Replacement
of
supply
module
You
can
switch
between
all
types
of
supply
modules
in
MULTICAL®
603.
For
example,
it
can
be
an
advantage,
for
a
period
of
time,
to
exchange
a
mains
‐
connected
supply
module
for
battery
in
a
building
which
has
varying
mains
supply
due
to
restoration
or
construction
work.
For
some
meter
configurations
battery
supply
is
not
a
practical
option,
e.g.
in
connection
with
frequent
data
communication.
However,
it
is
always
possible
to
switch
the
module
type
from
battery
supply
to
mains
supply
without
reconfiguring
the
meter.

Data
backup
in
case
of
interruption
of
supply
MULTICAL®
603
is
fitted
with
a
small
lithium
battery
(BR1632)
as
backup
for
the
meter’s
internal
clock
in
case
of
interruption
of
the
supply.
Independent
of
the
mounted
supply
module
the
meter
is
equipped
with
functionality
which
saves
all
current
register
counts
in
case
the
voltage
of
the
internal
3.6
VDC
supply
is
below
3.1
VDC.
When
the
supply
is
re
‐
established,
the
meter
continues
counting
from
the
value,
which
was
saved
when
the
supply
was
interrupted.

Danish
regulations
for
mains
connection

Installation

Electrical

27/09,
February
2009)
The
consumption
of
energy
and
resources
(electricity,
heat,
gas
and
water)
of
the
individual
consumer
is
to
an
increasing
extent
registered
by
electronic
meters,
and
often
equipment
for
remote
reading
and
remote
control
of
both
electronic
and
non
‐
electronic
meters
is
used.
General
regulations
for
carrying
out
installations
must
be
observed.
However,
the
following
modifications
are
permitted:
If
meter
or
equipment
for
remote
reading
or
remote
control
is
double
insulated,
it
is
not
necessary
to
extend
the
protective
conductor
to
the
connection
point.
This
also
applies
if
the
connection
point
is
a
plug
socket,
provided
that
it
is
placed
in
a
canning
which
is
sealable
or
can
be
opened
with
key
or
tool
only.
If
meter
or
equipment
used
for
remote
reading
and
remote
control
is
connected
to
a
safety
transformer
mounted
in
the
panel
and
direct
connected
to
the
branch
conductor,
no
on
‐
off
‐
switch
or
separate
overcurrent
protection
in
either
primary
or
secondary
circuit
is
required,
provided
that
the
following
conditions
are
fulfilled:
The
safety
transformer
must
either
be
inherently
short
‐
circuit
‐
proof
or
fail
‐
safe.
The
conductor
of
the
primary
circuit
must
either
be
short
‐
circuit
‐
protected
by
the
overcurrent
protection
of
the
branch
conductor
or
short
‐
circuit
safely
run.
The
conductor
of
the
secondary
circuit
must
have
a
cross
section
of
at
least
0.5
mm²
and
a
current
value
which
exceeds
the
absolute
maximum
current
deliverable
by
the
transformer.
It
must
be
possible
to
separate
the
secondary
circuit
by
separators,
or
it
must
appear
from
the
installation
instructions
that
the
secondary
circuit
can
be
disconnected
at
the
transformer’s
terminals.
General
information
Work
on
the
fixed
installation,
including
any
intervention
in
the
group
panel,
must
be
carried
out
by
an
authorized
electrician.
It
is
not
required
that
service
work
on
equipment
comprised
by
this
message
as
well
as
connection
and
disconnection
of
the
equipment
outside
the
panel
is
carried
out
by
an
authorized
electrician.
These
tasks
can
be
carried
out
by
persons
or
companies,
who
professionally
produce,
repair
or
maintain
equipment
if
only
the
person
carrying
out
the
work
has
the
necessary
expert
knowledge.
