Installation (continued)
Hazardous Class
Airbath/Airless Oven
Standard Configurations:
Certified by CSA C/US for use in Class I, Division 1, Groups A, B,C,D with
air or nitrogen purge
Certified by CSA C/US for use in Class I, Division 2, Groups A, B,C,D
Certified according to ATEX with air or nitrogen purge and purge control
for Zone 1 or Zone 2 (II 2 G c Ex py nA nC ib IIB+H2 T4 Gb)
Suitable for use in general purpose and non-hazardous areas.
Altitude Up to 2000m (6561 ft) for analyzers using 230 VAC Supply
Up to 3000m (9842 ft) for analyzers using 115 VAC Supply
Ambient Temperature and
Humidity (for Normal
Operation, Storage, and
Transport)
0 to 122 °F (-18 to 50°C) (application dependent**)
Minimums - 0°F (-18°C) and 0% humidity
Maximums -
Up to 104°F (40°C) at 50% relative humidity
Up to 86°F (30°C) at 80% relative humidity
Operational Maximums – The Maxum II may be operated at ambient
conditions of up to 122°F (50°C) (application dependent**) and 95%
relative humidity provided the electronic doors are not opened and the
electronics compartment is purged with clean, dry instrument air. The
instrument air must be dry enough to prevent humidity condensation inside
the electronics enclosure.
Note: If the Maxum II is exposed to high condensing humidity with the
electronics open or without dry purge air applied, then it must be allowed
to re-stabilize at the above stated conditions for at least 8 hours before
electrical power is applied.
** Depending on application characteristics such as number of detectors,
oven temperature, and electronic loading, the acceptable ambient
temperature range may be reduced. Consult factory for application-specific
detail.
AC Power Wiring should be rated for 80°C (176°F) or higher.
Mains buffering (maximum power interruption): >20 ms
