Before starting any work on the EL6010 gas analyzer, observe all explosion-
protection safety precautions.
While there is a risk of explosion, do not work on current-bearing components,
except intrinsically safe circuits, and do not work with equipment that poses an
ignition hazard.
The connection to the local potential compensation point must be made before all
other connections.
The EL6010 gas analyzer can be hazardous if potential compensation is inter-
rupted inside or outside the gas analyzer or if the potential compensation connec-
tion is interrupted.
Current-bearing components can be exposed when covers or parts are removed,
even if this can be done without tools. Current can be present at some connection
points.
The EL6010 gas analyzer must be disconnected from all power sources before
being opened for any work. All work on an gas analyzer that is open and con-
nected to power should only be performed by trained personnel who are familiar
with the risks involved.
While connected to power, the EL6010 gas analyzer housing should only be
opened when the surrounding environment does not pose an explosion threat.
The EL6010-... analyzer unit capacitors require 10 minutes to discharge after the
system is disconnected from all power sources. Observe the safety precautions
indicated on the housing.
In the capacitors of the EL6010-CU control unit dangerous energies can be stored
even after separation from the voltage source. The control unit housing must not
be opened if the surrounding atmosphere is an explosion risk. Observe the
warning advice on the housing cover on this subject.
When working with flammable and toxic sample gases, shut off the sample gas
supply and purge the sample gas path with nitrogen before opening the EL6010-...
analyzer unit housing.
If it can be assumed that safe operation is no longer possible, the EL6010 gas
analyzer should be taken out of service and protected against inadvertent use.
The possibility of safe operation is excluded:
• If the gas analyzer is visibly damaged
• If the gas analyzer no longer operates
• After prolonged storage under adverse conditions
• After severe transport stresses
