IMPORTANT
When used in hazardous locations, the computer supports peripheral cards rated
4 W maximum, and Class I, Division 2, Groups A, B, C, D, T4. For ATEX and IECEx
applications, operation in Group IIC Category 3 gas and dust environments is
supported.
At maximum computer temperature, consider the following:
• A PCI card that dissipates 4 W can experience a surrounding air
temperature up to 90 °C (194 °F
)
.
• A PCI card that dissipates 1 W can experience a surrounding air
temperature up to 85 °C (185 °F
)
.
ATTENTION: Do not discard the slot cover. If the add-in card is removed
in the future, the slot cover must be reinstalled to maintain agency
access requirements.
