CT specification.
NOTE: The units stored outside in
vertical position must be screwed on to

foreseen for a short period of time.
4. ASSEMBLY IN THE STRUCTURE
The transformer shall be set up in

It is very important that the surface on
which the CT will be set up is flat

5. CONTACT SURFACES PREPARATION
It is recommended to clean all aluminum
contact surfaces with sandpaper 150
grain in order to eliminate the oxidation
layer. Scrub the contact surfaces with a
metallic brush (diameter of the thread
0.3mm) and impregnate with grease of
the type "PENETROX" or equivalent. All
the surfaces must be completely
covered with grease.
For silver or tinned contacts, only clean
(do not use sandpaper) and polish the
side of the aluminum. Cleaning silver or
tinned surfaces with sandpaper could
cause damage to the protection layer.
