Preparation before wiring
:
Connect the protective ground wire (PE)
Connect
the
inverter
to
the
grounding
bar
through
the
protective
earth (PE)
to
achieve
grounding
protection.
Ø
Good
grounding
is
good
for
resisting
surge
voltage
impact
and
improving
EMI
performance
.
Therefore,you
need
to
ground
the
wire
before
connecting
the
AC,DC,and
communication
cables
.
Ø
For
a
single
-
machine
system,only
the
PE
cable
needs
to
be
grounded;For
a
multi
-
machine
system,the
PE
cables
of
all
inverters
need
to
be
connected
to
the
same
grounding
copper
bar
to
ensure
equipotential
connection
.
Ø
Disconnect
the
inverter
DC
switch,AC
side
circuit
breaker
or
switch
.
Ø
Measure the voltage and frequency of the public grid (voltage:AC 230V;
frequency:50Hz)
Ø
The
recommended
specifications
of
the
AC
output
switch
are

AC connection steps:
1.Pass the 5 wires (A,B,C,N and PE wires) through the AC shield,connect them to the
power grid,and then crimp the O/U terminal.
2. Lock the AC cable to the corresponding AC terminal.
3.Lock the protective cover on the inverter frame, and finally tighten the protective cover
hole.
