1.2 Basic configuration
The following devices are required to operate the inverter. Proper peripheral
devices must be selected and correct connections made to ensure proper
operation. An incorrectly applied or installed inverter can result in system
malfunction or reduction in product life as well as component damage. You must
read and understand this manual thoroughly before proceeding.
AC Source
Supply
Use a power source with a voltage within
the permissible range of inverter input
power rating.
MCCB or Earth
leakage circuit
breaker (ELB) Select circuit breakers or fuses in
accordance with applicable national and
local codes.
Inline Magnetic
Contactor
Install if necessary. When installed, do not
use it for the purpose of starting or
stopping the drive. It can reduce the life of
inverter.
AC Reactor
An AC reactor can be used when the
harmonics are to be reduced and power
factor is to be improved. One must be
used when the inverter is installed on a
power source with greater than 10 times
the KVA rating of the drive.
AC Drive
(SV-iP5A)
Installation and
wiring
To reliably operate the drive, install the
inverter in the proper orientation and with
proper clearances. Please pay attention, if
the inverter is installed in the panel.
Incorrect terminal wiring could result in the
equipment damage. Control wire of control
circuit must be wired separately with main
ciruit wire to reduce the electric noise.
DC Reactor
A DC reactor may be used together with or
in place of an AC reactor if necessary to
reduce harmonics or improve power factor.
Motor
Do not connect power factor capacitors,
surge arrestors or radio noise filters to the
output side of the inverter.
