Before
doing
any
mechanical
or
electrical
work,
the
device
must
always
be
disconnected
from
the
power
supply.
Before
opening
the
device,
all
indicator
lamps
in
the
control
panel
must
be
off.
Even
after
disconnecting
the
power
supply,
the
intermediate
circuit
capacitor
is
still
at
a
dangerously
high
voltage.
Only
securely
wired
connections
are
permitted.
The
device
must
be
grounded
(IEC
536
Class
1,
NEC,
and
other
corresponding
standards).
It
must
be
ensured
that
the
voltage
and
frequency
indicated
on
the
type
label
of
the
CPH
2.0
pump
corresponds
to
the

We
recommend
installing
a
suitably
dimensioned
differential
circuit
breaker
for

Type:
Class
A
with
selectively
adjustable
leakage
current.
The
automatic
differential
circuit
breaker
must
be
marked
with
the
