prolonged storage
Exceptionally if the device is
delivered separately from an
MCset FU and for prolonged
storage, the device must remain
in its original packing.
Following prolonged storage,
all insulating parts must be
thoroughly cleaned prior to use.
The enclosure will be dedusted
using a clean, dry cloth.
unpacking and handling
Exceptionally when the device
is delivered separately from
an MCset 1 FU.
H unpack the equipment
on the site of installation
H avoid impacts
Once you have unpacked the
device, handle it by lifting or
rolling.
preparation
handling by lifting
Sling up the device using the lifting
lugs and place it on the ground.
Unhook the slings and remove the
handling parts and their screws.
NB: the rings and screws must be
kept for future use.
handling by rolling
The device is handled using the
moving part extraction tool on a
smooth floor. It is handled by the
front face.
