Dinel, s.r.o. CLM–36
Electrical connection can only be made when de-energized!
The source of the power voltage must comprise of a stabilised safe low power source with
galvanic separation. In the event that a switch-mode power supply is used, it is essential
that its construction effectively suppresses common mode interference on the secondary
side. In the event that the switch-mode power supply is equipped with a PE safety terminal, it
must be unconditionally grounded! Spark-safe devices type CLM–36Xi(XiT) must be powered
from a spark-safe power source meeting the above-mentioned requirements.
Due to the possible occurrence of an electrostatic charge on the non-conductive parts of
the sensor, it is necessary to ground all sensors intended for use in environments with an
explosion hazard type CLM–36Xi(XiT). This can be performed by grounding el. conductive
tanks or el. conductive tank lids, and in the case of el. non-conductive tanks using and
grounding an auxiliary plate electrode PDE-27.
In the event that sensor is installed in an outdoor environment at a distance greater than 20
m from the outdoor switchboard, or from an enclosed building, it is necessary to supplement
the electrical cable leading to sensor with suitable over voltage protection.
In the event of strong ambient electromagnetic interference, paralleling of conductors with
power distribution, or for distribution to distances over 30 m, we recommend using a shielded
cable and grounding the shielding on the side of the power source.
