GAA330-M EMISSION MONITORING SYSTEM
The device can be hazardous if the protective lead is interrupted inside or
outside the device or if the protective lead is disconnected.
Be sure the analyzer system voltage setting matches the line voltage before
connecting the power supply.
Current-bearing components can be exposed when the covers or parts are
removed, even if this can be done without tools. Current can be present at
some connection points.
All work on a device that is open and connected to power should only be
performed by trained personnel who are familiar with the risks involved.
The capacitors in the analyzer system can retain their charge even when it is
disconnected from all power sources.
Only fuses of the specified type and rated current should be used as re-
placements. Never use patched fuses. Do not short-circuit the fuse holder
contacts.
Do not open any gas paths in the analyzer system or in the integrated ana-
lyzers. Doing so will damage gas path seal integrity.
If system-internal gas paths are opened, a seal integrity check must be per-
formed with a leak detector (thermal conductivity) when the device is reas-
sembled.
If it is apparent that safe operation is no longer possible, the device should
be taken out of operation and secured against unauthorized use.
The possibility of safe operation is excluded:
If the device is visibly damaged,
•
If the device no longer operates,
•
After prolonged storage under adverse conditions,
•
After severe transport stresses.
