Installation and Start-Up | 3-25
Always disconnect main AC power and/or external power sources
to the analyzer before opening any covers or doors on the analyzer to
check or perform maintenance on any components within the enclo-
sures.
If it is necessary to open the analyzer’s covers or doors while the
circuits are live, test the area for flammable gases (and proceed only
when the area is safe).
Purged Analyzer (Hazardous Location) Applications
To work on the analyzer with it powered up and its Electronics
Enclosure door open, the Purge Bypass Switch must be in the
“BYPASS” position.
When the Electronics Enclosure door is open, take appropriate precau-
tions to avoid electrical shock. Hazardous voltages are present inside.
Do not apply power to the analyzer if any of its flamepaths appear to
be scratched, dented, or worn. Applying power to an analyzer with a
damaged flamepath is dangerous and could result in serious injury or
death, and/or serious damage to equipment.
Replace parts immediately if damage or wear is apparent. Contact
AMETEK if there is any doubt about the integrity of any flamepath.
