Installation
The
device
is
only
allowed
to
be
installed
and
operated
within
the
permissible
temperature
range.
Please
ensure
an
adequate
ventilation
and
avoid
all
direct
contact
between
the
device
and
hot
or
aggressive
gases
and
liquids.
Before
installation
or
maintenance,
the
unit
must
be
disconnected
from
all
voltage
‐
sources.
Further
it
must
be
ensured
that
no
danger
can
arise
by
touching
the
disconnected
voltage
‐
sources.
Devices
which
are
supplied
by
AC
‐
voltages
must
be
connected
exclusively
by
switches,
respectively
circuit
‐
breakers
with
the
low
voltage
network.
The
switch
or
circuit
‐
breaker
must
be
placed
as
near
as
possible
to
the
device
and
further
indicated
as
separator.
Incoming
as
well
as
outgoing
wires
and
wires
for
extra
low
voltages
(ELV)
must
be
separated
from
dangerous
electrical
cables
(SELV
circuits)
by
using
a
double
resp.
increased
isolation.
All
selected
wires
and
isolations
must
be
conform
to
the
provided
voltage
‐
and
temperature
‐
ranges.
Further
all
country
‐
and
application
‐
specific
standards,
which
are
relevant
for
structure,
form
and
quality
of
the
wires,
must
be
ensured.
Indications
about
the
permissible
wire
cross
‐
sections
for
wiring
are
described
in
the
Technical
Specifications.
Before
first
start
‐
up
it
must
be
ensured
that
all
connections
and
wires
are
firmly
seated
and
secured
in
the
screw
terminals.
All
(inclusively
unused)
terminals
must
be
fastened
by
turning
the
relevant
screws
clockwise
up
to
the
stop.
Overvoltages
at
the
connections
must
be
limited
to
values
in
accordance
to
the
overvoltage
category
II.
For
placement,
wiring,
environmental
conditions
as
well
as
shielding
and
earthing/grounding
of
the
supply
lines
the
general
standards
of
industrial
automation
industry
and
the
specific
shielding
instructions
of
the
manufacturer
are
valid.

Cleaning,
Maintenance
and
Service
Notes
