■ Operations
 Even if this product is deactivated by the occurrence of an event such as an
abnormality, when power is supplied to the inverter, do not bring any regions of your
body into contact with the inverter terminals. Contact during the power-on status of
Prohibited
the inverter can result in electric shock.
 Do not apply a dropping shock or other physical shocks.
Otherwise, damage or malfunction will result.
 Do not yank the interconnect cable.
Otherwise, damage or malfunction will result.
Prohibited

Do not disconnect the USB cable during communication with the inverter.
Otherwise, damage or malfunction will result.
■ Cautions in using the unit
Do not install the unit where it will be exposed to abrupt changes in temperature or
humidity.
Leave space between the interconnect cable (between the inverter and the USB
device) and the power cable from the inverter. Or the inverter could malfunction
because of noise.
Do not connect the conversion unit to more than one inverter. Connect the
conversion unit to either the "RS485 (2-wire type)" port or the "LOGIC" port on your
inverter, depending on the type of the inverter.
Avoid connecting the conversion unit to a USB hub or extended USB port (e.g.,
PCMCIA card). Or else the conversion unit may become unstable, depending on the
environment in which it is used.
■ Cautions in creating a software program
To allow an emergency stop by means of an external device, insert a magnetic
contact or similar device between the inverter and the power supply.
The communications software created based on the instruction manual for each
TOSVERT series communication function can be used as-is, if the COM port number
is changed properly. The conversion unit may, however, be detached from the
operating system as a result of a transmission error due to noise, and therefore the
occurrence of transmission timeout errors should be monitored using the software,
and if they occur in succession, open the port again.
