industrial
installations
and
installations
powered
by
a
separate
230/24
V
safety
transformer,
for

mounted
in
a
control
panel.
The
module
includes
a
double
‐
chamber

10.6
Power
consumption
of
mains
connected
meter
The
gained
power
of
meters
connected
to
24
VAC
or
230
VAC
appears
from
the
marking
on
the
meter’s
front.
The
marking
states
an
average
maximum
value
for
the
meter’s
gained
power,
and
over
a
period
the
power
will
not
exceed
the
marking.
For
instance
short
periods
with
data
communication
require
a
short
‐
term
increase
of
the
energy
consumption,
whereas
longer
periods
without
data
communication
require
less
energy.
The
table
shows
examples
of
accumulated
yearly
consumption
for
MULTICAL®
403
with
various
supply
types.
For
battery
supplied
meters,
see
paragraph
10.4
concerning
battery
lifetimes.
