Special conditions for safe use
It is required that:
● Electrical connections are in accordance with Elex V (VO in explosion hazardous areas) and EN60079-14 (Installing
Electrical Systems in Explosion Hazardous Areas).
● The protective cover over the power supply is properly installed. For intrinsically safe circuits the connection area can be
opened.
● Appropriate cable connectors are used for the output circuits: intrinsically safe: blue, non-intrinsically safe: black
● Sensor and transmitter are connected to the potential equalization. For intrinsically safe output circuits potential
equalization must be maintained along the entire connection path.
● Sensor insulation thickness is max. 100mm (only insulated sensors).
● EN50281-1-2 is considered for installation in areas with combustible dust.
● When protective earth (PE) is connected, no potential difference between the protective earth (PE) and the potential
equalization (PA) can exist, even during a fault condition.
WARNING
Laying of cables
Cable for use in zone 1 and 2 or 21 and 22 must satisfy the requirements for having a proof voltage 500 VAC applied
between the conductor/ground, conductor/shield and shield/ground.
Approved media
When using media, observe the following:
● Media (fluids) may only be used if, based on the state of the art or the operating experience of the user, it can be assured
that chemical and physical properties of the components coming into contact with the fluids will not be adversely affected
during the operating period.
● Specifically chloride media can cause non-visible corrosion damages to all media wetted components so that fluid can
lead. The suitability of these materials for each application by the operator to examine.
● Media (fluids) with unknown properties or abrasive media may only be used if the operator can perform regular and
suitable tests to ensure the safe condition of the meter.
● The information on the nameplate.
