Introduction
Thank you for purchasing the “RS485 Converter Option Unit(RS4001Z)” for TOSVERT series
inverter. Read the safety precautions in the “Inverter Instruction Manual” before powering up your
inverter. Using this RS485 Option Unit, a communication between the inverter, which has the
common serial option (communication) connector, and a host computer is available.
Please read the entire manual carefully before attempting to control your inverter via RS485 serial
connection. Besides this instruction manual, the “Serial Communications Function Manual” is
needed to develop software which communicates with the inverter.
In addition, it has this manual kept to the operator using "RS485 Converter Unit", and please use it
for future maintenance and inspection.

About operation
Danger
Prohibited
▼
Do not wipe the body with a wet cloth.
It could lead to electric shocks.
▼ Do not pull on the cable
It could cause damage or error.
■
About disposal of the product
Cautions
Mandatory
▼
Dispose of the product as an industrial waste.
Unless it is disposed of as an industrial waste, it will become risks for human injury.
■
Cautions on use
Cautions
▼
Avoid installation locations that may be subjected to rapid changes in ambient temperature
or/and humidity.
▼
Route the transmission cable separate from the inverter input/output power wiring.
When disconnecting connection cable, make sure to hold its connector with care not to give
unreasonable stress to the cable and the unit.
▼
Since connectors of optional cables have locking
pawls for disconnection prevention at the inverter and the Option Unit, disconnect such a
connector while pressing the pawl by finger for unlocking.
▼
Mount the Option Unit securely on the panel, otherwise it could fall and cause malfunction or
breakdown.
▼
Connect an electromagnetic contactor or the like between the inverter and the power source to
secure external control of emergency stop of operation.
▼
Do not assign the same inverter number to more than one inverter in the same system.
▼
The inverter’s EEPROM has a life of 10,000 write cycles. Do not write to the same EEPROM
address more than 10,000 times.

4. Connection and start-up
■
Procedure
(1) Set the communication speed to SW on the RS-485 Option Unit.
(2) Connect terminating resistor in both ends of units. The RS-485 Option Unit has internal
terminating resistor. Set SW3 and SW4 to ON to connect these terminating resistors.
(Refer to a page 5)
(3) Install the RS-485 Option Unit on a metal panel.
(4) Connect the cable to the removable terminal block. If the stick-lugs are not used, strip the
insulation from the wire and insert the wire directly into the terminal. Be sure not to short any
wires. Wire the cable as shown in the figure. Use a common cable in the system.
(5) Connect the shield of the twisted pair cable to the SHIELD terminal on each RS-485 Option Unit,
and make the ground connection. Do not connect host computer ground to a power ground or
any other noise-producing ground connection.
(6) Insert the removable terminal block back into the RS-485 Option Unit.
(7) Connect the communication connectors (INVERTER1 and INVERTER2) of the RS-485 Option
Unit to the inverter’s common serial option (communication) connector of the with the optional
cable.
(8) Turn on the power of the inverter.
(9) Set the communication parameters of the inverter. (Refer to a page 9)
