Installation and Configuration
5.5 About the connection
・Make sure that the communication line and the
power line are placed as far as possible from
each other. If the power line and the
communication line are placed close to each
other, the communication line will pick up noise
from the power line that can interfere with the
transmission.
・Make sure to set up the system, so that in an
event of a network failure, the inverter output
stops immediately.
(1)
In case the master detects an abnormality in
the connection, shut down the inverter
primary power supply.
(2)
Allocate function "like free run" or "reset" to
the inverter input terminals, accordingly,
when the master detects a connection
abnormality it turns on these terminals.
(3)
Configure the inverter so in case of a
connection abnormality, it stops, free run
stops or trip. (When the operation command
is received through Ethernet, the inverter
shipment settings are configured so that if
there is any abnormality in the connection the
inverter will immediately stop.)
For other information concerning the installation,
please refer to the inverter user's guide.
Connect the communication cable (Ethernet
cable), so it minimizes the tension and stress over
the connector. Furthermore, take the same
precautions when connecting the power cable (for
supplying the external power 24 VDC).
