2.2 Standard connection

-Do not connect the power cables to any output terminal (U/T1, V/T2 or W/T3 on the
motor side), or the inverter could break down and cause a fire.
-Do not connect a resistor to any D.C. terminal (between PA and PC or PO and PC), or
Prohibited
the inverter could cause a fire.
To install external braking resistor, refer to 6.13.4.
-Connect grounding wires correctly and securely. Failure to do so could cause an
electric shock or a fire if current leakage occurs or the inverter breaks down.

* When using a separate power source
for the control circuit
For the 22kW and smaller models,
power is supplied to the control circuit
from the main circuit. An optional device
is required to
CN21
supply from
another source.
(though

are provided.)
*1: The control power supply terminals
RO and SO are optionally
available for the 22kW and
smaller models. Though terminals
RO and SO are fitted as
standard for the 22kW and
smaller models as well, they
are not connected internally.
*2: The inverter is shipped with
the terminals PO and PA
shorted with a bar. Remove
this shorting bar when installing
a DC reactor (DCL).
