Current transformers 10-13 (accessories)
The
connection
is
named
"CURRENT
SENSORS"
on
the
adhesive
sticker.
Current
transformers
are
not
included
as
standard.
The
job
of
the
current
transformers
is
to
continuously
measure
the
current
on
the
incoming
phases
in
the
house/system.
This
measuring
helps
the
program
ensure
that
the
power
never
exceeds
the
rating
for
the
main
fuse
by
releasing
any
power
‐
stage
in
the
electric
heater.
The
current
transformers
are
phase
selective,
i.e.
they
measure
each
phase
separately.
This
allows
the
system
to
decide
itself
which
phase
to
load.
This
also
ensures
that
the
3
phases
are
distributed
as
evenly
as
possible.
Installing
the
current
transformers
is
recommended
but
not
required.
It
is
possible
to
limit
the
maximum
electrical
power
for
the
electric
heater
in
the
display.
The
current
transformers
should
be
installed
on
the
incoming
feed
to
the
central
control
unit,
which
must
be
protected
against
overloads.
This
should
only
be
performed
by
an
authorised
electrician.
The
minimum
cable
area
for
the
connection
is
0.5
mm².
At
least
4
‐
lines
must
be
used.
Mount
the
transformers
by
threading
the
incoming
phases
through
the
transformer.
The
blue
cables
from
the
transformers
should
be
joined
together
and
connected
to
the
common
terminal
