■Power supply switch(NFB) and earth leakage breaker
．
Choose the
p

l
y
switch
(
NFB
)
of
p
ro
p
er current
rating.
．
Do not use the
p
ower su
pp
l
y
switch
(
NFB
)
as the switch
that the inverter is used to control the runnin
g
or sto
p
o
f
motor.
．
When the earth leaka
g
e breaker installed to
p
rotect the
leaka
g
e current fault, be sure that the earth leaka
g
e breaker
has the sensitivit
y
am
p
era
g
e
≧
200mA
p
er inverter and
operation time ≧0.1 sec to avoid false-triggering.
■ Electromagnetic contactor
．
In normal o
p
eration,
y
ou don’t need an electroma
g
netic
contactor. However, you need to install an electro-
ma
g
netic contactor while in the case of se
q
uence control
throu
g
h the external device or automaticall
y
re-start after
power outage.
．
Do not use the electroma
g
netic contactor as the switch that
control the operation of running or stop.
■ AC reactor
．
The AC-side reactor on the in
p
ut AC side can im
p
rove the
power factor and suppress the surge current.
■ Input noise filter
．
7200MA will com
p
l
y
with the EN55011 class A re
g
ulation i
f
an input noise filter (specified by TECO) is used.

on page 24.
■ 7200MA inverter
．
In
p
ut
p
ower su
pp
l
y
can be connected to an
y
terminal
R/L1, S/L2, T/L3 on the terminal block. The
p
hase
se
q
uence of in
p
ut
p
ower su
pp
l
y
is irrelevant to
p
hase
sequence.
．
Please connect the
g
round terminal E to the site
g
round
securely.
■ Zero phase core
．
Install the zero
p
hase corer to eliminate noise transmitted
between the power line and the inverter.
．
Please refer to the selection
g
uide “1.9 Peri
p
heral device”
on page 25
.
■ Induction Motor
．
If one inverter is to drive more than one motors, the
inverter’s rated current should be much
g
reater than the
sum of total current of motors while in operation.
．
The inverter and the motor should connect to the
g
round
separately.
