bending
radius too short; Pay attention to the mounting of the parties subject to
movement and to the fixed ones.
Separate the power cables from the connecting cable of the sensor.
Protect from the light the input zone of the cable into the housing .
