• The external control ground terminal is not isolated from the
Memory HiLogger’s chassis ground. Make certain that there will
be no potential difference between the external control ground
terminal and the ground of any connected device. Otherwise, the
Memory HiLogger or device could be damaged.
• To avoid electric shock, use the recommended wire type to con-
nect to the external control terminals, or otherwise ensure that
the wire used has adequate current-handling capacity and insu-
lation.
