WARNING
Explosion
Failure to de-energize the analyzer may cause an explosion and severely injure personnel.
Before opening the analyzer, disconnect all electrical power and ensure that the area is
free of explosive gases.
Keep cover tight while circuits are live.
Use cables or wires suitable for the marked "T" ratings.
Cover joints must be cleaned before replacing the cover.
Conduit runs to the enclosure must have sealing fitting adjacent to enclosure.
