DANGER: As with all electrical devices, ensure proper grounding using
the ground lug of the device. Observe polarity (+/–) markings on the
charge connector, and do not apply voltages over 28 V.
•
Carefully install any solar panels, other power supply devices, antennae,
and cabling according to manufacturer recommendations. Use surge
suppression where possible. Consider the use of the Basic Grounding Kit
(pn 31163), the Bulkhead Surge Suppressor Kit (pn 31312), and Self-
Vulcanizing Shrink Tape (pn 21212). See this application note for more
information on using self-vulcanizing shrink tape:

•
WARNING: Close the lid of the enclosure and secure the latch when the
CRVW3 is deployed. This will help avoid unwanted entry of water, and
provide isolation from other environmental factors. IP66 protection is
available when using the four screws provided by the enclosure
manufacturer to seal the lid properly. Wipe off any water from the outside
of the enclosure before opening the enclosure lid.
When using multiple CRVW3 devices in an RF451 (or RF407)
radio network, it may be necessary to deploy an RF451 (or RF407)
device (in addition to those built-in to the CRVW3) to operate as
the
base radio station
in the network. Please consult with your
local Campbell Scientific support representative regarding the use
of radio options. Also refer to Section
(p. 51)
Complex (Large) Radio Networks
(p. 58)
, for more
information relating to the design and configuration of radio
networks.
