Cable test truck procedure
Preliminary instructions
With the cable test truck in service position and
the OneFit shutter open, the OneFit door interlock
is in locked position and prevents the door
removal.
Such condition intentionally prevents access to
live parts for safety.
It is mandatory to review the following procedure
and customize as needed to ensure no live parts
access will be possible without proper procedure
and tools to ensure personnel safety.
Such procedure shall be revised and approved
by the customer safety officer or person
responsible for the specific site equipment
operation to ensure it considers the available
tools and network configuration and provide
the safety conditions required.
Review the following procedure and customize
as needed to ensure no live part acces will be
possible without proper procedure and tools to
ensure personnel safety.
DANGER
DANGER
The operational need arises in case of cable
testing operation, as it is required to access the
terminals of the cable test truck to connect
testing equipment leads.
In the versions providing portable equipment for
earthing, the same equipment can be used to
provide safe earthing of a feeder cable side,
providing earth fault current capability up to
declared value. Rated values are available on
ratings label.
Upper or lower terminals are available depending
on original panel cable side.
WARNING
The earth fault capability needs to be
coordinated between the Cable test truck,
portable equipment for earthing, OneFit
earthing blade, earth connection to original
panel and earth conductors. Maximum earth
fault capability is limited by the component
with lowest capability in the above earthing
chain. Rated values of each component are
available on its ratings label.
