■Power supply switch(NFB) and earth leakage breaker
．Choose the power supply switch(NFB) of proper current
rating.
．Do not use the power supply switch(NFB) as the switch
that the inverter is used to control the running or stop of
motor.
．When the earth leakage breaker installed to protect the
leakage current fault, be sure that the earth leakage breaker
has the sensitivity amperage≧200mA per inverter and
operation time ≧0.1 sec to avoid false-triggering.
■ Electromagnetic contactor
．In normal operation, you don't need an electromagnetic
contactor. However, you need to install an electro-
magnetic contactor while in the case of sequence control
through the external device or automatically re-start after
power outage.
．Do not use the electromagnetic contactor as the switch that
control the operation of running or stop.
■ AC reactor
．The AC-side reactor on the input AC side can improve the
power factor and suppress the surge current.
■ Input noise filter
．7200MA will comply with the EN55011 class A regulation if
an input noise filter (specified by TECO) is used.
．Please refer to the selection guide "1.9 Peripheral device"
on page 24.
■ 7200MA inverter
．Input power supply can be connected to any terminal
R/L1, S/L2, T/L3 on the terminal block. The phase
sequence of input power supply is irrelevant to phase
sequence.
．Please connect the ground terminal E to the site ground
securely.
■ Zero phase core
．Install the zero phase corer to eliminate noise transmitted
between the power line and the inverter.
．Please refer to the selection guide "1.9 Peripheral device"
on page 25
.
■ Induction Motor
．If one inverter is to drive more than one motors, the
inverter's rated current should be much greater than the
sum of total current of motors while in operation.
．The inverter and the motor should connect to the ground
separately.
