9.7.1 Power-up sequence
Best practice is to power up all instruments in a station simultaneously from a single power
supply. If this is not possible, first power up VOLT 100 seriess, then power up the GRANITE data
logger. This procedure will reduce the time required to syncronize the CPI bus.
See
(p. 39) for more information.
9.8 Earth ground connection
Earth grounding provides protection from static discharge, transients, and power surges. A
ground lug is provided on the VOLT 100 series for connection to earth ground, see
CPI ports view (left) and ground lug view (right)
(p. 11). Minimum 14 AWG ground wire is
recommended. The earth side of the connection should be to a grounding rod or other
grounded device.
9.9 Mounting in an enclosure
GRANITE data loggers and measurement module brackets have mounting holes through which
small screws are inserted into nylon anchors in an enclosure backplate.
