This chapter deals with service and maintenance procedures related to explosion protection only!
More detailled instructions about servicing and maintaining general purpose components of
X-STREAM gas analyzers are subject of the X-STREAM analyzer instruction manual.
POSSIBLE EXPLOSION HAZARD
Inspection, maintenance and service must be carried out considering all
related standards e.g. for „Inspection and maintenance of electrical
installations in hazardous areas“.
POSSIBLE EXPLOSION HAZARD
Service or replacement of safety related components or requiring to open
the instrument are permitted only if no hazardous atmosphere is present
and both the instrument and connected circuitry are de-energized!
Depending on the local regulation this may require a competent hot work
supervisor to issue a hot work permit.
POSSIBLE EXPLOSION HAZARD
After maintenance or replacement of parts concerning explosion protection
an authority on explosion protection has to verify that the analyzer still meets
the requirements for explosion protection before it is switched on again.
Parts essential for explosion protection must not be repaired, they must
be replaced if defective!
The authority has to issue a certi
fi
cate for this and/or attach a test label to
the equipment before startup after maintenance or replacement of parts.
