4.3.3. Umbilical
The umbilical is the backbone of the
NAVIC
system. It provides all power, network
distribution as well as encoder signal transmission. Circuitry is incorporated into
the umbilical to protect or isolate all signals. The umbilical provides separation
between the power controller and the crawler. Various umbilical lengths are
available from 5 m to 30 m
(16.4 ft to 98.4 ft)
long.
NOTE:
Before use, inspect the cable and connectors for damage. When any damage is
evident, the cable must
NOT
be used. Using a damaged cable may be a safety
hazard and could also put other system components at risk.

WARNING!
FALLING OBJECT HAZARD
.
Ensure the umbilical can freely uncoil during
operation and does not become snagged. If umbilical
becomes snagged, the crawler may fall and
SEVERE INJURY
or
DEATH
could result.
