5-20 | IPS-4 Dual Bench (UV / IR) Analyzer
3. Power down the analyzer:
General Purpose (GP) applications:
Open the Electronics Enclosure door and disconnect AC power from
the analyzer and its temperature-control zone circuitry by opening the
Main AC Power, DC Power, Bench Heater, and Oven Heater (if used)
fuses. Refer to the Fuse Legend at the back of the Electronics Enclo-
sure for the locations of these fuses.
Purged Analyzers (Hazardous Locations):
Open the explosion-proof power-disconnect switch to disconnect
power from the analyzer and its temperature zone circuitry. If heated
Sample and Vent Lines are used, disconnect power to them. Open the
Electronics Enclosure.
Wait 5 minutes to allow the high-voltage capacitors in the source-
lamp power supply to discharge.
4.
GP Analyzers Only:
Turn off the Instrument Air supply to the analyzer and then close the
Aspirator Air valve.
Purged Analyzers:
The Instrument Air supply must always remain on for the Purge By-
pass Switch to operate properly.
