AC Source Supply
Use the power supply within the
permissible range of drive input power
rating (Refer to page 10).
MCCB or Earth
leakage circuit
breaker (ELB)
Select circuit breakers with care. A large
inrush current may flow in the drive at
power on.
Magnetic
Contactor
Install it if necessary. When installed, do
not use it for the purpose of starting or
stopping. Otherwise, it could lead to
reduction in product life.
Reactors
The reactors must be used when the power
factor is to be improved or the drive is
installed near a large power supply system
(1000kVA or more and wiring distance
within 10m).
Installation and
wiring
To operate the drive with high performance
for a long time, install the drive in a proper
place in the correct direction and with
proper clearances. Incorrect terminal wiring
could result in the equipment damage.
To motor
Do not connect a power factor capacitor,
surge suppressor or radio noise filter to the
output side of the drive.
