WARNING
Hazard
from
unintended
switch
off
of
the
service
switch!
•
If
there
is
potentially
such
hazard,
the
service
switch
has
to
be
locked
in
position
“ON”
(drill
a
hole
into
handle
and
secure
it
with
a
padlock)
to
ensure
operation
in
case
of
fire.
Padlock
is
not
in
scope
of
de
‐
livery.

Operating
conditions
•
Do
not
operate
the
fan
in
an
explosion
‐
hazardous
atmosphere.
•
During
operation,
touching
the
impeller
must
not
be
possible.
•
Safety
components
must
not
be
bypassed
or
put
out
of
function.
•
The
fan
may
operate
inside
limits
declared
on
the
nameplate,
operation
over
50Hz
is
not
allowed.
•
Prevent
suction
of
foreign
particles,
this
can
destroy
the
fan.
•
Switching
frequency:
-
the
fan
is
intended
for
S1
continuous
duty!
-
the
controls
may
not
permit
any
extreme
switching
duties!
•
In
case
of
speed
control
via
frequency
inverter
(
min.
20
Hz
÷
max.
50
Hz!
),
make
sure
that
the
voltage
peaks
on
the
connection
terminals
of
the
fan
are
lower
than
1000
V
and
voltage
rise
velocity
is
lower
than
500
V/
μ
s
(IEC
34
‐
17).
ATTENTION
Hazard
with
risk
of
additional
costs
•
In
case
of
control
via
frequency
inverter
an
additional
EMC
shielding
could
be
needed
(not
serial).
•
For
speed
control
is
recommended
a
combination
of
frequency
inverter
and
appropriate
all
‐
pole
sinus
filter
(or
minimum
dU/dt
filter).
It
is
particularly
important,
if
the
supply
cable
is
long,
but
also
to
re
‐
duce
the
motor
noise.
It
may
only
be
abandoned,
if
proven,
that
the
voltage
peaks
on
the
connection
terminals
of
the
fan
are
lower
than
1000
V
and
the
voltage
rise
velocity
is
lower
than
500
V/
μ
s.
•
Subsequently
fitting
of
EMC
shielded
cable
from
motor
to
connection
box/service
switch
is
connected
with
disassembly
of
the
fan!
•
In
the
DVV
fans
there
are
not
any
two
speed
motors
in
Y230V/D400V
connection
built
‐
in;
two
speed
motors
are
only
in
Y400V/Y400V
or
Y400V/YY400V
connection.
•
Small
single
speed
motors
(Y400V)
are
in
motor
connection
box
connected
in
Y
;
it
is
impossible
to
change
the
connection
to
D230V
without
disassembly
of
the
fan
(for
eventual
3x230V
frequency
in
‐
verter).
NOTE
At
single
speed
motors
with
nominal
power
from
incl.
5,5
kW
(D400V)
we
recommend
“star
–
delta”
start
‐
ing.
For
this
purpose
all
7
wires
are
led
to
connection
box/service
switch.
