INFRA C22 Enclosure
The enclosure base is milled out of solid aluminum and includes:
•
A horizontal hole for wall-mounting (M6 or ¼” bolt).
•
A vertical hole for floor-mounting (M6 or ¼” bolt).
•
A front lid covering the two batteries.
•
A plug at the back of the enclosure covers a desiccant bag which
needs to be replaced at regular intervals (see chapter 9).
•
A plastic cap on the top covers the antennas. Removing this cap
gives access to the microSD memory card and SIM card but will
seldom need to be opened.
•
A separate hole at the lower left side of the unit may be used for
a wire to lock the unit to a fix and solid structure for theft
prevention.
•
Three mounting setoff screws, located on the back of the
instrument enable sufficient, secure and plumb contact between
instrument and uneven vertical (or near vertical) surfaces. These
screws are not used for mounting (attachment) but used to
ensure that the instrument is plumb in the vertical direction
when attached (mounted) to a vertical surface.
•
All lids, plugs and connectors are O-ring sealed.
Note! C22 instruments are not intended to be submerged in water.
